gdx-backend-lwjgl3 references natives that cannot be found or do not exist, causes build to fail

Issue details

In a new project created with the provided tool and imported with IntelliJ IDEA, with a project SDK of 18 and running on Linux, trying to run or build the project fails as gradle cannot locate “natives-linux-arm64” for lwjgl-glfw, lwjgl-openal, lwjgl-opengl, lwjgl-stb and lwjgl.

Version of libGDX and/or relevant dependencies

        gdxVersion = '1.11.0'
        roboVMVersion = '2.3.16'
        box2DLightsVersion = '1.5'
        ashleyVersion = '1.7.4'
        aiVersion = '1.8.2'
        gdxControllersVersion = '2.2.1'

With “fix”: Runs fine, however:

[ALSOFT] (EE) Failed to set real-time priority for thread: Operation not permitted (1)
[ALSOFT] (EE) Failed to set real-time priority for thread: Operation not permitted (1)

Please select the affected platforms

• Android
• iOS
• HTML/GWT
• Windows
• Linux
• macOS

The “fix”: This is not at all ideal, and essentially just excludes lwjgl, lwjgl-glfw etc. from gdx-backend-lwjgl3 and replaces it with all the same stuff except excluding the natives that cause trouble. I’ve commented out the windows and mac natives, because for some reason they cannot be found on my Linux machine similarly to the Linux ARM64 natives that originally caused this problem (which are also commented out). This is a problem because it will produce a binary that’s not actually cross-platform, however it at least runs and I can continue development. The list of natives is based on the pom.xml file for gdx-backend-lwjgl3.

Compare to this version given by the project creation tool, which “causes” the error described:

    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"
    }

This happens to me a lot; I usually just remove mavenLocal() from my Gradle repositories and it works as soon as I sync again. Gradle is not the most reliable software…

Oh, @WasabiThumb have you used pure maven with this same version? Like a project managed by maven bringing in deps of 3.3.1?

If you did, and had

<dependency>
  <groupId>org.lwjgl</groupId>
  <artifactId>lwjgl</artifactId>
  <version>3.3.1</version>
  <classifier>natives-linux</classifier>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>org.lwjgl</groupId>
  <artifactId>lwjgl</artifactId>
  <version>3.3.1</version>
  <classifier>natives-linux-arm32</classifier>
  <scope>compile</scope>
</dependency>
<dependency>
  <groupId>org.lwjgl</groupId>
  <artifactId>lwjgl</artifactId>
  <version>3.3.1</version>
  <classifier>natives-linux-arm64</classifier>
  <scope>compile</scope>
</dependency>

only, then it all makes sense.
