<p>I've got a workspace with multiple RCP plugin projects.</p>

<p>We've set the target platform, so we can build against a standard set of plugins, but are not able to see source code and Javadoc for all the platform plugins.</p>

<p>The Windows -> Preferences -> Plug-in Development -> Target Platform -> Source Code Locations page doesn't seem to have any effect when I add the eclipse directory (it only allows you to add directories). </p>

<p>Copying the source jars from the eclipse directory into the target platform has a similar effect.</p>

<p>What am I doing wrong? How do I attach a set of Source jars to my target platform?</p>

I can modify the target platform at runtime, using the
```
-install
```
runtime option. Keep the targetPlatform as the eclipse platform.
However, this loses a lot of the benefits of using a target platform in the first place - i.e. compile time safety.
