When I go to the Extensions tab in the plug-in editor it has the text "8 warnings detected" next to the heading "Extensions" yet it doesn't display any "!" next to any of the extensions and the plugin.xml contains no warnings. Also, when I right click on an extension point to create a new extension the only option for the "New" menu is "Generic".

What's wrong? How do I find the problem(s) and get the extension editor working again?

Looks like you don't have the schema of the extension point in your
installation.

OK, how do I fix that? I haven't changed anything in the installation as far as I know and it was working before.

I had faced similar situation some time back and I did notice
that if I updated my eclipse from the update site and restarted things started working well.

Though I am not sure if this s the best approach but till nothing else one can try.

You don't have the source packages installed and the exsd-Files are only
part of the source distro.

Thanks Tom, adding in the source packages solved the problem. I have no idea why they decided to disappear all by themselves!

This problem has resurfaced and this time I can't remember exactly what I did last time to resolve it. I know I have to "install the source packages" so I have re-downloaded the RCP SDK from the update center and then added the org.eclipse.platform.source (3.6.2) plug-in as a dependency for my plug-in but I still have the same problem. I have warnings and the only extension I can add is "Generic".

What am I missing?

Thanks,

OK I have managed to fix it again but it wasn't pretty. For some reason the IDE could not read the manifests of the source plug-ins and they were shown with red X's in the Target Platform section of the Plug-in Development Preferences page when I chose Edit on the active platform. I basically had to reinstall Eclipse to fix this problem because I needed to move on. The initial problem was definitely related to me not having the source packages installed (they are available from the update site for The Eclipse Project Updates) but this time it seems they became corrupted for some reason and could not be used by the IDE. I am sure there was a neater way to solve this problem but I didn't have time to explore it.
