OperationCanceledException while running MWE2 Workflow [message #1667725]

Hello!

I am new to Xtext and I am trying to generate language artifacts as described in the 15 minutes tutorial [1] by "Run As → MWE2 Workflow".

I get the following exception:

Could not load class: org.eclipse.core.runtime.OperationCanceledException
Add org.eclipse.equinox.common to the class path.

The first time I tried to run the workflow there was a question about downloading some additional stuff for MWE2. I am sitting behind an proxy server and although I set up a proxy in my Eclipse preferences (and I am able to access the Eclipse marketplace for example) MWE2 was not able to download. So probably this caused the exception?

I am using the official pre-configured Eclipse version [2].

Does anybody know, how to solve this problem?

Best regards,
John
