Most importantly, resource loading now works correctly in tests and the application plugin.

Note that due to plugin portal changes, the installation instructions for the plugin are now slightly different (notice the classpath is no longer prefixed with gradle.plugin.

buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "org.javamodularity:moduleplugin:1.1.1"
  }
}
