@matrei do you have any idea why GH_TOKEN is not resolving?

      - name: "🔨 Run Build"
        id: build
        env:
          GITHUB_ACTOR: ${{ secrets.GITHUB_ACTOR }}
          GH_TOKEN: ${{ secrets.GH_TOKEN }}
          DEVELOCITY_ACCESS_KEY: ${{ secrets.GRADLE_ENTERPRISE_ACCESS_KEY }}
          DEVELOCITY_BUILD_CACHE_NODE_USER: ${{ secrets.GRADLE_ENTERPRISE_BUILD_CACHE_NODE_USER }}
          DEVELOCITY_BUILD_CACHE_NODE_KEY: ${{ secrets.GRADLE_ENTERPRISE_BUILD_CACHE_NODE_KEY }}
        run: ./gradlew build --refresh-dependencies

        println "Check 1:${System.getenv('GITHUB_ACTOR')?.size()} 2:${System.getenv('GH_TOKEN')?.size()} 3:${prj.name == 'grails-plugin-gsp'?:'skip'} 4:${!sitemeshVersion.endsWith('-SNAPSHOT')}
