I just created a giter8 (https://github.com/n8han/giter8) template for a simple gradle project: https://github.com/matlockx/simple-gradle-java.g8 So you can use g8 matlockx/simple-gradle-java and a new project structure will be created locally.
I would like to know whether other templates are used or how you avoid duplicating build.gradle files when handling multiple git repos.
