title: How do you clear Apache Maven's cache?
body: <p>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.</p>
  
  <p>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?</p>
  
  <p>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.</p>
