:submodule:release stuck at unSnapshotVersion

[tonisives]

There is no error message when this happens. The task is just stuck and doesn't exit with error.

The problem for me was that I had grade.properties with the version property in the root project.

However, this file needs to be in the submodule's folder.

For future developers it might be helpful to have documentation about which files and where need to be located for the task to succeed in multi module environment.
