Gradle Custom Plugin: gradleApi() vs Explicit Depe

问题:

I'm developing a custom gradle plugin and the dependencies for my plugin project look like this:

dependencies {
  compile gradleApi()
  compile localGroovy()
  compile('com.xxx.oozie:oozie-dsl-parser:1.0.127') {
    exclude module: 'groovy-all'
  }

  testCompile('org.spockframework:spock-core:1.0-groovy-2.3') {
    exclude module: 'groovy-all'
  }
}

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.

Do you guys have any suggestions?

Thanks!

I suggest applying the java-gradle-plugin. It adds the gradleApi() dependency automatically and also includes some other boilerplate configurations: https://docs.gradle.org/current/userguide/javaGradle_plugin.html#gsc.tab=0

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 2.14.1 the used Gradle API will be of that version.

You also do not have to worry about localGroovy() because it is already included in the gradleTestKit() dependency which is added by the plugin: https://docs.gradle.org/current/userguide/test_kit.html#sub:test-kit-automatic-classpath-injection&gsc.tab=0

Here is an example:

apply plugin: 'groovy'
apply plugin: 'java-gradle-plugin'

dependencies {
    testCompile('org.spockframework:spock-core:1.0-groovy-2.4') {
        exclude module: 'groovy-all'
    }
}

Looking at https://github.com/gradle/gradle/issues/1835 it seems like there is no explicit dependency you can use for that purpose.

Although not equivalent to gradleApi(), if you are developing for Android you might be interested in the com.android.tools.build:gradle-api:3.3.2 dependency.
