<p>I'm working on a eclipse plug-in and I've tried to create another test project seperate from the plug-in. The reason I do this is to not let the plug-in depend on jUnit when it is exported. However, I can't access the Eclipse Plug-in API when I do the testing. Whenever I try to add Plug-in dependencies the import list to that is empty.</p>

<p>Does anyone know how to import Eclipse plug-in API to an existing project? The workspace layout looks like this at the moment:</p>

<pre><code>+- com.foo.myplugin
|     |
|     +- JRE System Library
|     |
|     +- Plug-in Dependencies
|     |
|     +- src
|     |
|     +- icons, META-INF, plugin.xml, etc...
|
+- com.foo.myplugin.test
      |
      +- JRE System Library
      |
      +- JUnit 4
      |
      +- src
</code></pre>

You could try to add the plugin nature to your new myplugin.test project.
In your .project file:
```
```
<natures>

        <nature>org.eclipse.pde.PluginNature</nature>
        [...]
</natures>
```
```
Then in the .classpath, add:
```
```
<classpath>
        [...]
        <classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins"/>
        [...]
</classpath>
```
```
Delete your myplugin.test from the workspace, re-import that project and see if that does the trick...
