linux - What is the correct way to use node dependent paths in Netbeans?

Question

I'm using Netbeans 7.1.2 on Linux (bash) with Maven2.

Depending on what computer on the network I log in to, the path to maven varies. It is either /gfs/blah/maven or /nfs/blah/maven. I have an environment variable to take care of this on the command line.

However, I am apparently not allowed to use an environment variable under Tools -> Options -> Miscellaneous -> Maven -> Maven Home

What is the correct was of handling this?

Thanks!
