Kai, per your request

- deleted Eclipse folder on Mac OS X
- deleted ~/.p2
- deleted ~/.eclipse

did new install from installer, accepted all licenses etc (e.g. seems nothing in cache here that could upset the process).

- Clean project
- Perform startup tasks

Have the above message on all mwe2 plug-ins. Don't understand

K

It seems that the previous installation of the XText SDK has polluted my branch of the ESH repo. That in itself is quite strange, because even when copying back the .launch of the working official repo to my branch, I has this error. The solution was in installing from scratch and importing back all packages from my own repo.

Good that you have solved it!
Anyhow, for the future I have just built a new Oomph project that you might be interested in:
With the Eclipse Installer, you now have the option "Github.com->openHAB-->openHAB 2 with Eclipse SmartHome Core".
This will install you a workspace with openHAB 2 and the main bundles (meaning all but model and designer stuff) of ESH. With the new launch config https://github.com/openhab/openhab2/blob/master/targetplatform/openHAB_with_ESH.launch you can then directly run an openHAB 2 with the modifications you do to ESH code in your workspace.
I think that will make the development much easier - please have a try and let me know what you think!
