title: JavaScript validator throws NullPointerException in Eclipse
body: <p>I'm coding some PHP files on Eclipse IDE, and I keep getting an error that says "Building Workspace has encountered a problem" -- Workspace is the name of my project area.</p>
  
  <p>When I click on the "details" link I get this</p>
  
  <pre><code>Errors occurred during the build.
  Errors running builder 'JavaScript Validator' on project 'Ullman'.
  java.lang.NullPointerException
  </code></pre>
  
  <p>As mentioned, I'm working in PHP so I don't know why it's trying to set up JavaScript Validator. I can't figure out how to stop it from doing these things.  Anyone know?</p>
  
  <p>I'm not experienced, so please provide a detailed answer if you can.</p>
