Gradle Plugin User Guide Android Studio Project Site.Introduction. DSL reference.If you are looking for a full list of options available in build.DSL reference. Goals of the new Build System.The goals of the new build system are Make it easy to reuse code and resources.Make it easy to create several variants of an application, either for multi apk distribution or for different flavors of an application.Make it easy to configure, extend and customize the build process.Good IDE integration.Gradle is an advanced build system as well as an advanced build toolkit allowing to create custom build logic through plugins.Here are some of its features that made us choose Gradle Domain Specific Language DSL based on Groovy, used to describe and manipulate the build logic.Build files are Groovy based and allow mixing of declarative elements through the DSL and using code to manipulate the DSL elements to provide custom logic.Built in dependency management through Maven andor Ivy.Very flexible. Allows using best practices but doesnt force its own way of doing things.Plugins can expose their own DSL and their own API for build files to use.Good Tooling API allowing IDE integration.Requirements. Gradle 2.SDK with Build Tools 1.But after President Donald J.Trump looked directly at the partial eclipse despite the repeated exhortations of his aides on Monday, staring at eclipses is not only.Some features may require a more recent version.Basic Project Setup.A Gradle project describes its build in a file called build.See Gradle User Guide for an overview of the build system itself.Simple build files.The most simple Android project has the following build.Sdk. Version 2. 3 build.HH010.png' alt='Groovy Eclipse Plugin Manual Installation' title='Groovy Eclipse Plugin Manual Installation' />Activiti development can be done with the IDE of your choice.If you would like to use the Activiti Designer then you need Eclipse Kepler or Luna.Date Change 06th Jan 2014 First Draft Published 07th Jan 2014 Fixed typos 12th Feb 2014 Added IntelliJ for Eclipse Users.Tools. Version 2.There are 3 main areas to this Android build file buildscript.In this case, this declares that it uses the j.Center repository, and that there is a classpath dependency on a Maven artifact.This artifact is the library that contains the Android plugin for Gradle in version 1.Note This only affects the code running the build, not the project.The project itself needs to declare its own repositories and dependencies.This will be covered later.Then, the com. android.This is the plugin used for building Android applications.Finally, android.Groovy/img/xdownloadgroovycommandline.png.pagespeed.ic.HsaZ_Zu2aF.png' alt='Groovy Eclipse Plugin Manual Installation' title='Groovy Eclipse Plugin Manual Installation' />This is the entry point for the Android DSL. Bio Rad Biologic Duoflow Software Development there. By default, only the compilation target, and the version of the build tools are needed.This is done with the compile.Sdk. Version and buildtools.Version properties.The compilation target is the same as the target property in the project.This new property can either be assigned a int the api level or a string with the same value as the previous target property.Important You should only apply the com.Applying the java plugin as well will result in a build error.Note You will also need a local.SDK in the same way that the existing SDK requires, using the sdk.Alternatively, you can set an environment variable called ANDROIDHOME.There is no differences between the two methods, you can use the one you prefer.Example local. properties file sdk.AndroidSdk. The basic build files above expects a default folder structure.Gradle follows the concept of convention over configuration, providing sensible default option values when possible.The basic project starts with two components called source sets, one for the main source code and one for the test code.These live respectively in srcmainsrcandroid.TestInside each of these directories there are subdirectories for each source component.For both the Java and Android plugin, the location of the Java source code and the Java resources are For the Android plugin, extra files and folders specific to Android Android.Manifest. xmlresassetsaidlrsjnijni.LibsThis means that.Android. Manifest.Note srcandroid. TestAndroid.Manifest. Configuring the Structure.When the default project structure isnt adequate, it is possible to configure it.See this page in gradle documentation for information how this can be done for pure java projects.The Android plugin uses a similar syntax, but because it uses its own source.Sets, this is done within the android block.Heres an example, using the old project structure used in Eclipse for the main code and remapping the android.Testsource. Set to the tests folder android source.Sets main manifest.File Android. Manifest.Dirs src resources.Dirs src aidl.Dirs src renderscript.Dirs src res.Dirs res assets.Dirs assets android.Test. set. Roottests Note because the old structure put all source files Java, AIDL and Render.Script in the same folder, we need to remap all those new components of the source.Set to the same src folder.Note set. Root moves the whole source.Set and its sub folders to a new folder.This moves srcandroid.Testto testsThis is Android specific and will not work on Java source.Sets. Applying a plugin to the build file automatically creates a set of build tasks to run.Both the Java plugin and the Android plugin do this.The convention for tasks is the following assemble.The task to assemble the outputs of the project.The task to run all the checks.This task does both assemble and check.This task cleans the output of the project.The tasks assemble, check and build dont actually do anything.They are anchor tasks for the plugins to add dependent tasks that actually do the work.This allows you to always call the same tasks no matter what the type of project is, or what plugins are applied.For instance, applying the findbugs plugin will create a new task and make check depend on it, making it be called whenever the check task is called.From the command line you can get the high level task running the following command For a full list and seeing dependencies between the tasks run Note Gradle automatically monitor the declared inputs and outputs of a task.Running the build task twice without making changes to your project, will make Gradle report all tasks as UP TO DATE, meaning no work was required.This allows tasks to properly depend on each other without requiring unnecessary build operations.Here are the two most important tasks created by the java plugin, dependencies of the main anchor tasks assemblejar.This task creates the output.This task runs the tests.The jar task itself will depend directly and indirectly on other tasks classes for instance will compile the Java code.The tests are compiled with test.Classes, but it is rarely useful to call this as test depends on it as well as classes.In general, you will probably only ever call assemble or check, and ignore the other tasks.You can see the full set of tasks and their descriptions for the Java plugin here.Android tasks. The Android plugin uses the same convention to stay compatible with other plugins, and adds an additional anchor task assemble.The task to assemble the outputs of the project.The task to run all the checks.Check. Runs checks that requires a connected device or emulator.Check. Runs checks using APIs to connect to remote devices.This is used on CI servers.This task does both assemble and checkclean.This task cleans the output of the project.The new anchor tasks are necessary in order to be able to run regular checks without needing a connected device.Note that build does not depend on device.Check, or connected.Check. An Android project has at least two outputs a debug APK and a release APK.Each of these has its own anchor task to facilitate building them separately assembleassemble.Debugassemble. Release.They both depend on other tasks that execute the multiple steps needed to build an APK.The assemble task depends on both, so calling it will build both APKs.Tip Gradle support camel case shortcuts for task names on the command line.For instance as long as no other task matches a.RThe check anchor tasks have their own dependencies checkconnected.Checkdevice. Check.This depends on tasks created when other plugins implement test extension points.Finally, the plugin creates tasks for installing and uninstalling all build types debug, release, test, as long as they can be installed which requires signing, e.Debuginstall. Releaseuninstall.Alluninstall. Debuguninstall.Releaseuninstall.Debug. Android. Test.Basic Build Customization.The Android plugin provides a broad DSL to customize most things directly from the build system.Manifest entries.Through the DSL it is possible to configure the most important manifest entries, like these min.Sdk. Versiontarget.
