How do you clear Apache Maven's cache?

maven caching

Recently, Apache Maven seems to be having caching issues. Performing clean installs on our projects using Windows Vista or Windows 7 sometimes produce artifacts with the same data as a previous build even though the newer artifact's files should have been updated.

Is there any way to clear this cache to force maven to always trigger a clean build of the local artifact that should be built?

In particular, we're having issues building a webapp with the war plugin. Maven version is 3.0.3. War plugin version is 2.1.1.

Delete the artifacts (or the full local repo) from c:\Users\<username>\.m2\repository by hand.
