Peter Klügl commented on UIMA-4803:
-----------------------------------
The error message indicates the problem: the class with the main method is not
in the classpath. No idea why the message is in German (I always thought it is
in German on my machine because of some local java language setting).
Could you log the utilized classpath in RutaLaunchConfigurationDelegate (see my
comment from 03/Mar/16). And then maybe debug why the classes of ruta-ep-ide-ui
are not added to the classpath?

> URL: https://issues.apache.org/jira/browse/UIMA-4803
> Project: UIMA
> Issue Type: Bug
> Components: ruta
> Affects Versions: 2.4.0ruta
> Environment: Eclipse Luna, OSX
> Reporter: Matthias Grabmair
> Assignee: Peter Klügl
> Priority: Blocker
> Fix For: 2.4.1ruta

>
> Updating to Ruta 2.4 causes my project to no longer compile. The main script
> quits with the exception below. Occurs in both Eclipse Luna and Mars with
> UIMA 2.8.1. I did "UIMA Ruta" -> "Update Project" and "UIMA Ruta" -> "Convert
> to Ruta Project" but it did not help. Uninstalling 2.4 and reinstalling 2.3.1
> fixes it.
> This seems to be similar to https://issues.apache.org/jira/browse/UIMA-3189
