title: Using maven outside of Eclipse
body: <p>I am already using maven outside of eclipse, but would like to use Eclipse as my main editor.  I don't want to use the maven already embedded with M2E.  I want to use mine located at /usr/bin/mvn.</p>
  
  <p>Under Window > Preferences, I try to add a maven installation at /usr/bin/mvn (clicking Ok does nothing; stays at the same window) and at /usr/bin (gives the error: <code>The selected directory is not a valid Maven directory.</code>.</p>
