Execute gradle task on sub projects

Question

I have a MultiModule gradle project that I am trying to configure.

Root
    projA
    projB
    other
        projC
        projD
        projE
        ...         


        

Answer 1

I found this question today because I have the same issue. All of the ways mentioned by Mark can be used but all of them have some cons. So I am adding one more option:

4. Switching the current project

gradle -p other hello

This switches the "current project" and then runs all tasks named hello under the current project.
