  <p>I wanted to run a mvn command in free style project. I specified the Maven tool and its home under "Tool Locations" and that didn't help. The job failed for not being able to find mvn. I followed this <a href="https://stackoverflow.com/a/25533545/251096">solution</a> and modified the PATH variable to include maven path. That did the trick. </p>
  
  <p>So how exactly does specifying Tool Locations help? Is it just to help users see the tool paths when they visit Jenkins node configuration site?</p>
