Hi, I'm trying to use nvim-metals for a Scala project that requires a minimum Maven version of 3.8.8. MetalsImportBuild fails with the following error message:

It seems mavenScript is not being picked up. What am I doing wrong?

I can work around the issue by changing the minimum Maven version required in pom.xml, but I just want to know the right way to change the settings.

Hey @clee704 is your project open source by chance that I could test with? My guess is that this is an error with https://github.com/scalacenter/bloop-maven-plugin not accounting for that version of Maven.

[clee704]

@ckipp01 It's Apache Spark (v3.5.1) https://github.com/apache/spark/tree/v3.5.1

[ckipp01]

So playing around with this it seems that indeed it's an issue with the Bloop plugin not supporting that version of Mvn. Can you create an issue in https://github.com/scalacenter/bloop-maven-plugin for this?
