Call parent function from subproject

Question

Is there way in Gradle how to call parent function from subproject? If I have parent project and function defined as:

def testMethod() {
    println("TestMethod called from directory ${project.projectDir}")
}

and subproject as:

task subTest << {
    println("I'm subTest task from ${project.projectDir}")
    testMethod()
}

calling this from commandline results in:

Could not find method testMethod() for arguments [] on root project 'subsys1'

Answer 1

Could not find method testMethod() for arguments [] on root project 'subsys1'

Means that Gradle thinks that subsy1 is the root project, whereas your parent project should be the root project. This means that you have more than 1 settings.gradle, and it thinks that subsys1 is the start of the project hierarchy. There should only be 1 settings.gradle file, which should reside in the root project. There you configure each of the subprojects. They don't get their own settings.gradle files.
