You can edit .github/workflows/ci.yaml, but if you tested it manually that should be good enough

I'm not sure I understand what changed and why the change was necessary, can you write a more detailed commit message, and add a documentaiton comment above common?

Looks like a transient failure in the community build:

2020-05-22T19:45:43.8077306Z curl: (22) The requested URL returned error: 500 Internal Server Error
2020-05-22T19:45:43.8252465Z [error] Test dotty.communitybuild.CommunityBuildTest.sourcecode failed: java.lang.AssertionError:

@anatoliykmetyuk It looks like sourcecode is downloading stuff (mill itself?) in the community build and this isn't cached, that might explain some of the network consumption reported by Fabien if all the mill projects do this.
