Maven "exec-maven-plugin" --> Could not load class: org.eclipse.core.runtime.OperationC [message #1689610]

Hi guys,

I am trying to migrate my project from Xtext 2.7.3 to 2.8.0 and I am getting the following error when I changed the xtext version

Could not load class: org.eclipse.core.runtime.OperationCanceledException

Also I tried to use xtext 2.8.1 and the xtend plugin with version 2.8.0 but that case I got the following error

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java (default) on project org.mule.tooling.dfl: Execution default of goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java failed: Plugin org.codehaus.mojo:exec-maven-plugin:1.2.1 or one of its dependencies could not be resolved: The following artifacts could not be resolved: org.eclipse.xtext:org.eclipse.xtext.xtext:jar:2.8.1, org.eclipse.xtext:org.eclipse.xtext.xbase:jar:2.8.1: Could not find artifact org.eclipse.xtext:org.eclipse.xtext.xtext:jar:2.8.1 in mule-ee-snapshots (http://repository-master.mulesoft.org/nexus/content/repositories/ci-snapshots/) -> [Help 1]

Do you know if there is any known issue with maven in xtext 2.8.0

P.S: I am running maven over tycho.

Regards,
Luis

I solved my issue using the dependency mentioned in this post

https://www.eclipse.org/forums/index.php/t/1046879/

However, I would like to know if someone can confirm if this is the way to go.

Thanks in advance

Yes, that's the way to go for 2.8.0.
In 2.8.1 we will add a transitive dependency from org.eclipse.xtext.xtext to org.eclipse.equinox.common.
2.8.1 maven artifacts will be released today.
