Hey Sam,
Since you’re running in a container it may be easier to just pass this as an enviroment variable. Depending on your method (docker run or docker compose) you could achieve this with the following:
Docker run:
-e INSTALL4J_ADD_VM_PARAMS="-Dnexus.datastore.enabled"
Docker compose:
environment:
- INSTALL4J_ADD_VM_PARAMS=-Dnexus.datastore.enabled
Hope this helps
