workflow.dsl fails to build

[metadatadriven]

My build is failing at org.eclipse.emfcloud.coffee.workflow.dsl which looks like its caused by a a problem in org.eclipse.equinox which is a dependency of xtext. To reproduce, run.sh:

After some digging, I think the root cause might be a dependency in xtext? See issue:

eclipse-xtext/xtext#2077

Unfortunately my maven foo is not good enough to fix or workaround. Any ideas?

Hi @metadatadriven ,
sorry for the late reply. The error looks strange. Did you simply run run.sh or run.sh -b ?
I assume you are also building the master branch?

[metadatadriven]

It was happening when the backend was building the workflow.dsl extension - the problem was caused by xtext.. this has now been fixed and backend is building ok!.. I'm having problems building the frontend now but that is a different issue:)
eclipse-xtext/xtext#2077

Thank you for the update!
