Without Application plugin

The plugin also works without the application plugin. It adds the main class to the manifest file and brings it own configurable DSL extension. But there will be no run task without the Application plugin.

plugins {
    java
    id("de.infolektuell.jpackage")
}

jpackage {
  metadata.name = "Sample"
  launcher {
    mainModule = "example.app"
    mainClass = "org.example.App"
  }
}
