I don't know which documentation do you miss. Gradle has pretty extensive documentation, stackoverflow has all kinds of answers and other websites have plenty of tutorials.
I don't know Groovy and I was able to write complicated enough multi-project builds with some custom build steps by copy-pasting snippets from the Internet and applying some common sense. I guess, Groovy knowledge is required if you need to write build plugins.
