I was trying to upgrade my project from 2.10 to 2.12. I encountered follow error while build with maven. I thought there may be somewhere not compatible with 2.10. So I installed the latest eclipse oxygen with xtext and create an empty project with wizard. But when I build it with maven I still got the same error. Can someone help me?

I was tring to build the "xcore-maven-example" project, and I got the same error.

[ERROR] Failed to execute goal org.eclipse.xtext:xtext-maven-plugin:2.11.0:generate (default) on project xcore-maven-example:

Building with "mvn clean compile -U" was a good solution for me.
I do not understand why it helps, but it works.
