Make an auto-fill repository based on the gradle-plugin instead of hard-coding it

I think it take alot of time to put each repository into the code to download all dependencies even there is a Gradle plugin for it. So basically, it should be a good approach to include the repositories (even it's a private with credentials) into the runtimeDownload.txt from GradleScript.

I'll consider this, but I don't think having exactly the same repositories during build time & runtime download is always desired.
