Hi,
the UIMA Ruta Workbench has problems with newer Eclipse (> 4.8?) and Java (11) versions for some time now. We will fix the problem in the upcoming releases (which will require to increase the min required version of Eclipse). There are several workarounds for this problem concerning the current UIMA Ruta Workbench versions. I created a short description for some Ruta users and I wanted to share this: https://docs.google.com/document/d/11GnvmJfmHD-QsmCCS4F2-ueQAhIaDZPINz565kMMi-g Best Peter -- Dr. Peter Klügl Head of Text Mining/Machine Learning Averbis GmbH Salzstr. 15 79098 Freiburg Germany Fon: +49 761 708 394 0 Fax: +49 761 708 394 10 Email: peter.klu...@averbis.com Web: https://averbis.com Headquarters: Freiburg im Breisgau Register Court: Amtsgericht Freiburg im Breisgau, HRB 701080 Managing Directors: Dr. med.
