typelevel/download-java action for JVMs

[armanbilge]

Currently, sbt-gh-actions works with JVMs supported natively by actions/setup-java plus GraalVM via DeLaGuardo/setup-graalvm.

I'd like to propose switching to sdkman/sdkman-action for GraalVM and other "alternate" JVMs.

1. It supports an impressive amount of JVMs, see output of sdk list java below.
2. It directly integrates with actions/setup-java by spitting out a jdkFile that is consumed by setup-java, and thus all the actual installation/setup is done by setup-java.
3. The bus factor is almost definitely higher, and SDKMAN is "recognized" by Scala itself: Automate releases to SDKMAN scala/scala3#13885

Pinging @vasilmkd for his thoughts.

I am in favor of switching completely to sdkman, for all JDKs.

[rossabaker]

Would that retire the jdk-index project then?

[vasilmkd]

It's already not used by sbt-github-actions anymore.

I am in favor of switching completely to sdkman, for all JDKs.

Do you mean even for the ones natively support by actions/setup-java? I think those are specially cached in the GH runners.

[armanbilge]

Update on this: @vasilmkd and I decided to go in a different direction. We've created our own GH action typelevel/download-java that integrates Vasil's jdk-index with the official actions/setup-java.

It's essentially a tiny bash script that looks up a JDK in the index, downloads it, then points setup-java at that file for installation. This gives us full capability to keep everything up-to-date and offer JVMs that are not provided by setup-java such as GraalVM and Amazon Corretto.

This will be how we manage JDKs in sbt-typelevel.
