Does app engine pipe 1.6.0 have support for Java 17 and/or 21?

[Bruce Wilcox]

If yes, what docker image is available?

I need a successor to 

maven:3.8.3-openjdk-11

Hi @Bruce Wilcox . According to gcloud app deploy Java17 and 21 versions are supported.

google-app-engine-deploy pipe based on google/cloud-sdk:473.0.0, where:

There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-11-openjdk-amd64/bin/java

My question has to do with what docker image will work.

```

image: maven:3.8.3-openjdk-11
pipelines:
  branches:
    master:
      - step:
          caches:
            - maven
          image: maven:3.8.3-openjdk-11
          name: Build, stage, and deploy App Engine content
          deployment: production
          script:
            - python3 --version
            - mvn --define skipTests=true --activate-profiles useItips --settings settings.xml install appengine:stage
            - ls -la target/appengine-staging/app.yaml
            - cat target/appengine-staging/app.yaml
            - pipe: atlassian/google-app-engine-deploy:1.6.0
              variables:
                KEY_FILE: ${XXXX_SERVICE_ACCOUNT_KEY}
                PROJECT: 'XXXX'
                DEPLOYABLES: 'target/appengine-staging/app.yaml'
                VERSION: 'XXXX-${BITBUCKET_BUILD_NUMBER}'
                PROMOTE: 'true'
                STOP_PREVIOUS_VERSION: 'true'
                EXTRA_ARGS: '--verbosity=debug'
    

```

I want to replace `maven:3.8.3-openjdk-11`  with `maven:3.8.3-openjdk-17` or some such but cannot find an image that contains Java 17, Python 3, and Maven.
