I've tried the latest patch set from this Gerrit change, and it looks like I get into the same problem, i.e. the first launch does not seem to run (at least not producing any logging output):
But I do bump into another issue. During the launch of GenerateTumlrt.mwe2 the following is logged:
2606 [main] ERROR mf.mwe2.launch.runtime.Mwe2Launcher - Problems instantiating module

Maybe this is just a consequence of the first launch that has been run. But when trying to run the setup tasks manually again, using Help > Perform Setup Tasks..., the same error occurs for me again. First I had to do a Project > Clean... and the run the setup tasks once again to get it all to work.
I tried performing the setup from scratch twice (removing my repo, the installation and the workspace), and one additional thing that I could see was that the order between the different tasks was different. One thing was the first time I tried, the targlets task was performed *after* the build tasks. And I assume that if the targlets task has not been done, then the building can fail since the target platform has not been updated yet. The second time around though, the targlets task was performed before the building tasks. Not sure it this has any impact, and why the order changed (it could have been that I selected the subprojects to import in the Eclipse Installer, in a different order, which I guess could impact the order of tasks being performed during setup).
Not sure if this helps or not.
