Contents 1 Introduction 1. 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.

Very flexible. Some features may require a more recent version. 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. In this case, this declares that it uses the jCenter repository, and that there is a classpath dependency on a Maven artifact.The ability to execute the SonarQube analysis via a regular Gradle task makes it available anywhere Gradle is available developer build, CI server, etc. The Gradle build already has much of the information needed for SonarQube to successfully analyze a project.

By preconfiguring the analysis based on that information, the need for manual configuration is reduced significantly. Installation is automatic, but certain global properties should still be configured. Be aware that the scanner uses system properties so all properties should be prefixed by systemProp.

Assuming a local SonarQube server with out-of-the-box settings is up and running, no further configuration is required. Execute gradle sonarqube and wait until the build has completed, then open the web page indicated at the bottom of the console output.

You should now be able to browse the analysis results. To analyze a project hierarchy, apply the SonarQube plugin to the root project of the hierarchy.

Typically but not necessarily this will be the root project of the Gradle build. Information pertaining to the analysis as a whole has to be configured in the sonarqube block of this project. Any properties set on the command line also apply to this project. Project-specific information is configured in the sonarqube block of the corresponding project. All tasks that produce output that should be included in the SonarQube analysis need to be executed before the sonarqube task runs.

Typically, these are compile tasks, test tasks, and code coverage tasks. To meet these needs, the plugins adds a task dependency from sonarqube on test if the Java plugin is applied. Further task dependencies can be added as needed. For example:. The SonarScanner for Gradle uses information contained in Gradle's object model to provide smart defaults for most of the standard analysis parametersas listed below.

Notice that additional defaults are provided for projects that have the java-base or java plugin applied:.

In the main build. This works but I want to do add a sourceSet specific to productFlavor and the buildType like this:.

Which could be defined for each product flavor and per buildType, but this doesn't work when I try to add it dynamically. What works for me is this thanks to this answer How can I specify per flavor buildType sourceSets?

However I would really like this to be added dynamically, so I can still preserve my configuration file intact. I think I understand. I will say first off once again that this is not a great setup and you should really look to move towards a more standard setup.

So for the solution, in order to read flavor sources dynamically, I recommend moving your ext structure to something like this:. This lets you read the source paths and iterate over keys and values in project. The annoyance with doing this at the variant level is that you have to register the extra sources since the variant object at this point has already collected the sources from the source set and product flavors.

However, I think this is probably the least invasive way to do this dynamically. Learn more.

SonarScanner for Gradle

I'm still unclear on what you want here Also, you have an apply from a gradle file; what's in variants. Then where does javaDirRelease come from? I edited the answer a bit, so you have a better understanding of the variants.

The "add to sourceSet" was a semantic misunderstanding, I meant "set a sourceSet".GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

In a multi-module build, adding an output directory to the main sourceSet as explained in SourceSetOutput should work the same when using the java plugin or the java-library plugin. If the project in question is using the java-library plugin, only its classes directory is on the consumer's classpath as explained in the docsbut not any extra output directories registered on the main sourceSet.

This might also affect resources, since the resources directory is also not on the classpath of consumers. Of course. I saw that you use directories like "generated" in your sample though no code is actually generated. Is that relevant? Is code generated and then supposed to be on the compile classpath for the main source set? Please provide the relevant information and the code that you use to generate code if that's what you are trying to do. This is only a reproducer mostly taken from gradle documentation examples.

I tried to keep things as minimal as possible to highlight what I think is a bug, without going into details of why we run into this. The salient point for me is that it does work with the 'java' plugin, but this might be a conscious design choice. If so, I did not find it documented. But since you asked, this is what we are really doing that runs into this problem.

I'd welcome any suggestions for improvement. I hope this is clear enough, but I cannot provide much more details, especially not for the two ant tasks. I have the same problem in another subproject as well, now, where we need to compile parts of the code with an older target release:. If I use the 'java-library' plugin, the consumers cannot see the legacy classes and fail to compile. Without the second sourceSet, or with the 'java' plugin, all is well. Do you agree that this is a bug, or is this behaviour intended?

We are very sorry to announce that development of this plugin has been discontinued. Google has created their own Android development toolchain based on Gradle, which supercedes this plugin.

This is the Android plugin for the Gradle build system. This plugin enables the creation of Android applications using Gradle, with all of the power and flexibility you've come to expect from Gradle. The Android plugin fully integrates into the Gradle build lifecycle by extending the Java plugin. Furthermore, the incorporation of ProGuard into the build not only ensures that Android application packages are small and tight, it also trivially enables the use of Scala for Android application development simply by incorporating the existing Scala plugin into the build.

ProGuard will include only those classes from the Scala library that are actually used by your Android application, resulting in an application package that is as small as possible. To use the Android plugin for Gradle you must first create the application skeleton using the android command-line tool.

For example:. This will create and Android application skeleton that you can immediately build using Ant. To build with Gradle instead, you must 1 create a build.

Create a build. The android create project command created the source code directly in the src directory of the project. The Android plugin tries to conform to the conventions established by Android's Ant-based build, but in this case it is better to conform to Gradle's "source sets" convention, since it allows you to have separate test source code, or to use multiple languages. However, if you prefer to keep your source code directly in the src directory for example, if you need to retain compatibility with Ant then you can do so by configuring the Java source set in your build.

Just add the following to build. If your Android project was initially created by Eclipse rather than the android create project command, then you will have some additional setup work to do. When you create a project with the android create project command, the location is filled in for you by the application generator, but the Eclipse project generator does not provide this information to the project.

Therefore, you must fill it in yourself. To do this, create or edit the local. Note that this file should not be checked in to your version control system as it will likely differ across various development environments. Once you've performed these steps you can build your Android application by invoking the tasks described above. This build script configures the build to sign with a provided keystore. This configuration applies for every build 1. It also sets Gradle to expand properties in every resource file 2.

It processes all the resources, expanding them with properties from the project's scope, compiles classes, packs them into the dex file, builds the apk, signs it with the provided keystore but does not process it with proguard and zipaligns the package, which is named -x.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I want to add integration tests to my Gradle build Version 1. They should run separately from my normal tests because they require a webapp to be deployed to localhost they test that webapp. The tests should be able to use classes defined in my main source set. How do I make this happen? This took me a while to figure out and the online resources weren't great.

So I wanted to document my solution. This is a simple gradle build script that has an intTest source set in addition to the main and test source sets:. This was once written for Gradle 2. Please have a look at the documented solutions in Gradle 4 and up.

Configure the integrationTest test classes and classpaths use. The defaults from the java plugin use the test sourceSet. Unfortunatly, the example code on github. The nebula-facet plugin eliminates the boilerplate:. For integration tests specifically, even this is done for youjust apply:.

As of version 4. So if your build script uses sourceSets. Gradle now uses separate output directories for each JVM language, but this build assumes a single directory for all classes from a source set. This behaviour has been deprecated and is scheduled to be removed in Gradle 5. To get rid of this warning, just switch to sourceSets. For more information, see the Gradle 4. I'm new to Gradle, using Gradle 6. Here's what I came up with to solve this problem.

Notice that the main source and test source is referenced separately, one under main and one under test. The testImplementation item under dependencies is only used for compiling the source in test. If your main code actually had a dependency on JUnit, then you would also specify implementation under dependencies. Learn more. How do I add a new sourceset to Gradle? Ask Question.

You'll still need to declare and configure an integration test task. Thanks PeterNiederwieser I've corrected my sample build script.This page builds on the Configure your build overview to show you how you can configure build variants to create different versions of your app from a single project, and how to properly manage your dependencies and signing configurations.

Each build variant represents a different version of your app that you can build. For example, you might want to build one version of your app that's free, with a limited set of content, and another paid version that includes more. You can also build different versions of your app that target different devices, based on API level or other device variations. However, if you want to build different versions based on the device ABI or screen density, instead build multiple APKs. Build variants are the result of Gradle using a specific set of rules to combine settings, code, and resources configured in your build types and product flavors.

gradle sourcesets

Although you do not configure build variants directly, you do configure the build types and product flavors that form them. For example, a "demo" product flavor can specify different features and device requirements, such as custom source code, resources, and minimum API levels, while the "debug" build type applies different build and packaging settings, such as debug options and signing keys.

You can create and configure build types in the module-level build. When you create a new module, Android Studio automatically creates the debug and release build types for you. Although the debug build type doesn't appear in the build configuration file, Android Studio configures it with debuggable true.

This allows you to debug the app on secure Android devices and configures APK signing with a generic debug keystore. You can add the debug build type to your configuration if you want to add or change certain settings. The following sample specifies an applicationIdSuffix for the debug build type, and configures a "staging" build type that is initialized using settings from the debug build type.

Note: When you make changes to a build configuration file, Android Studio requires that you sync your project with the new configuration.

To sync your project, you can click Sync Now in the notification bar that appears as soon as you make a change or Sync Project from the toolbar. If Android Studio notices any errors with your configuration, the Messages window appears to describe the issue. To learn more about all the properties you can configure with build types, read the build type DSL reference. Creating product flavors is similar to creating build types: add them to the productFlavors block in your build configuration and include the settings you want.

The product flavors support the same properties as defaultConfig —this is because defaultConfig actually belongs to the ProductFlavor class. This means you can provide the base configuration for all flavors in the defaultConfig block, and each flavor can change any of these default values, such as the applicationId. You must also use that package name in your source code to refer to the R class, or resolve any relative activity or service registration.

This allows you to use applicationId to give each product flavor a unique ID for packaging and distribution, without having to change your source code.

All flavors must belong to a named flavor dimension, which is a group of product flavors.

You must assign all flavors to a flavor dimension; otherwise, you will get the build error shown below. If a given module specifies only one flavor dimension, the Android Gradle plugin automatically assigns all of the module's flavors to that dimension.

The following code sample creates a flavor dimension named "version" and adds "demo" and "full" product flavors. These flavors provide their own applicationIdSuffix and versionNameSuffix :. To distribute different variants of your app as separate apps in Google Play, you need to assign a different applicationId to each variant. After you create and configure your product flavors, click Sync Now in the notification bar.

For example, if you created "demo" and "full" product flavors, and kept the default "debug" and "release" build types, Gradle creates the following build variants:.

To start customizing each build variant with its own features and resources, however, you'll need to know how to create and manage source sets. In some cases, you may want to combine configurations from multiple product flavors. For example, you may want to create different configurations for the "full" and "demo" product flavors that are based on API level.
