Subject [jira] [Commented] (UIMA-4803) Ruta update to 2.4 breaks project
Date Mon, 29 Feb 2016 10:01:18 GMT

    [ https://issues.apache.org/jira/browse/UIMA-4803?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15171674#comment-15171674

Peter Klügl commented on UIMA-4803:

Ok, let's narrow down the problem.

I assume that the problem only occurs when you launch a script, e.g., press the run/debug
button, right? Does the exception occur in the console of the launched script, or is there
a error dialog or problem report?

Do you start the Ruta Workbench from within an Eclipse workspace or is the Workbench installed
in the started Eclipse? If yes, is the option "do not use a new VM (or similar)" in the preferences
(UIMA Ruta/Project Management) activated?

> 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.
