It looks like some parts of the CLI GUI are loading.

Can make a few tweaks so the classes/code isn't loaded/reached if running from command line.

What happens if you run java -jar morphe-cli-1.6.2-all.jar -h?

[ddCeka]

What happens if you run java -jar morphe-cli-1.6.2-all.jar -h?

With param -h worked, without param -h show error like the report.

Which version of Java are you using?

[ddCeka]

Mine was this version used.

openjdk 21.0.10 2026-01-20
OpenJDK Runtime Environment (build 21.0.10)
OpenJDK 64-Bit Server VM (build 21.0.10, mixed mode)

Ah I just realised the reporter used eclipse one.

[l205306]

openjdk version "17.0.18" 2026-01-20 LTS
OpenJDK Runtime Environment Zulu17.64+17-CA (build 17.0.18+8-LTS)
OpenJDK 64-Bit Server VM Zulu17.64+17-CA (build 17.0.18+8-LTS, mixed mode, sharing)

JDK 17 should be no issue.

Yea the issue is headless environment. Right now, passing no args tries to load gui but since there is no display attached, it throws the error trying to load the gui.

@jamieclaw @ddCeka Could you guys check using the dev-3 release? It should be fixed now.

[jamieclaw]

@prateek-who it works, thanks!

@kitadai31 actually -h works on existing release version (1.6.2) and I have successfully migrated my CI pipeline to morphe. I suspect this issue only rise without any args supplied.

[ddCeka]

@prateek-who Can confirm, it works now
