I’m seeing the following error after upgrading the project to JDK 11. I have updated the CN1 Libraries from Extension Manager already and codename settings (codename1.arg.java.version=11) file with JDK. Please advise how did you resolve the following error –
*Property codename1.arg.java.version has a conflict.

You can’t change java.version to 11. It has to remain on 8 even if you’re using JDK 11. It indicates the language level supported by the compiler and is fixed at 8.
Edit codenameone_settings.properties and change the entry:
codename1.arg.java.version=11
Back to:
codename1.arg.java.version=8
