# sbt/sbt#9455: an environmental I/O compile failure must not be cached and replayed forever.
# Make the compile output dir read-only so compile fails with an "error writing" I/O error.
> denyClassDir
-> compile
# Heal the environment. The sources are unchanged, so without the fix the cached environmental
# failure is replayed and this compile fails; with the fix the compile actually runs and succeeds.
> allowClassDir
