Compiling error (Missing JavaFX dependency)

[loeffelpan]

Hey,
got this on compiling 0.5.2.

I cannot reproduce this on Ubuntu with the latest commit.

Hmm, first time I tried to compile this directly on my RPi.
Java is OpenJDK8. Maybe that‘s the issue?

Compiling (like before) on my Ubuntu works (with OpenJDK10).

[devgianlu]

OpenJDK8 doesn't include JavaFx (adoptium/temurin-build#577), install JavaFX in your system or run mvn -pl '!api-client' package to skip the module that requires the dependency.

Thanks.
Does this mean, that api-client wouldn’t work anyway on this device?
Then I would run mvn -pl core,common package and build without api, api-client and interactive-cli. Would that work?

[devgianlu]

The api-client module will refuse to compile until you install JavaFX on the system.

Then I would run mvn -pl core,common package and build without api, api-client and interactive-cli. Would that work?

Should work totally fine.
