Grails App running in Docker Container not using Local Packages - docker

Question

I'm currently trying to run our app that's in Grails 2.3.11 through docker-compose with the database. I have the database up and running without issue, and also the app container sets up grails and starts the compilation process, but it goes on to downloading all the packages every time I stop and restart the package. This becomes an issue because we have to download so many packages (And there's a bunch of errors we have to work around because Grails 2). I've tried to mount my local grails folders into the container to have it run off of those but it seems to not be having any success. Is there something obvious I'm doing wrong, or some way I can easily check where the issue might be?
I'm also attempting to map all local database information into the mysql container with issue. But I haven't looked into it much yet, if you see an obvious issue there that would be helpful.

So the mapping I was using ended up not being correct. I was going off a file mapping from 1 article and ended up working after trying another working mapping. I made the switch below:
original:
volumes:
- ~/.m2:/home/developer/.m2
- ~/.gradle:/home/developer/.gradle
- ~/.grails:/home/developer/.grails
- ./:/app
new:
volumes:
- ~/.m2:/root/.m2
- ~/.gradle:/root/.gradle
- ~/.grails:/root/.grails
- ./:/app
