title: Eclipse: How to move the .externalToolBuilders directory?
body: <p>I have built a small External Tool Builders for 3 eclipse projects.
  How can I tell eclipse to use a (shared) directory outsite of the project directory?</p>
  
  <p>I figgerd out that eclipse stores that settings in the .project file. But it seems that it is not possible to change the value:</p>
  
  <pre><code>&lt;buildCommand&gt;
      &lt;name&gt;org.eclipse.ui.externaltools.ExternalToolBuilder&lt;/name&gt;
      &lt;arguments&gt;
          &lt;dictionary&gt;
              &lt;key&gt;LaunchConfigHandle&lt;/key&gt;
              &lt;value&gt;&amp;lt;project&amp;gt;/.externalToolBuilders/do cleanup.launch&lt;/value&gt;
          &lt;/dictionary&gt;
      &lt;/arguments&gt;
  &lt;/buildCommand&gt;
  </code></pre>
  
  <p>I tied the values:</p>
  
  <ul>
  <li><code>&amp;lt;project&amp;gt;/../MyUtils/ExternalToolBuilders/do cleanup.launch</code></li>
  <li><code>../MyUtils/ExternalToolBuilders/do cleanup.launch</code></li>
  <li><code>x:/full/path/to/file/do cleanup.launch</code></li>
  </ul>
