A new repository for Scala nightlies

A new Scala blog post/announcement has been posted!

Recently, we introduced a new repository to which nightlies of Scala will be published. From now on, the place to look for nightly versions will be https://repo.scala-lang.org/. This also applies to nightly versions published before the change.

Both Scala 2 and Scala 3 nightly versions are available on the new repository.

Why was the change made?

As a result of a number of features to be delivered in Scala 3.8, chief among them the standard library built with Scala 3, the size of the average Scala 3 release has increased considerably. Based on that fact, we have decided it is no longer suitable to publish them to Maven Central alongside stable releases, and a dedicated hosting space should be used instead.

What exactly was changed?

Under the hood, it is only Scala 3 nightlies which are now published to a new repository. They used to be published to Maven Central until 3.8.0-RC1-bin-20250822-658c8bd-NIGHTLY (or until the 23rd of August, 2025). All versions that followed have been published to https://repo.scala-lang.org/. Versions from before the change are still available on https://repo.scala-lang.org/, which also serves as a proxy to Maven Central.

At the time of writing of this blog post, only Scala 3.8 nightlies are published directly to the new repository. The change is planned to be backported to Scala 3.3 LTS.

Scala 2 nightlies have been published to a dedicated repository for a long time and this, in fact, did not and likely will not change. The new repository does, however, serve as a proxy to the Scala 2 ni...
