+1. I have done this. Caching cannot be disabled: it is what maven does. But you can control where the cache is stored. The final step is to invoke maven with:

mvn -s /path/to/alternate/settings.xml

With this command-line option and settings defined as noted by Stephen below, nothing will be written to the user home directory.

Kind regards,
Ben.

In the users or global settings this default can be changed to some other
location. (See<localRepository>  in
http://maven.apache.org/settings.html#Simple_Values)

Keep in mind that the cache is not concurrent safe, and is definitely not
designed to be shared by multiple users as it can and does get used to
store a user's temporary build artifacts if they do "mvn install"

Our recommendation is that each user has their own cache, and if there is a
strong likelyhood of a user running multiple concurrent builds of the same
or similar sets of artifacts then those builds should be using their own
cache... e.g. a CI server should have a separate cache for each build job.

 complaining about maven writing to home directory during compile.

Is there any command line argument to prevent this (to turn off caching).
