Not sure if this question is for stackoverflow or superuser

EDIT: superuser doesn't even have a gradle tag, so I'm guessing this is for stackoverflow

Hi i am trying to run ./mach gradle app:test to test bug fixes in mozillas code

When I run it I get this error

Timeout waiting to lock artifact cache (/home/user/.gradle/caches/modules-2). It is currently in use by another Gradle instance.

I get the same error when running ./mach gradle app:checkstyle so I assume I would get this with and gradle command

I've checked to see what daemons where running with service --status-all but there i nothing there with the word gradle in it

The other questions I've looked at had answers that say to run gradle --stop to check if daemons are running. When I run that command it says Stopping daemon(s) and hangs

How can I fix this? I have tried closing and re-opening the terminal.
