Re: [lyo-dev] Lyo Generator Problem 
Hi

I've been using Lyo with Oxygen with no problems. Not sure about its status with Photon. 

Could you work out the versions of 2 sets of Plugins for me? (1) Sirius (2) Acceleo. Please see attached for what I am looking for.

"Wrong" versions of these plugins have caused problems before for me.

regards

I'm not sure, what the last version of eclipse was that code generation was working on. I'm on Photon, I switched a while ago from Oxygen.
Honestly I'm not sure if I tested Lyo with that...

I'm starting eclipse with JRE 1.8, my default JRE is a JDK 11.

I installed it from the stable update site.
