Re: [lyo-dev] Lyo Generator Problem
|
Hi Jan-Patrick,
What version of Eclipse were you using before. You are using Photon now, right?
Did you setup your environment, as instructed here? In particular, I am thinking of setting up the Java JDK in Eclipse
https://wiki.eclipse.org/Lyo/General_Setup_for_OSLC4J_Development
Finally, did you download Lyo Designer from the stable site update-site http://download.eclipse.org/lyo/p2/stable/? Or http://download.eclipse.org/lyo/p2/edge/?
regards

Hi,
I just had to re-install/setup my eclipse, but now my toolchain isn't generating any more. There's no error message in eclipse, but I was able to find the following in the log file:
!ENTRY org.eclipse.ui 4 0 2019-04-15 11:33:14.273 !MESSAGE Unhandled event loop exception !STACK 0

I've attached my eclipse configuration as printed out via Help - About Eclipse...
How can I fix this?
Best regards
