build a corpus of open-source repos against nightly Scala builds

Scala Community Build

This repository contains configuration files that enable us to build and test a corpus of Scala open source projects together using Lightbend's dbuild. This project is financed and primarily maintained by Lightbend, as part of our overall maintenance of the Scala compiler and standard library.

How big is it? It's 3.2 million lines of Scala code, total, from 185 projects (as of January 2019), and takes about 15 hours to run.

Why do this? The main goal is to guard against regressions in new versions of Scala (language, standard library, and modules), as a complement to the regression test suite that we maintain in scala/scala. It's also a service to the open source community, providing early notice of issues and incompatibilities.

Can I run it myself? Sure, just clone the repo and run ./run.sh.
