Publish the index to Maven Central again?

[alexarchambault]

The index used to be published to Maven Central, see here.

It might be interesting to do that again, to work around GitHub outages.

See com-lihaoyi/mill#3716 for context

@alexarchambault any updates here? We need this to unblock com-lihaoyi/mill#3716

[alexarchambault]

@lihaoyi The new indices are automatically published since #297

I have to cut a new release of coursier that includes coursier/coursier#3127 and coursier/coursier#3128, in order to allow using the new index. Will do it in the afternoon, Europe time, in order to get a few more PRs in.

Fixed by #297

[lihaoyi]

ok thanks!

FYI, I'm having issues cutting a new coursier release. Publishing with Mill now requires Java >= 11. I'd like to keep supporting Java 8, so --release 8 needs to be passed to scalac, but this breaks access to unsupported JDK APIs (sun.misc.{Signal, SignalHandler} here). Just stumbled upon scala/bug#13015 that has a workaround, I should be able to give it a try, but only in a few hours

@alexarchambault you could use mill 0.11.12 if you want to use Java 8 i think, that should have gotten the publishign fix without the java version bump

[alexarchambault]

@lihaoyi That could have worked, yes. OTOH, it's nice to decouple the local JVM and the targeted one, so that we don't mistakenly bump the required JVM version.
