PDE development: How to find out where a plugin from my target platform originates from? <p>In my eclipse project I have set a target platform via target definition file.</p> <p>I've noticed that a specific plug-in is present in two different versions: 1.7.9 and 1.7.2. I checked this by doing "Window -> Show View -> Plug-in Development -> Target Platform State" and search for the plug-in name.</p> <p>Both versions appear and they are located in <code>.metadata\.plugins\org.eclipse.pde.core\.bundle_pool\plugins</code></p> <p>I want to get rid of 1.7.2, but when I open the target definition file it does only refer to the 1.7.9 version:</p> <pre><code>&lt;unit id="slf4j.api" version="1.7.9"/&gt; </code></pre> <p>How can I find out where the plug-in originates from, in order to get rid of it?</p>
