title: maven, APT problems, eclipse
body: <p>I have a maven project that I am trying to build in my <code>workspace</code> in <code>eclipse</code>. Now, I changed my <code>java</code> path from <code>'C:\Program Files\Java\jdk1.7.0_79'</code> to <code>'C:\new\Java\jdk1.7.0_79'</code> for some valid reasons.</p>
  
  <p>I updated the path in <code>environment variable</code> and <code>eclipse</code> accordingly. However, when I build the project, I face the following error:</p>
  
  <blockquote>
    <p>Project UPF-Desktop is missing required annotation processor
    library:'C:\Program Files\Java\jdk1.7.0_79\lib\tools.jar'      Annotation
    processor factory path     APT Build Problem</p>
  </blockquote>
  
  <p><code>tools.jar</code> is present in the new <code>Java</code> location, but it is looking for <code>tools.jar</code> in a non-existing location, altogether.</p>
