Gradle. How to generate source code before compilation in android app

Question

In my android application I need to generate source code and use it in the app.
For that I created task genSources (using tutorials) for source generati

Answer 1

With gradle 2.2+ this should work:

tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn genSources
}

If you also want it to happen when you evaluate (e.g. when syncing your project with gradle in android studio) you can do it like this:

gradle.projectsEvaluated {
    preBuild.dependsOn genSources
}
