UIMA Ruta version 3.1.0

Question

I've upgraded the Uima Ruta version to 3.1.0 in Ruta Workbench. I tried with normal Ruta project its working fine but while convert into maven project i'm getting below error.

    Exception in thread "main" org.apache.uima.analysis_engine.AnalysisEngineProcessException: The JCAS cover class "org.apache.uima.ruta.type.TokenSeed_Type" could not be loaded.

Thanks in advance ScreenShot FYI:

I assume that there are two different versions of UIMA Ruta involved.

One version is the version of the Ruta Workbench as seen in the screenshot in the question.

When you run a Ruta script/analysis engine in maven context, then the classpath of the maven dependencies is the relevant one. This means that you are somewhat independent of the installed plugins if you develop a UIMA/Ruta based maven project.

In your case, I assume that there is an old ruta version in the maven dependencies. Or there are several and the old one wins.
