I would like to incorporate a ConsoleView into my Eclipse E4 RCP application.

When I try to use the JFace TextViewer, I get the following error: (And that's after I add it to the plugin dependancies)

!ENTRY com.jsh.ghostworker.ui 2 0 2016-02-01 13:06:33.267
!MESSAGE Could not resolve module: com.jsh.ghostworker.ui [90]

Any pointers would be welcome.

you have not updated your launch configuration after adding the
dependency to your project.

Thanks for your reply Tom.

That's exactly what the problem was. It had me beat for a few days and it was driving me mad!

For those with similar problems, I had to go to

Run->Run Configurations... ->select my run (or launch) configuration->Plugin tag

and then check the box for the jface.text plugin.

I'm wondering though if the tooling shouldn't sort this out. For example, if I add the event broker to my application, I just add it to to the Required Plugins section in the Pugin definition. I don't need to add it to the launch configuration. Similarly, if I use my own jars, I simply edit the Runtime section in the plugin. Again no need to edit the launch configuration.

It's very hard to do that appropriately and even if correct I would turn
this feature off immediately.

This is because everything needs the event broker hence the bundles are
already active in your launch config.
