android - Add dependency to specific productFlavor and buildType in gradle

Question

I'm wondering how to add dependency to specific productFlavor and buildType in gradle. For example I have productFlavor free and build type release, how can I add a dependency on the assembleFreeRelease task?

I've tried many variants but neither works.

For example I tried:

task('release', dependsOn: assembleProductionRelease) {
} 
// error: Could not find property 'assembleProductionRelease' on root project 'app'.

Or:

task('release', dependsOn: 'assembleProductionRelease') {
}

Here there is no error but the task is executed for every flavor and build type, very confusing.

Answer 1

There is built-in support for flavor and buildType dependencies.

dependencies {
   flavor1Compile "..."
   freeReleaseCompile "..."
}
