Referencing the outputs of a task in another project in Gradle

Question

Consider the following setup

rootProject
|--projectA
|--projectB

There is a task taskB in projectB and I would like the reference the outputs of that task in a copy task taskA in projectA. For example, taskA might look something like:

task taskA(type: Copy) {    
    dependsOn ':projectB:taskB'

    from ':projectB:taskB.outputs'

    into 'someFolder'
}

Of course the above example doesn't actually work. While it's okay to reference the task as :projectB:taskB as a dependency, :projectB:taskB.outputs doesn't seem to mean anything to Gradle. I've tried reading through the Gradle docs but didn't find anything that referenced what I'm trying to do.

Answer 1

projectA build.gradle should be:

evaluationDependsOn(':projectB')

task taskA(type:Copy, dependsOn:':projectB:taskB'){
    from tasks.getByPath(':projectB:taskB').outputs
    into 'someFolder'
}
