Upgrading fda2a1cf1e/gradle.properties (L7) to 1.17+build.5 fixed it.

Are you sure it didn't just fail to prepare the remapped mc jar?

Yes. A fresh clone did not build multiple times just a couple minutes ago.

However I just tried again and it appears to build just fine now. Odd...

A fresh clone doesn't reset everything since loom puts relevant data in ~/.gradle/caches/fabric-loom - you'd have to run gradle with --refresh-dependencies I think.

This appears to have been the issue for me. I retract all my statements, fresh clone and clearing ~/.gradle works just fine.

Clearing gradle, running with --refresh-dependencies, then running gradlew genSources before I build did the trick for me
