#21532 Possible cache race on jvm dependency artifacts via bsp Issue created by jgranstrom Describe the bug Projects with multiple bsp groups seem to hit a cache race when materializing jars across the groups. I have a repro here and opening it in intellij will if not immediately after a few re-requests from bsp start failing due to read-only files hit in the target directory for bsp jars. Seen in BSP logs from intellij:

Engine traceback:
  in root
    ..
  in pants.backend.scala.bsp.rules.bsp_scalac_options_request
    ..

...

native_engine.IntrinsicError: Error copying bytes from /Users/johngranstrom/.cache/pants/lmdb_store/immutable/files/e8/e805c5ccc0241ceab8d55795633f909eafe1826bdf32214fc2869ffaee61f086

Flags on the target bsp jars are all over:
