Since my Dropwizard project isn't entirely working at the moment, I decided to try out a different library: libgdx.
This code runes my project flawlessly in Java:
public class DesktopStarter {
public static void main(String[] args) {
LwjglApplicationConfiguration cfg = new LwjglApplicationConfiguration();
cfg.title = "Title";
cfg.useGL20 = true;
cfg.width = 800;
cfg.height = 480;
new LwjglApplication(new MyLibgdxGame(), cfg);
}
}
The corresponding Kotlin code:
fun main(args: Array<String>) {
val cfg = LwjglApplicationConfiguration()
cfg.title = "Title"
cfg.useGL20 = true
cfg.width = 800
cfg.height = 480
LwjglApplication(MyLibgdxGame(), cfg)
}
Does not. It fails with this huge exception:
Kotlin: [Internal Error] org.jetbrains.jet.codegen.CompilationException: Back-end (JVM) Internal error: Error types are not allowed when classBuilderMode = FULL. For declaration null:null in null:null
Cause: Error types are not allowed when classBuilderMode = FULL. For declaration null:null in null:null

Sadly, my brief google searches haven’t come up with anything recent or entirely relevant pertaining to this problem. I would be grateful for any help in resolving this issue.
