Hello all,

I want to migrate an existing application(3.7) to an e4 RCP application.

But i have a few problems with this task. I have used Lars Vogel's article about the Compatibility Layer to get the e4 App running. But there are problems with the plug-ins I added to the Product file (They are missing for me).

So biggest problem are the repositories i use, they seem to have missing artifacts and features.

download.eclipse.org/e4/updates/0.12-I-builds
download.eclipse.org/eclipse/updates/3.8milestones
download.eclipse.org/eclipse/updates/4.2-I-builds

But in this repositories there are missing Features for me:
org.eclipse.emf.feature.group
org.eclipse.gef.feature.group

and also there are missing plug-ins in the product which are essential for e4 imho.
One of them is the org.eclipse.e4.ui.workbench.addons.swt plugin.

So are there more repository for e4 or must i work with the downloadable p2 repository from Version 4.2? Or is this a Cache problem vom eclipse?

Another question is it possible to build the e4 RCP App with maven-tycho, cause i use it for the 3.7 application.
Thanks for your help
Marvin

Thanks for the help Lars,
this helped me for the GEF and EMF Features.

I solved another problem with adding
org.eclipse.core.runtime
org.eclipse.equinox.ds
org.eclipse.equinox.event
to the autostart of my Launch configuration. After i have done this, i could build with Maven Tycho. So i got a launchable e4 RCP app.

So my app runs now as an RCP e4 application. But not in eclipse, there i get this error stack.

Thanks for Help
Marvin
