Moving to UI for comment
Exception is happening in org.eclipse.xtext.ui.
@Jan Xtext 2.21 needs asm 7.2 which you dont have installed. you might find it here: https://download.eclipse.org/tools/orbit/downloads/drops/R20200224183213/repository/ maybe you should also use a newer Xtext version (2.25)
@Christian Thanks, I had ASM 5.2, 8 and 9.1, but not 7.2. I updated XText to 2.25 and now the error is gone. I wonder why the dependency hasn't been installed correctly... I hadn't installed XText intentionally, it must have been pre-installed with the eclipse version or as dependency to something. It also didn't offered an update, if I use "Check for updates". I had to manually install 2.25 via Marketplace. Thanks Jan-Patrick
@szarnekow is here anything we can do?
