Server-only minecraft jar option no longer working in Loom 1.4

[LCLPYT]

Gradle builds using loom { serverOnlyMinecraftJar() } fail when using fabric-loom 1.4-SNAPSHOT. The following error is reported by gradle:

Could not resolve: net.minecraft:minecraft-SERVEROnly-1f338b2c9f:1.20.2-net.fabricmc.yarn.1_20_2.1.20.2+build.1-v2

Replicate the issue

• checkout fabric-example-mod
• replace the loom section in the gradle buildscript with:

  
  loom {

• splitEnvironmentSourceSets()
• mods {
• "modid" {
• sourceSet sourceSets.main
• sourceSet sourceSets.client
• }
• }
• serverOnlyMinecraftJar() }

• sync gradle (e.g. ./gradlew build or ide sync button)

I suspect it's caused by the removal of toLowerCase here: https://github.com/FabricMC/fabric-loom/commit/b7c80133ce9e6f13ced8ee2634f2f62690eff2e9#diff-1e4991838a7f4686fcba0a054df51f611a025eefaf3c9458f020d69b8c68add6L139-R130

I have reverted the fix for this, as it started causing the same issue for all existing projects. I think this happens becuae LocalMavenHelper is not case sensitive, but the maven resolver is.

Fixed correctly in 1.5
