ERROR: Unsupported class file major version 65

[EliasHeydrich]

Hi there 😉

I also have the issue reported here previously:
Execution default of goal com.github.akman:jpackage-maven-plugin:0.1.5:jpackage failed: Unsupported class file major version 65

Using a Java 21 LTSthere, in the Adoptium variant, on a Win10 64 bit. Also, JLinker ran fine.

If there is indeed a version 0.1.6 of this plugin that fixes the problem, as stated in that other ticket, could that be publically released (as I am not moving to Rust)?

Got the same problem.
Working in Java 17 Adoptium with target version 17.
Not working with Java 21 Adoptium and target version 17

I can confirm this. I get the same Error when I try to upgrade from Java 17 to Java 21 LTS:

With Java 17 JLink (through javafx-maven-plugin) and JPackage (through this plugin) worked fine, now it failes on the JPackage Plugin Step.

My Java version and tool chain relevant pom properties are in this case:

    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

i work with this one : https://github.com/petr-panteleyev/jpackage-maven-plugin
i don't know if it's working actually with 21 tell me if you try and if it's working :)

[Ulathar]

Didn't try that one, yet, because it executes JLink on its own (if I read the documentation right). JLink is part of a different Build step on my side and I don't want another plugin to rerun it.

I can confirm that I just tested it with Java 21 and everything is OK.
As for JLINK, I can't tell you any more, but I get the impression that it allows you to launch JLINK if you need to, but that by default, it doesn't call it.

@Akman this project is it no longer being maintained?
Because I can see that everything is ready for 0.1.6, but nothing has been released.

[Ulathar]

Just gave it a quick shot: cloned the repo and build it locally (mvn install) as v0.1.6-SNAPSHOT.
After that using this local build of the plugin in my projects I am able to build with them with Java 21 again.

So yes, the current master branch seems to be working just fine, at least after a very quick test, but does not seem to have an (official) v0.1.6 release (yet?).

[cavoirom]

The code base is reliable and work with JDK 25 (I created a PR to upgrade the needed dependency version). I hope we could release 0.1.6.
