Add build dependencies

However, in the interest of reproducible builds, I'm wondering if using localGroovy and gradleApi is advisable. After much googling, although I could replace localGroovy with a specific version of groovy, I can't seem to find a definitive answer on what I would replace gradleApi with.

I suggest applying the java-gradle-plugin. The version of the gradleApi that is added as dependency depends on the Gradle version that you are using the build the project. For example if your wrapper has Gradle 2. Although not equivalent to gradleApiif you are developing for Android you might be interested in the com.

The Unfriendly Robot: Automatically flagging unwelcoming comments. Featured on Meta.The Gradle build system in Android Studio makes it easy to include external binaries or other library modules to your build as dependencies.

The dependencies can be located on your machine or in a remote repository, and any transitive dependencies they declare are automatically included as well. This page describes how to use dependencies with your Android project, including details about behaviors and configurations that are specific to the Android plugin for Gradle.

For a deeper conceptual guide to Gradle dependencies, you should also see the Gradle guide for dependency management —but remember that your Android project must use only the dependency configurations defined on this page.

To add a dependency to your project, specify a dependency configuration such as implementation in the dependencies block of your build. For example, the following build. This declares a dependency on an Android library module named "mylibrary" this name must match the library name defined with an include: in your settings. When you build your app, the build system compiles the library module and packages the resulting compiled contents in the APK.

This declares a dependency on version Note: Remote dependencies like this require that you declare the appropriate remote repositories where Gradle should look for the library. If the library does not already exist locally, Gradle pulls it from the remote site when the build requires it such as when you click Sync Project with Gradle Files or when you run a build. Inside the dependencies block, you can declare a library dependency using one of several different dependency configurations such as implementation shown above.

Each dependency configuration provides Gradle with different instructions about how to use the dependency. The following table describes each of the configurations you can use for a dependency in your Android project. The table also compares these configurations to those that were deprecated as of Android Gradle Plugin 3. New configuration Deprecated configuration Behavior implementation compile Gradle adds the dependency to the compile classpath and packages the dependency to the build output.

However, when your module configures an implementation dependency, it's letting Gradle know that you do not want the module to leak the dependency to other modules at compile time. That is, the dependency is available to other modules only at runtime. Using this dependency configuration instead of api or compile deprecated can result in significant build time improvements because it reduces the number of modules that the build system needs to recompile.

For example, if an implementation dependency changes its API, Gradle recompiles only that dependency and the modules that directly depend on it. Most app and test modules should use this configuration. This configuration behaves just like compile which is now deprecatedbut you should use it with caution and only with dependencies that you need to transitively export to other upstream consumers.

That's because, if an api dependency changes its external API, Gradle recompiles all modules that have access to that dependency at compile time. So, having a large number of api dependencies can significantly increase build time.

Unless you want to expose a dependency's API to a separate module, library modules should instead use implementation dependencies. If you use this configuration, then your library module must include a runtime condition to check whether the dependency is available, and then gracefully change its behavior so it can still function if it's not provided. This helps reduce the size of the final APK by not adding transient dependencies that aren't critical.

This configuration behaves just like provided which is now deprecated. Note: When using Android Gradle plugin 3. To include lint check dependencies in your AAR libraries, use the lintPublish configuration described below. The above configurations apply dependencies to all build variants.

If you instead want to declare a dependency for only a specific build variant source set or for a testing source setyou must capitalize the configuration name and prefix it with the name of the build variant or testing source set. For example, to add an implementation dependency only to your "free" product flavor using a remote binary dependencyit looks like this:.

However, if you want to add a dependency for a variant that combines a product flavor and a build type, then you must initialize the configuration name in the configurations block. The following sample adds a runtimeOnly dependency to your "freeDebug" build variant using a local binary dependency :.

To add implementation dependencies for your local tests and instrumented testsit looks like this:.

However, certain configurations don't make sense in this situation. For example, because other modules can't depend on androidTestyou get the following warning if you use the androidTestApi configuration:.

If I need to compile against Gradle 3. I can use TestKit to verify compatibility with older versions, but it would be nice to get compile errors if I was using an API that was too new.

Ultimately, I don't understand the case for gradleApi being a special case dependency. Seems like it would be more straightforward to publish the Gradle API to a Maven repo like any other dependency in the Java community. This could be somewhat addressed with the epic It will likely require splitting up Gradle core into modules and publishing them.

I also agree with not understanding why gradleApi is a special case dependency. It seems like it should be something that akin to the provided scope in Maven. I would like to make sure it can be built and used against multiple Gradle versions and getting feedback during compilation time without having to write a bunch of Test Kit tests. It is even more a problem if I am using a build. We currently build the plugin using Gradle 4. Being able to build with and up-to-date version of Gradle but compile against the 4.

I want to be able to write an adapter for spotless that can selectively use the old task API or the new task API depending upon what version the plugin is running in. Skip to content.

To understand the limitations of the old Gradle plugin 2. All of its consuming modules will be left untouched.

When the external interface of a module changes however, also the modules consuming that module directly need to be recompiled. But those modules could be exposing parts of the bottom module directly through their own interface!

So to be completely safe, they would also need to be recompiled. Same for the ones using those… and those… and…. Now we do have a big problem: one code change causes all modules to be recompiled. Based on that it can make the right choice on what it should recompile. As such the compile dependency has been deprecated and replaced by two new ones:.

So now you can explicitly tell Gradle to recompile a module if the interface of a used module changes or not.

In theory you can simply replace all compile dependencies with api dependencies, but that would still cause everything to be recompiled:. So better approach is to replace all compile dependencies with implementation dependencies. That should cause a lot less recompilation. Hopefully, this clarifies the ambiguity between api and implementationas the official migration guide is quite cryptic.

As there was already a breaking change, the team also made use of the opportunity to finally give the other configurations proper names:. Just like before you can also combine these with your build variants: debugApitestImplementation ,…. Android Studio 3. My favorites are:. For more information have a look at the complete migration guide.

Always try to use the implementation dependency as this will cause fewer modules to be recompiled. As always you can reach me molsjeroen on Twitter, or leave a comment below!

Test to write tests and extensions and junit-jupiter-engine has test engine implementation which is required at runtime to execute the tests.

Internally, junit-jupiter-engine is dependent on junit-jupiter-apiso adding junit-jupiter-engine only brings both dependencies into classpath. We can learn about internal dependencies between various junit jars in this image. We will need junit-platform-runner for executing tests and test suites on the JUnit Platform in a JUnit 4 environment.

Internally, junit-platform-runner is dependent on junit-platform-suite-api and junit-platform-launcherso adding junit-jupiter-engine only brings all three dependencies into classpath. To execute junit 4 tests in junit 5 environmentyou will need to include junit-vintage-engine dependency.

I tried using the 'api' dependency keyword in my projectbut I got this error saying it cannot find method api. The api configuration comes from the java-library plugin, in your build script you have just applied java plugin. The key difference between the standard Java plugin and the Java Library plugin is that the latter introduces the concept of an API exposed to consumers.

A library is a Java component meant to be consumed by other components. Just apply the java-library plugin which extends java plugin and it should work:. Learn more. How to use gradle 'api' dependency Ask Question.
