Scala 3 Community Build

This project contains tests to build and test a corpus of open sources Scala projects against the latest version of Scala 3.

Running it locally

To run the community build on a local machine, first fetch all the git submodules with git submodule update --init and run sbt community-build/test from the root of the dotty repo.

To run a single project, you can use the usual syntax for running a single JUnit test, for example community-build/testOnly -- *shapeless
