Error on execution from generate jar with gdx-backend-lwjgl3 and gdx-tools dependencies

[DanielChesters]

Issue details

When I generate a jar from a gdx projet with gdx-backend-lwjgl3 and gdx-tools dependencies and I try to run this jar, I have a error. The gdx application run perfectly with same configuration when I use Gradle to run this.

Reproduction steps/code

1. Create a new gdx project with setup app for desktop only
2. Migrate to gdx-backend-lwjgl3
3. Add gdx-tools dependency in desktop module
4. Do a ./gradlew clean dist
5. Do a java -jar desktop/build/libs/desktop-1.0.jar

Version of LibGDX and/or relevant dependencies

1.9.6 with gdx-backend-lwjgl3 and gdx-tools dependencies

You can't include gdx-tools with lwjgl3 backend on dist, these are not compatible. see #3726

[mgsx-dev]

Indeed, gdx-tools project have both core, editor and test code. Editor and test code are based on Lwjgl backend. If you only need some Lwjgl agnostic classes (for instance texture packer), you can exclude Lwjgl from gdx-tools dependency in your gradle build, something like that (not tested) :

compile "com.badlogicgames.gdx:gdx-tools:$gdxVersion" {
  exclude "com.badlogicgames.gdx:gdx-backend-lwjgl"
}

see https://docs.gradle.org/3.3/userguide/dependency_management.html#sub:exclude_transitive_dependencies

This is just a workaround, IMO gdx-tools should be split in some way.

Hope it's help.

This comment was a godsend. For those finding this, the syntax is a little off. Try adding the following to your :desktop dependencies in the root-level build.gradle file:

compile ("com.badlogicgames.gdx:gdx-tools:$gdxVersion") {
    exclude group: 'com.badlogicgames.gdx', module: 'gdx-backend-lwjgl'
}

I added it the following way, but still get the same error after gradlew clean dist and executing the jar.

project(":desktop") {
    apply plugin: "java-library"


    dependencies {
        implementation project(":core")
        api "com.badlogicgames.gdx:gdx-backend-lwjgl3:$gdxVersion"
        api "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-desktop"
        api "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-desktop"
        api "com.badlogicgames.gdx:gdx-bullet-platform:$gdxVersion:natives-desktop"
        api "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-desktop"
        api "com.badlogicgames.gdx:gdx-tools:$gdxVersion"
        api "com.badlogicgames.gdx-controllers:gdx-controllers-desktop:$gdxControllersVersion"
        compile ("com.badlogicgames.gdx:gdx-tools:$gdxVersion") {
            exclude group: 'com.badlogicgames.gdx', module: 'gdx-backend-lwjgl'
        }
    }

}```

@Amityville-DE There, you still depend on gdx-tools without the exclusion. You need to use:

project(":desktop") {
    apply plugin: "java-library"

    dependencies {
        implementation project(":core")
        api "com.badlogicgames.gdx:gdx-backend-lwjgl3:$gdxVersion"
        api "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-desktop"
        api "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-desktop"
        api "com.badlogicgames.gdx:gdx-bullet-platform:$gdxVersion:natives-desktop"
        api "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-desktop"
        // there was a problem line here.
        api "com.badlogicgames.gdx-controllers:gdx-controllers-desktop:$gdxControllersVersion"
        api ("com.badlogicgames.gdx:gdx-tools:$gdxVersion") {
            exclude group: 'com.badlogicgames.gdx', module: 'gdx-backend-lwjgl'
        }
    }
}

Note that excluding LWJGL means not all of gdx-tools will be runnable. It can only use the parts of libGDX that don't rely on any platform implementation, and because parts of gdx-tools use AWT or Swing, those must be used on a desktop JVM (not a headless one). I don't think gdx-tools was ever intended for use at runtime, because it isn't built to run on Android or other non-desktop platforms. It of course can still be used at runtime, just limited to desktop JVMs and such.
