Many of these plugins provide sensible conventions for the names of archives as well as the copy specifications used. For example, the Java plugin adds a jar task for packaging a projects compiled classes and resources in a JAR. These can be used and manipulated in exactly the same way as the file trees you create yourself. It works the same way as the Copy task by configuring it with a copy spec. There is no way at the moment to force the working dir of gradle process. the reason was default gradle repos sanctions against the country I live in so android builds would fail due to limitations applied. There are two common issues people come across when using regular expressions in this context: If you use a slashy string (those delimited by '/') for the first argument, you must include the parentheses for rename() as shown in the above example. Gradle builds on the standard Java File class, which represents the location of a single file, and provides new APIs for dealing with collections of paths. Problem is like #18 that netbeans gradle plugin should start "process" in project root directory, but for me it's still using c:\program files\netbeans instead. For example, the following task deletes the entire contents of a builds output directory: If you want more control over which files are deleted, you cant use inclusions and exclusions in the same way as for copying files. The following example does just that to clear out temporary files from a source directory: Youll learn more about file collections and file trees in the next section. Since you are deploying a single file, the destination directory of the Copy is the whole deployment directory. > Could not create service of type FileHasher using BuildSessionServices.createFileHasher(). What is the function of in ? gradle properties Solution 2 Overall, the anatomy of a typical project root directory looks roughly as follows: From version 4.10 onwards, Gradle automatically cleans the project-specific cache directory. When you are building a standalone executable, you may want to install this file on your system, so it ends up in your path. 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. The version portion of the archive file name, typically in the form of a normal project or product version. The executable implicitly looks for files with a particular extension in the working directory. Additionally, we might not want to copy any empty folder such as images or js to the war file. You do this by adding an into() declaration for just the PDFs: As you can see, you can have multiple from() declarations in a copy specification, each with its own configuration. A file collection is simply a set of file paths thats represented by the FileCollection interface. Thanks for contributing an answer to Stack Overflow! And then we need to build our applications to download all their dependencies, otherwise, we will fail when we try using the offline mode. Making statements based on opinion; back them up with references or personal experience. When the migration is complete, you will access your Teams at stackoverflowteams.com, and they will no longer appear in the left sidebar on stackoverflow.com. To learn more, see our tips on writing great answers. Sorted by: 36. If you want to apply filtering to a subset of the copied files, youll need to use child specifications. You can pass in property names and values that are then expanded in the source files. Its generally preferable to copy directories and files instead. This is formally based on the CopySpec interface, which the Copy task implements, and offers: A CopySpec.from(java.lang.Object) method to define what to copy, An CopySpec.into(java.lang.Object) method to define the destination. Gradle Wrapper. Youve alread seen many examples in the form of configuration for Copy and archiving tasks. Method #3: Download and configure Gradle: Simply Go to the Android Studio plugins Path and look for a file named gradle-wrapper-x.xx.jar (x.xx = version number). They all share most of the configuration options of Copy, including filtering and renaming. 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. 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. Manually creating a directory, Example 15. Note that both variants assume the source files are text based. 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. Example 16.1. If you need to change the JDK by some reason, you can set the JDK home with Java toolchains or the Task DSL to set a local JDK.. we have many users not using gradle so we do not want to check it into the source code (yet? 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. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, can it be done with some env variable? Normally, we strongly recommend that your build.gradle should not depend on the working dir. how do we set the working directory in a standard way, i.e. However, the directory itself is not included in the copy. Here we use a string pattern to include PDFs only: One thing to note, as demonstrated in the following diagram, is that only the PDFs that reside directly in the reports directory are copied: You can include files in subdirectories by using an Ant-style glob pattern (**/*), as done in this updated example: One thing to bear in mind is that a deep filter like this has the side effect of copying the directory structure below reports as well as the files. This will create a tree of all the files and directories in that base directory (but not the base directory itself). This is the default behavior when you specify a directory as the from() argument, as demonstrated by the following example that copies everything in the reports directory, including all its subdirectories, to the destination: The key aspect that users struggle with is controlling how much of the directory structure goes to the destination. Under System Variables select Path, then click Edit. Defining all of your files this way makes your build agnostic to the working dir of the JVM. Relative paths are resolved relative to the project directory, while absolute paths remain unchanged. All core Gradle tasks ensure that any output directories they need are created if necessary using this mechanism. The Gradle user home directory ($USER_HOME/.gradle by default) is used to store global configuration properties and initialization scripts as well as caches and log files. Parameters: path - The path provider. So we need separate filter patterns for those two sets of files. Filtering files as they are copied, Figure 4. The base name portion of the archive file name, typically a project name or some other descriptive name for what it contains. 2 comments Closed . An archive is a directory and file hierarchy packed into a single file. You can put the following line in your build script: Or in gradle.properties file (no quotes around your_directory in that case). The following steps are typical for creating a custom Gradle distribution: Implement logic for downloading and repackaging a Gradle distribution. 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. Gradle can make no guarantees about the location of the CWD, which means builds that rely on it may break at any time. This allows you to create a copy spec outside of a task, which can then be attached to an appropriate task using the CopySpec.with(org.gradle.api.file.CopySpec) method. In addition, this example could be improved further by relying on the Java plugins convention for destinationDirectory rather than overriding it, but it does demonstrate the use of project properties. Using Copy to deploy a WAR file, Example 44. From my reading of the docs simply doing gradle run -PworkingDir= should do the trick, but it doesn't work the working dir is still the project dir. 37 comments veita commented on Nov 29, 2016 git clone git://git.apache.org/groovy.git cd groovy Check out commit 273c15375bb8ab03e9ac17a13818bef69491dc9c if necessary. You can easily delete files and directories using either the Delete task or the Project.delete(org.gradle.api.Action) method. 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. The main convention is provided by the Base Plugin, which defaults to creating archives in the $buildDir/distributions directory and typically uses archive names of the form [projectName]-[version].[type]. The same goes for the different file collection. Here, the integrationTest compilation is associated with the main compilation that gives access to internal objects from functional tests.. Set custom JDK home. [GRADLE-3438] Running gradle init from different working directory does not run maven conversion Created: 18/Apr/16 Updated: 13/May/16 Resolved: 18/Apr/16 Status: Resolved: Project: Gradle: Affects Version/s: . Do be aware that the closure will be executed for every file thats copied, so try to avoid expensive operations where possible. The obvious caveat of this is that you have to do this for debug as well and you may have to specify the working directory again for "Run Single" and "Debug Single" as well. Its safest to use single quotes for the second argument, otherwise you need to escape the '$' in group substitutions, i.e. System.getProperty(user.dir)) returns the directory passed with -b, and not the directory where gradle/java is started. Thanks for contributing an answer to Stack Overflow! Would it be illegal for me to act as a Civillian Traffic Enforcer? 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. You can also traverse file trees using the FileTree.visit(org.gradle.api.Action) method. In cases where you need to create a directory manually, you can use the Project.mkdir(java.lang.Object) method from within your build scripts or custom task implementations. An important feature of the resulting file collections is that they are live. When working with application servers, you can use a Copy task to deploy the application archive (e.g. This makes them easy to understand, but its not good practice for real builds. This is necessary for projects like reproducible-builds.org. But copy specs have two attributes that are worth covering in more detail: The first of these attributes allows you to share copy specs within a build. For example, you might need to extract different subtrees of the archive into different paths within the destination directory. It does not provide values for the other properties. 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. Archiving a directory as a ZIP, Example 10. Prepare Before going for the offline mode, we need to install Gradle first. A file tree is a file collection that retains the directory structure of the files it contains and has the type FileTree. Each type of archive has its own task type, the most common ones being Zip, Tar and Jar. The File#mkdirs () call is neccessary, since if the directories do not exist, the call to your system-dependent java executable will cause a error. Is a planet-sized magnet a good interstellar weapon? Example 3. This process is described in Cross-Project publications. Consider the aim: to copy the contents of other JAR files into the application JAR. In my last How-To - Build and run a Kotlin/Native application with Visual Studio Code on macOS I showed you how to setup, build, and run your first Kotlin/Native application using the barebone Kotlin/Native compiler inside Visual Studio Code (VSC). Implementing a file collection, Figure 3. The closure syntax for rename() is straightforward and can be used for any requirements that simple regular expressions cant handle. Its better to use a reliable, single source of truth, such as a task or shared project property. 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. So be careful where you place your configuration. For example, you can extract some or all of the files of an archive by copying its contents to some directory on the file system. What happens in the case of multi-project builds? File runningDir = new File ('build/run/') runningDir.mkdirs () tasks.run.workingDir = runningDir Check this thread for reference. The following task definition does the necessary work: Notice how the src/dist configuration has a nested inclusion specification: thats the child copy spec. Build directory is a project property. In both cases, you specify which files and directories to delete in a way supported by the Project.files(java.lang.Object) method. By entering your email, you agree to our Terms and Privacy Policy, including receipt of emails. The following example demonstrates how this is done: Both the copyAssets and distApp tasks will process the static resources under src/main/webapp, as specified by webAssetsSpec. Read the in-depth sections later in the chapter for more detail on how the file operations work in Gradle and what options you have for configuring them. Out of the box, Gradle supports creation of both ZIP and TAR archives, and by extension Javas JAR, WAR and EAR formats Javas archive formats are all ZIPs. How do I tell gradle run to use a custom working directory? Creating a Java uber or fat JAR, Example 14. As described earlier, you can use the Project.copySpec(org.gradle.api.Action) method to share content between archives. "\$1\$2". We look at those next. dir Provider < Directory > dir ( Provider <? You can unsubscribe at any time. Verify your installation Not the answer you're looking for? The answer is the latter. Here you can find project-based topical guides to help you learn Gradle through using it. Chapter 16. This returns a relative path to the working directory. In this tutorial, we'll learn about Gradle Wrapper, an accompanying utility that makes it easier to distribute projects. You can learn more about this in the section on child specifications. Activating reproducible archives, 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, FileCollection.filter(org.gradle.api.specs.Spec), Understanding implicit conversion to file collections, Filtering file content (token substitution, templating, etc. Need a simple way to set working directory for Run and Debug, Making location easier for developers with new data primitives, Stop requiring only one assertion per unit test: Multiple assertions are fine, Mobile app infrastructure being decommissioned. To reliably execute Gradle from any subdirectory, it is necessary to set the "current project directory" via -p. It would be nice to have this restriction lifted (this would make a good feature request). That is why the copy() method is intended for use by custom tasks that need to copy files as part of their function. Most builds work with files. Here are the basic rules: If there are no explicit inclusions or exclusions, everything is included, If at least one inclusion is specified, only files and directories matching the patterns are included, Any exclusion pattern overrides any inclusions, so if a file or directory matches at least one exclusion pattern, it wont be included, regardless of the inclusion patterns. The effect of a flat filter on copying, Figure 2. Copying files using the copy() method without up-to-date check, Example 41. However, if our installed version doesn't match with the project's version, we'll probably face many incompatibility problems. Relevant logs and/or screenshots Live collections are also important when it comes to filtering. The Maven2Gradle conversion relies on the fact that Gradle is invoked within the maven project folder.
