Using the adopt install jdk action returns a warning

      - name: Set up AdoptOpenJDK 15
        uses: AdoptOpenJDK/install-jdk@v1
        with:
          version: '15'
          architecture: x64

this is the warning with some errors.

probably you know it but an issue is just a reminder :)
thank you for your great product.

Thanks for the report! This should already be fixed on master by e063617. I'll validate the fix tomorrow (13.10) and publish 1.1.1.

e063617 only partially fixed the issue as it only upgraded the dependency. I rebuilt the action in 8f7e2a2 and just released 1.1.1 with the fix. If you are using AdoptOpenJDK/install-jdk@v1, you should not see this deprecation warning anymore going forward!
