What do I need to do to resolve bundle org.eclipse.rap.ui cannot be resolved in eclipse helios?

Question

Hi,

I don't know what I have done wrong but it seems pretty major yet I can't figure it out. I'm using Eclipse Helios to create a RCP / RAP application. I downloaded and installed the RCP / RAP IDE and I could previously launch RAP applications (although there were some runtime exceptions about something missing). Now when I create a new plug-in project using the rap hello world template I get 49 errors which I can resolve down to about 4 but the bundle org.eclipse.rap.ui cannot be resolved has got me.

It seems the RAP UI plugin is missing from your install.

First look at the plugins folder of your Helios install and check the presence of the org.eclipse.rap.ui plugin.

If not present, download again Helios RCP / RAP ide. It must be present otherwise there is a problem at eclipse.org but I am sure this is almost impossible ;-)

If present, open the plugin registry view Window -> Show View -> Other -> Plugin Dev -> Plugin registry and look for this missing plugin inside it.

If you see the plugin, right click on it and check Show Advanced Operations. Then right click again on it and select Diagnose. Here you should get information about the missing dependencies explaining why Eclipse can't find this plugin.

Hope this can help
