We read every piece of feedback, and take your input very seriously. This functionality can be helpful, since it means we have to think carefully how an exclusion applies to each dependency. Lets review the classpath dependencies again. still both proposals will be better than lacking ability to configure this. Files are visited in depth-first prefix order, so that a directory is visited before its children. It seems like the Delete task should have some straightforward way to do this, similar to these: Thats cleaner syntax, but it still has the same behavior as my solution the directories are still left behind. But we still get this unfriendly warning on startup. 1 Answer Sorted by: 2 (Nearly) Everything can be found in Gradledocs A FileTree represents a hierarchy of files. This means one of those bindings needs to be removed from the classpath, which youll see shortly how to do using exclude rules. This also affects custom tasks with output annotations, for example: When the directory "node_modules" is cached it will be missing files, some of which are required for modules to behave correctly. Heres how to review all dependencies across all dependency configurations: Or to review the dependencies for a specific dependency configuration. You can vote up the ones you like or vote down the ones you don't like, and go to the original project Will just the increase in height of water column increase pressure or does mass play any role in it? Utils How does the theory of evolution make it less likely that the world is designed? In this article youll learn why youd want to exclude dependencies in the first place, as well as how to use each of Gradles exclude options.

Powered by Discourse, best viewed with JavaScript enabled. Types AntType class AntType Ant types which a FileCollection can be mapped to. Once again, within the closure we call the exclude method with a group and/or module. This has the advantage of being more explicit than an exclude rule, as it ties the dependency to be excluded and the replacement together in one place. about proposal described in this issue, I think that it is a breaking change when no exclude or include is defined, so that many Gradle users may observe regression in their builds. This can be used, for example, in an Ant element. By clicking Sign up for GitHub, you agree to our terms of service and Returns the content of this collection, asserting it contains exactly one file. could be seen by Copy task. Utils should look like this: To make Project accessible in buildSrc modify build.gradle by adding the following content: And - of course - because of the fact that groovy is a dynamic language chopBackgroundImage can be defined in the following way: Thanks for contributing an answer to Stack Overflow! Try out for yourself the SLF4J + Spring Boot example from this article in this GitHub repository. A dependency configuration is just a grouping of dependencies. Why add an increment/decrement operator when compound assignnments exist? You can obtain a FileTree The file/directory to be visited is passed to the given closure as a, Visits the files and directories in this file tree. Make default fileTree excludes behave less confusing, Document default exclusion pattern for ConfigurableFileTree, major bug: gradle 4.x.x does not compile classes in package structure containing directory named "cvs", Add an option to automatically exclude other project directories from target(), Allow configuring default excludes in a first class manner, Restore default excludes from the configuration cache, deprecate by warning the user whenever a default exclude matches something, telling them to exclude it themselves. Returns true if this element is a directory, or false if this element is a regular file. The given closure is used to configure the filter. How to format a JSON string as a table using jq? For the scenario where were confident that a transitive dependency should be excluded across all dependencies, Gradle offers exclusion rules against dependency configurations. Why do you need to delete a tree except for some files? Option 1) per-dependency exclude rules. Easily fixed by replacing name with module. WebLocale represents a language/country/variant combination. If youve come across a relevant scenario which hasnt been mentioned then please leave a comment below to start a discussion. File collections have some important attributes in Gradle. They can be: Lazy creation of a file collection is useful when you need to evaluate the files that make up a collection at the time a build runs. For example, a file tree might represent a directory tree or the contents of a ZIP file. It is represented by the FileTree interface. The FileTree interface extends FileCollection, so you can treat a file tree exactly the same way as you would a file collection. Several objects in Gradle implement the FileTree interface, such as source sets . Heres how the exclude syntax looks in the Groovy build.gradle. Actually disregard my work around for settings.gradle.kts it doesn't work consistently, perhaps the timing between when BuildSessionScopeServices.java is instantiated vs when settings.gradle.kts could explain the inconsistency. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Visits the files and directories in this file tree. Heres an example of an INVALID build script exclusion rule. All the following code samples are in Groovy, although each approach is also given in Kotlin where stated. for me, more easy to use and understand will be a flag useGlobalExclusions=false while creating FileTree. For reasons still unknown, when specifying an exclude in Gradle you pass a module key as opposed to a name key used when specifying a dependency. Making statements based on opinion; back them up with references or personal experience. In fact, this excludes the dependency from the compile, runtime, testCompile, and testRuntime classpaths! Any files which match the specified exclude patterns will be excluded from the filtered tree. Returns a FileCollection which contains the union of this collection and the given collection. @wolfs I just stumbled over this (node_modules caching use case) and updating the default excludes works, but doesn't change the cache key, so the old, broken output is still reused. You can check the dependencies in your own project using Gradles built-in dependencies task. Find centralized, trusted content and collaborate around the technologies you use most. WebThe following examples show how to use org.gradle.api.file.ConfigurableFileTree. So its findings bindings for both log4j and logback. Have a question about this project? Now I could write a script such that it specifically deletes a and d, but Id like to avoid having to modify the script if we happen to add an e directory. WebThe default behavior of Gradlecopy task is copy the file and keep their directory structure. Youll see later how to generate such a dependency graph yourself. Only files which match the specified include patterns will be included in the filtered tree. If user specifies some include which contains files excluded by default exclusion, these files should be "liberated", e.g. Information about a file in a directory/file tree. Files are visited in depth-first prefix order, so that a directory is visited before its children. Can I contact the editor with relevant personal information in hope to speed-up the review process? WebBest Java code snippets using org.gradle.api.file. If magic is programming, then what is mana supposed to be? Since some of them have the same name, we will need to rename them while copying to avoid file name conflict. For example, if you included both the Logback and Log4J bindings youd get this error. Generally, this method is more efficient than calling getFiles().contains(file). Can we end this game of whack-a-mole permanently? Reasons to exclude dependencies. FYI, Im mimicking an existing (brittle) Ant build, and am constrained by how much logic I can change w/o introducing risk.

Connect and share knowledge within a single location that is structured and easy to search. No warnings on startup now. calling. For example, Googles popular Guava utility library pulls in several transitive dependencies, such as com.google.code.findbugs:jsr305. What does that mean? The file/directory to be visited is passed to the given action as a. Any files which match the specified exclude patterns will be excluded from the filtered tree. Ant supports this like so: So ultimately I could just use AntBuilder under the hood. The contents of the file tree represent the source files of this set, arranged in a hierarchy. SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory], 'org.springframework.boot:spring-boot-starter-logging', 'org.springframework.boot:spring-boot-starter-log4j2', "org.springframework.boot:spring-boot-starter-web:2.5.3", "org.springframework.boot:spring-boot-starter-log4j2:2.5.3", "org.springframework.boot:spring-boot-starter-logging", "org.springframework.boot:spring-boot-starter-log4j2", ./gradlew dependencies --configuration . The returned tree is live, so that changes to either this tree or the other source tree are reflected in the returned tree. 1 Answer Sorted by: 3 fileTree is a method defined on Project interface so there's a need to pass project instance to method and import Project class in Utils. I was thinking that not is here " the default exclusion should be applied" :). rev2023.7.7.43526. Generally, calling this method is more efficient than calling getFiles().isEmpty(). Ryan_Nelson (Ryan Nelson) July 1, 2013, 8:20pm #1 The semantics around deletion are very confusing to me. The filtered collection is live, so that it reflects any changes to this collection. Some variations include: This is probably too late for 5.0, but I wonder if we should consider deprecating this in 5.1 @oehme? When you declare a dependency in your build script, Gradle automatically pulls any transitive dependencies (dependencies of that dependency) into your project. The returned collection is live, and tracks changes to both source collections. A org.gradle.api.tasks.util.PatternFilterable is passed to the closure as its delegate. FileTree.matching (Showing top 20 results out of 315) org.gradle.api.file FileTree matching. Returns the path of this file, relative to the root of the containing file tree. When using the SLF4J logging framework, we should only have one binding to a logging implementation on the runtime classpath. @pun-ky Why do you think it is a breaking change?

What if we have a dependency that were absolutely sure should never be included though? to sum up, I am convinced that Gradle API need to be changed / have an option to control that default global exclusions working correctly in case of existing builds and new plugins that will want to use that control ability. The per-configuration exclude rule for this in the Groovy build.gradle looks like this. Returns the contents of this collection as a platform-specific path. Why was the tile on the end of a shower wall jogged over partway up? FileTree.visit (Showing top 20 results out of 315) org.gradle.api.file FileTree visit. Guavas pulling in a lot of extra stuff! It extends FileCollection to add hierarchy query and In the above example though, all combinations would result in the following updated transitive dependencies appearing on the classpaths. The file tree is live and reflects changes to the source directories and their contents. Another difference between using the exclude method and declaring dependencies is that you cant pass a string instead of a map. If we wanted to we could exclude, for example, the findbugs dependency. And heres how that looks in the Kotlin build.gradle.kts. On the surface this seems like an innocent change, but how do the classpaths look now? For a full understanding of using the dependencies task, as well as other troubleshooting options available in Gradle, I highly recommend signing up to the Gradle Hero course. We and our partners use cookies to Store and/or access information on a device. Copies this file to the given target file. The default behavior of Gradle copy task is copy the file and keep their directory structure. Youll have to use the Ant functionality in the meantime Im afraid. Here are the dependencies on the runtime classpath ( indicates entries left out for clarity). For 6.7, there is now a little bit of improvement regarding default excludes: Default excludes can be changed in settings.gradle and they will take effect immediately and consistently during a build: #13694. Archives are essentially self-contained file systems and Gradle treats them as such. This is why working with archives is very similar to working with files and directories, including such things as file permissions. The directory in question contains a mix of both source and content. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. Thats because jackson-datatype-guava depends on guava, meaning all of guavas transitive dependencies get pulled in again by Gradle.

But, Gradle offers a way to exclude dependencies from all dependency configurations. At this point rather than excluding logback-classic, we can actually exclude the whole spring-boot-starter-logging dependency in favour of spring-boot-starter-log4j2, so our exclude rule looks like this. This shows that we have one less dependency now. separator, regardless of platform file separator. You typically use a FileTree to represent files to copy or the contents of an archive. When you specify a dependency in your build script, you can provide an exclude rule at the same time telling Gradle not to pull in the specified transitive dependency. Allow Necessary Cookies & Continue We can safely exclude it as we wont be calling the Log4j 2 APIs within our application, only the SLF4J APIs.

You signed in with another tab or window. The Delete task doesnt appear to support any include or exclude, so I tried this: FileTree tree = fileTree (dir: tempDir); Unforunately, probably due to the problem described by Peter on SO here, this deletes the files during configuration phase, rather than execution phase. The given pattern set is used to configure the filter. blindpirate mentioned this issue on Sep 21, 2017. In Java projects these dependencies make their way onto the compile or runtime classpaths. Unfortunately in this case the DirectoryScanner workaround does not appear to work. Suppose, you have multiple project directories, each of them contains one or more markdown files, these files may nested deep in the directory structure. Adds another collection to this collection. We can achieve this with the following entry in our Groovy build.gradle. Already on GitHub? Now you want to collect them and copy them into one place, that means all the md files will be copied to one location. Files are visited in depth-first prefix order, so that a directory is visited before its children. Its also entirely valid to pass only group or only module to match more generically. Returns true if this collection is empty. You can call this method in your build script using the - operator. How do I get Gradle to do what I want? To be clear, this is in build.gradle: and in Utils.groovy (which is in buildSrc/src/main/groovy): fileTree is a method defined on Project interface so there's a need to pass project instance to method and import Project class in Utils. Some combinations of transitive dependencies in a project can cause issues, but fortunately Gradle has several ways to exclude those unwanted dependencies. This time we pass a closure to the dependency configuration. Thanks, it works fine. almost, lowercase "S" :). Copies the content of this file to an output stream. See Java and Groovy can not pass parameter by reference about why the listFilesRecursive is implemented like this. Always uses '/' as the hierarchy To see all available qualifiers, see our documentation. edited. You can obtain a ConfigurableFileTree instance by calling org.gradle.api.Project#fileTree(java.util.Map). Findbugs has sneaked its way back in again! The Delete task doesnt appear to support any include or exclude, so I tried this: task cleanTempDir (type: Delete) { FileTree tree = fileTree (dir: tempDir); This is equivalent to the name used to declare a dependency in Gradle. Findbugs successfully squished again! You switched accounts on another tab or window. We will append a number to the end of file name and increase the number for each copying. Returns the path of this file, relative to the root of the containing file tree. WebThe default behavior of Gradle copy task is copy the file and keep their directory structure. A FileTree represents a hierarchy of files. Heres how the dependencies look in the build script. With only the per-configuration exclude rule applied, the compile and runtime classpath dependencies look like this. Generally, calling this method is more performant than calling, Copies the content of this file to an output stream. The text was updated successfully, but these errors were encountered: in my opinion there should be at least a flag in project.fileTree(baseDir, globalExcludes=true) to remain existing behavior and be able to control that functionality. org.gradle.api.Project#fileTree(java.util.Map). There doesn't seem to be a way in which we can override this: gradle/subprojects/core/src/main/java/org/gradle/internal/service/scopes/BuildSessionScopeServices.java, Actually there is a work around but it's global the changes to DirectoryScanner must be done in settings.gradle.kts. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page..

Sometimes we only need to use a very small part of a dependency artifact. This could be helpful, for example, if you had the same dependency on the annotationProcessor path and wanted to exclude it. . in other words, you'd like to be able to whitelist explicitly global exclusions (make them noneffective). One such dependency configuration is implementation, which is a group of dependencies that appear on the runtime and compile classpaths. WebReturns the path of this file, relative to the root of the containing file tree.

For example, say we have a Gradle project that depends on Googles Guava library, or more specifically com.google.guava:guava:30.1.1-jre. The neuroscientist says "Baby approved!" Now you know what problems you might see with transitive dependencies, lets explore how Gradle solves them. Even if we add more dependencies which transitively depend on findbugs, it wont appear on our classpaths. WebFileTree (Gradle API 8.2) Interface FileTree All Superinterfaces: AntBuilderAware, Buildable, FileCollection, java.lang.Iterable All Known Subinterfaces: You can call this method in your build script using the + operator. Equivalent to calling addToAntBuilder(builder, nodeName,AntType.ResourceCollection). The SLF4J logging library requires that only one binding appears on the classpath, otherwise it doesnt know which implementation to use for logging. The source directories need to be deleted and redeployed to, whereas the content directories are quite large and need to be left alone. This is also the same approach suggested by the Spring Boot Logging docs. I dont understand why, since it seems to me the call to delete should be on the Delete task. One alternative suggested in the Spring Boot documentation is to replace a dependency rather than exclude it. You can probably guess which classpaths they end up on. Locating files build.gradle // Using a relative path File configFile = file ( 'src/config.xml' ) // Using an absolute path configFile = file (configFile.absolutePath) // Other dependency configurations in Java projects include runtimeOnly and compileOnly. Lets use example from earlier, where we declared an implementation dependency on guava, which transitively depended on findbugs. Ive raised GRADLE-2822 for this. This is fixed by replacing the string with a map. How to import files while loading a groovy class? Say we just wanted to use a tiny subset of Guava, like the endlessly helpful ImmutableMap.of(K k1, V v1) method. The given type determines how this collection is added: Adds this collection to an Ant task as a nested node. We can also pass a reason for the replacement to help with issue diagnosis. Same as calling. isDirectory () Returns true if long. This fixes the exception and now the logging framework can actually be used. Of course if were taking such an approach we need to be confident that the excluded library wont be required now or at any time in the future. Since there's no way to disable default exclusion explicitly, I propose some change in inclusion and exclusion mechanism: No way to disable default exclusion inherited from Ant. If youre having problems check out these common errors from my own experience and those of others online. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.

As a Gradle plugin developer now I am forced to have in my task such workaround: and I am afraid that could introduce an impact in case of task concurrency, because of such static variable inside directory scanner implementation. The returned collection is live, and tracks changes to both source collections. Currently the default excludes are always in-place, so the behavior wouldn't change in case neither include nor exclude is specified. Within the closure we call exclude, passing: group the group of the artifact we want to exclude. SourceDirectorySet extends FileTree. You can obtain a FileTree instance using org.gradle.api.Project#fileTree(java.util.Map), org.gradle.api.Project#zipTree(Object) or org.gradle.api.Project#tarTree(Object). I want to delete a subset of files in a directory during task execution. But we can write a helper function which will list the files and filter out files ends with md extension and pass them to from, so the from accept file list, not just a directory.
