Application "org.eclipse.ui.ide.workbench" could not be found in the registry

Question

I am trying to build an RCP Application as done here.

Sadly i am gettin an error message that doesn't makes much sense to me. Maybe one of you has an idea.

Answer 1

Ok, it's done.I had to add the 'org.eclipse.core.runtime.applications' to my Extensions.

Answer 2

Another approach that worked for me when developing an Eclipse plugin (not a standalone RCP application) and getting the "java.lang.RuntimeException: Application "org.eclipse.ui.ide.workbench" could not be found in the registry." exception (I found this SO thread when googling this error, and also found the following):
https://www.eclipse.org/forums/index.php?t=msg&th=155457&goto=820447&#msg_820447

You have to go to "Run Configurations...", and on the "Plug-ins" tab, you also have to MANUALLY check org.eclipse.ui.ide.application plug-in. That's all (or maybe you'll also need org.eclipse.core.net, I didn't need it).

Previously I clicked "Add Required Plug-ins", "Validate Plug-ins", but none of them marked this plug-in as needed, so I got this exception all the time I wanted to start a new Eclipse instance. By adding it manually, the problem got away.

Answer 3

For the error message

java.lang.RuntimeException: Application "org.eclipse.ui.ide.workbench" could not be found in the registry.

the easiest solution I found is to add the plugin called 'org.eclipse.equinox.simpleconfigurator'. This works especially for the latest eclipse versions (in my case Neon.3 v4.*).

Answer 4

The easiest way to solve that problem in Eclipse is:

-> Go to "Run" and select "Run Configurations"
-> Go to "Plug-ins"-Tab and hit the "Add Required Plug-ins"-Button
-> Than Apply!

Eclipse will automatically select all the plugins needed.
