Eclipse showing a warning when Bundle-Classpath has a system property
<p>I have an external library set at my Bundle-ClassPath which will be located at different paths in Windows and Linux.
So I've declared the Bundle-ClassPath using a system property as follows:</p>

<pre><code>Bundle-ClassPath: .,
 external:$path_to_my_lib$
</code></pre>

<p>It's all compiling and running as it should. But Eclipse is showing a warning.</p>

<blockquote>
  <p>'source.external:$path_to_my_lib$' build entry is missing</p>
</blockquote>

<p>What should I do to solve it?</p>
