Vitruv MWE2 Exceptions

[MartinLoeper]

I installed the whole KAMP-DSL bundle via KAMP-DSL-Installer on the Surface PRO.
The installation did not finish successfully. The MWE2 Builds in Vitruv do not complete as expected.
We must look into this.
I noticed a lot of changes in the Vitruv project during the last 2 weeks. Maybe something was changed.
I will let them know as soon as I find out what is going wrong.
In the meantime everyone who uses the installer must manually check out an old version of Vitruv. e.g. b8ac5bf592aa2ec6d3369ceba1b7dfab21aba4ff

We should also think about checking out Vitruv partially.
The whole projects looks a bit instable to me.

I found two closed issues indicating there might be migration issues from Neon to Oxygen:

vitruv-tools/Vitruv#87
vitruv-tools/Vitruv#88

I talked to Joshua from the Vitruv team and he explained that we need to run the Maven Tycho tasks in order to make the MWE 2 workflow work again.

I leave this issue open until I update the README.md...

Moreover Joshua suggested to remove the Vitruvius dependency because it is causing too much overhead and it is very likely they remove the metamodel import feature in the future.

This one is superseded by #88
