John S Asks: Change working directory for gradle multi-module project I'm a new Gradle user coming from Maven and I've hit a bit of a roadblock in our CI builds due to the issue with the working directory in a multi-module build. Step 1 Verify JAVA Installation First of all, you need to have Java Software Development Kit (SDK) installed on your system. Consider the following example that copies files into a directory structure that can be used by a Java Servlet container to deliver a website: This is not a straightforward copy as the WEB-INF directory and its subdirectories dont exist within the project, so they must be created during the copy. Declaring Dependencies between Subprojects, Understanding Configuration and Execution, Writing Custom Gradle Types and Service Injection, Understanding Library and Application Differences, Producing and Consuming Variants of Libraries, Modeling Feature Variants and Optional Dependencies, Global cache directory (for everything thats not project-specific), Version-specific caches (e.g. For the complete default exclude list, see the Ant manual. The result is a collection of ZIP file trees, the contents of which are copied into the uber JAR alongside the application classes. You will also find that many parts of the Gradle API use FileCollection, such as the copying API discussed later in this chapter and dependency configurations. Something else to consider is what type of thing a file path refers to: A directory this is effectively treated as a file tree: everything in it, including subdirectories, is copied. If you want to change the name and location of a generated archive file, you can provide values for the archiveFileName and destinationDirectory properties of the corresponding task. The file() method can be used to configure any task that has a property of type File. Here is an example which maintains a copy of the projects runtime dependencies in the build/libs directory. Making statements based on opinion; back them up with references or personal experience. The jdkHome compiler option is deprecated . Creating a Java uber or fat JAR, Example 14. Build directory is a project property. toArchive/reports. The proposed directory structure might look like this: Figure 6.2. Getting Started. One final thing to be aware of is that a child copy spec inherits its destination path, include patterns, exclude patterns, copy actions, name mappings and filters from its parent. More advanced processing can be handled by the eachFile() method. How to create a release signed apk file using Gradle? You can locate a file relative to the project directory using the Project.file () method. an absolute path? Archives are effectively self-contained file systems, so unpacking them is a case of copying the files from that file system onto the local file system or even into another archive. We might also be interested in creating a war file with a custom name and version. if the gradle file is in /usr/ci/build.gradle, and one want to build source code in /usr/tmp/workspace/myproject and one uses file(foo.txt) it tries to open it in /usr/ci ? a WAR file). 2. The file() method (and friends) always resolve files relative to the project directory, not the JVM working directory. Using Copy to install an executable, Example 45. Using multiple arguments with from(), Figure 1. Copying files using the copy() method without up-to-date check, Example 41. It provides some conventional values for those properties. Creating an exploded WAR for a Servlet container, Example 40. If you want to use a path thats relative to the root project directory, then you need to use the special Project.getRootDir() property to construct an absolute path, like so: Lets say youre working on a multi-project build in a dev/projects/AcmeHealth directory. You can set each of these properties on the task separately if you wish. The answer is to add it as an include pattern: Youll get the same behavior as before except with one extra level of directory in the destination, i.e. And then we need to build our applications to download all their dependencies, otherwise, we will fail when we try using the offline mode. Android | build.gradle. You can use a Copy task to install the executable into shared directories like /usr/local/bin. 5. 2 comments Closed . You configure the character set with the. whether theres a corresponding version-specific cache directory.Unused distributions are deleted. Then select tab Gradle. Define one or many initialization scripts with the desired logic. You still want to take advantage of Gradles copy API, but without introducing an extra Copy task. With Gradle, all the previous steps can be automated in just a couple of easy steps. This example from the same project as the one above configures just the archiveBaseName property, overriding the default value of the project name: You can also override the default archiveBaseName value for all the archive tasks in your build by using the project property archivesBaseName, as demonstrated by the following example: You can find all the possible archive task properties in the API documentation for AbstractArchiveTask, but we have also summarized the main ones here: The complete file name of the generated archive. The base name portion of the archive file name, typically a project name or some other descriptive name for what it contains. You can learn more in this issue. The solution is to use the Project.copy(org.gradle.api.Action) method. The project root directory contains all source files that are part of your project. One task might copy the resources to a folder for a local HTTP server and another might package them into a distribution. The cleanup runs in the background when the Gradle daemon is stopped or shuts down. How to run Gradle test when all tests are UP-TO-DATE? Almost every Gradle build interacts with files in some way: think source files, file dependencies, reports and so on. For example, to make a Zip task reproducible you need to set Zip.isReproducibleFileOrder() to true and Zip.isPreserveFileTimestamps() to false. Create the build.gradle file to the root directory of the core project. Bear these rules in mind when creating combined inclusion and exclusion specifications so that you end up with the exact behavior you want. It is roughly structured as follows: From version 4.10 onwards, Gradle automatically cleans its user home directory. Why are only 2 out of the 3 boosters on Falcon Heavy reused? Live collections are also important when it comes to filtering. The Sync task, which extends the Copy task, copies the source files into the destination directory and then removes any files from the destination directory which it did not copy. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Gradle makes this approach easy to accomplish. Double-click the ZIP archive to expose the content. The directory. The following task definition does the necessary work: Notice how the src/dist configuration has a nested inclusion specification: thats the child copy spec. The target directory in which to put the generated archive. In other words, it synchronizes the contents of a directory with its source. The full power of copy specifications are available to you when creating archives, which means you can do content filtering, file renaming or anything else that is covered in the previous section. Sorted by: 36. You can put the following line in your build script: buildDir = 'your_directory'. Changing default excludes in the settings script, Example 30. When you are building a standalone executable, you may want to install this file on your system, so it ends up in your path. Normally, we strongly recommend that your build.gradle should not depend on the working dir. Many tasks, though, work on multiple files, so we look at how to specify sets of files next. You could manually specify the file locations and appropriate inclusions each time they are needed, but human error is more likely to creep in, resulting in inconsistencies between tasks. Project root directory Gradle uses two main directories to perform and manage its work: the Gradle user home directory and the Project root directory . You will probably also notice that into() is configured lazily using a closure (in Groovy) or a Provider (in Kotlin) a technique that also works with from(): Note that the lazy configuration of into() is different from a child specification, even though the syntax is similar. test { useTestNG() systemProperties = System.properties println "WD for tests of subproject " + project + " is " + workingDir } But in my test code the Java working directory . Declare the JUnit dependency (version 4.11) and use the testCompile configuration. Instead of using the fileTree() method, which only works on normal file systems, you use the Project.zipTree(java.lang.Object) and Project.tarTree(java.lang.Object) methods to wrap archive files of the corresponding type (note that JAR, WAR and EAR files are ZIPs). Connect and share knowledge within a single location that is structured and easy to search. Each type of archive has its own task type, the most common ones being Zip, Tar and Jar. When you run the program, the output will be: Working Directory = C:\Users\Admin\Desktop\currDir. the archive file itself. To learn more, see our tips on writing great answers. All core Gradle tasks ensure that any output directories they need are created if necessary using this mechanism. Alternatively, you can remove all doubt by explicitly using ProjectLayout.files(java.lang.Object) in your build. 0 JetForcer You can also perform more complex logic by using a closure that takes a FileTreeElement and returns true if the file should be included or false otherwise. Is there a way to configure this to e.g. 2. If you encounter a scenario in which you want to apply the same copy configuration to different sets of files, then you can share the configuration block directly without using copySpec(). The following cleanup strategies are applied periodically (at most every 24 hours): Version-specific caches in caches// are checked for whether they are still in use.If not, directories for release versions are deleted after 30 days of inactivity, snapshot versions after 7 days of inactivity. Various people have written (and published) scripts to execute gradlew from any subproject directory (in a multi-project build). There is no way at the moment to force the working dir of gradle process. The following example comes from a project named archive-naming, hence the myZip task creates an archive named archive-naming-1.0.zip: Note that the name of the archive does not derive from the name of the task that creates it. If youre a Java developer and are wondering why there is no jarTree() method, thats because zipTree() works perfectly well for JARs, WARs and EARs. 1 You need to add the following to your build.gradle file to modify the working directory of a gradle task. Exec task declares output and inputs. In addition, we only want HTML and image files going directly into the root folder build/explodedWar and only JavaScript files going into the js directory. Configuration of archive task - appendix & classifier, Example 49. In this tutorial, we'll learn about Gradle Wrapper, an accompanying utility that makes it easier to distribute projects. The filename extension for the archive. The following example shows how you can remove the string "-staging-" from any filename that contains it using a simple regular expression: You can use any regular expression supported by the Java Pattern class and the substitution string (the second argument of rename() works on the same principles as the Matcher.appendReplacement() method. We talk more about the difference between file trees and file collections in the File trees section. The appendix portion of the archive file name that comes immediately after the base name. Moreover, with Gradle, it becomes also feasible to handle . By entering your email, you agree to our Terms and Privacy Policy, including receipt of emails. So be careful where you place your configuration. Manually creating a directory, Example 15. You copy a file by creating an instance of Gradles builtin Copy task and configuring it with the location of the file and where you want to put it. Go to File -> Settings. Renaming files as they are copied, Example 17. Hence it doesnt make sense to define a standalone copy spec without at least one from() defined. Both of these methods are normally used with Ant-style include or exclude patterns, as described in PatternFilterable. ), CopySpec.with(org.gradle.api.file.CopySpec), Mirroring directories and file collections with the, Deploying single files into application servers, Sharing content between multiple archives, Extracts only the subset of files that reside in the, Remaps the path of the extracting files into the destination directory by dropping the, Ignores the empty directories resulting from the remapping, see Caution note below, Its good practice to specify the character set when reading and writing the file, otherwise the transformations wont work properly for non-ASCII text. It is typically used to distinguish between different forms of content, such as code and docs, or a minimal distribution versus a full or complete one. You can do many of the same things with file trees that you can with file collections: filter them (using FileTree.matching(org.gradle.api.Action) and Ant-style patterns). All AbstractArchiveTask (e.g. How can I force gradle to redownload dependencies? https://docs.gradle.org/current/userguide/writing_build_scripts.html, (Current version of gradle when writing this: 4.5), You can add project.buildDir = 'your/directory' to the file build.gradle rev2022.11.3.43005. In the following example, we query the file system to find out what files exist in a particular directory and then make those into a file collection: The key to lazy creation is passing a closure (in Groovy) or a Provider (in Kotlin) to the files() method. du shows that the directory doesn't exist.. Expected behavior Downloaded dependencies should be cached. Specifically, if you plan to add a method to configure a collection-based property, make sure the method appends rather than replaces values. The expand() method treats the source files as Groovy templates, which evaluate and expand expressions of the form ${expression}. Gradle adds some concepts and APIs to help you achieve this. 2022 Moderator Election Q&A Question Collection. Gradle provides the Project.file(java.lang.Object) method for specifying the location of a single file or directory. From Need a simple way to set working directory for Run and Debug: It is technically possible to do this by creating a custom run task like this: In this case you can specify a -PrunWorkingDir=. Build is executed. Gradle distributions in wrapper/dists/ are checked for whether they are still in use, i.e. Error compiling a Groovy project using @Grab annotation. For example, the simple task to copy some files from one directory to another can be performed by the Gradle build script before the actual build process . A particularly common requirement is copying files into subdirectories of the archive that dont exist in the source folders, something that can be achieved with into() child specifications. However, if our installed version doesn't match with the project's version, we'll probably face many incompatibility problems. Instead of new File (projectDir, "foo.txt"), just use file ("foo.txt"). The return value is live and the provided path is queried each time the return value is queried. You can even pass in tasks as arguments if they have defined outputs. LO Writer: Easiest way to put line of words into table as rows (list). Chapter 16. In the following example, we create a new collection that consists of only the files that end with .txt in the source collection: If collection changes at any time, either by adding or removing files from itself, then textFiles will immediately reflect the change because it is also a live collection. Heres a simple example that creates a single images directory in the project folder: As described in the Apache Ant manual, the mkdir task will automatically create all necessary directories in the given path and will do nothing if the directory already exists. The following example demonstrates several forms of filtering, including token substitution using the CopySpec.expand(java.util.Map) method and another using CopySpec.filter(java.lang.Class) with an Ant filter: The filter() method has two variants, which behave differently: one takes a FilterReader and is designed to work with Ant filters, such as ReplaceTokens, one takes a closure or Transformer that defines the transformation for each line of the source file. For example, imagine collection in the above example gains an extra file or two after union is created. Step-by-step lessons on how to use Gradle, both in general and for specific tasks. Alternatively, you can make use of the default archive name pattern provided by AbstractArchiveTask.getArchiveFileName(): [archiveBaseName]-[archiveAppendix]-[archiveVersion]-[archiveClassifier].[archiveExtension].
