My gradle build fails for no reason

[DRD2k8]

Description

Whenever I build my fabric mod, the gradle build fails after 20 to 30 seconds and says "(Mod Directory)\build\loom-cache\remapped_working\loom_mappings_1_20_1_layered_hash_2198_v2.net.fabricmc.fabric-api-fabric-api-0.92.2+1.20.1.jar The process cannot access the file because it is being used by another process"! This even happens on architectury! Why does this happen!?

Maybe you have a Game Instance running or another Gradle process. Could also be an AV.

This happened to me the other day, what I did was:

Make sure only the IDE (or terminal) is open, and if it still fails, goto task manager for windows and select all entries with "JDK platform binary" and end all those tasks.

Also, is your OS mac, linux, or windows?
