Tried to play with the Gitlab issues examples and got the following exception when running desktop application:

> Task desktoprun

Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedClassVersionError: org/jetbrains/skiko/Library has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

I use macOs with both jdk8 and jdk14 installed and jdk14 is active according to terminal:
$ java -version
openjdk version "14.0.2" 2020-07-14

I got a hunch somehow jdk8 is used for compiling but I don't know how to force jdk14

Thanks, will try it
Eventually I got it running by switching the project bytecode version from 8 to 14.

I’ve got similar issue with running from cli via gradle, it was working fine for me with IDEA, so thats I was searching for gradle related solution for the issue, this java build chain is totaly new…

Set Gradle JVM to 11 or later.

[Michal Harakal]

you probably mean -Dorg.gradle.java.home if I want to run gradle from terminal

[Michal Harakal]

also switching with sdkman (macos Big Sur) works well
