Supposing my maven project is located in /some/location/project and my current location is /another/location/ how can I run maven build without changing to project location cd /some/location/project?
You can use the parameter -f (or --file) and specify the path to your pom file, e.g. mvn -f /path/to/pom.xml
This runs maven "as if" it were in /path/to for the working directory.
