title: General error during semantic analysis: Unsupported class file major version 57
body: <p>I'm trying to setup libgdx for a desktop game and when I try to generate the project I have this error and the build fails.
  I've the latest versions of Java(13.0.2) and Gradle(6.6), both set as environment variables in the path. Can somebody help me?</p>
  <p>The error looks like this:</p>
  <pre><code>Could not compile settings file 'C:\Users\noemi\Desktop\Test\settings.gradle'.
  &gt; startup failed:
    General error during semantic analysis: Unsupported class file major version 57
    
    java.lang.IllegalArgumentException: Unsupported class file major version 57 
  </code></pre>
