      with:
        # If your pom.xml <maven.compiler.source> version is not in 1.8.x,
        # change the Java version to match the version in pom.xml <maven.compiler.source>
        java-version: '1.8.x'

JavaScript

env:
  NODE_VERSION: '14.x'                # set this to the node version to use
