title: How to set global repositories for gradle that I can use them in each gradle project
body: <p>It's slow to visit the maven official repositories from my country, so I want to try some local repositories first.</p>
  
  <p>Is it able to add them to some global gradle configuration file, that I can just use them in each gradle project, without modifying the project-scope <code>build.gradle</code> file?</p>
