@Borealis404 Apparently, the latest version of this plugin is not compatible with Java 8 due to Jetty 11.

You need a version with Jetty 9 to run it on Java 8. The last version of this plugin with that version should be 2.3.0.

In case you're wondering, Jetty 9 Community support ends tomorrow, 2022-06-01.

Also, Java 8 Active support has ended 2022-03-31.

I'm surprised that nobody has raised this before.

Either way I'm leaning towards "ignoring" this. If you need JVM 8 support, use the old plugin version or upgrade your JVM.
