Mule - [WARNING] MULE_HOME is not set - displayed when building with Maven

Question

I'm trying to deploy a Mule application to Standalone using Maven, but Maven is unable to move my app to the relevant apps folder and I'm given the following warning:

[WARNING] MULE_HOME is not set, not copying <app-name>

However, MULE_HOME is set, and a simple echo $MULE_HOME in Terminal gives the following, which is correct:

/opt/mule

Is there a known fix to this? Currently having to manually copy to the apps directory.

Ok, I've figured out where the issue was here. My standalone instance of Mule is in a directory /opt/mule-standalone-3.4.0 with an alias /opt/mule pointing to the same location. For some reason, Maven didn't like MULE_HOME being set to the alias. When amended to point to the actual directory, all worked fine.
