java - 使用 Gitlab CI 将 Spring Boot 应用程序部署到 Google App Engine？

Question

我有一个 Spring boot 应用程序，我想通过 gitlab CI 部署到 Google App Engine。构建失败并出现以下错误:

错误:(gcloud.app.deploy) 要使用 java 的本地暂存，必须安装 Java 7+ JRE 并位于您的系统路径

下面是 gitlab-ci.yml 文件，需要修改该文件以包含 JRE 安装。我已经尝试了几乎所有通过网络可用的方法，包括使用 apt-get 包，还使用 ​​gcloud 安装 app-engine-java 但不打印 java -verison。有人可以修改这个 ci 文件来安装 jre 7+ 依赖项吗？

        ```
        image: google/cloud-sdk:alpine 
        deploy_production:
          stage: deploy
          environment: Production
          only:
          - master
          script:
          - echo $DEPLOY_KEY_FILE_PRODUCTION > /tmp/$CI_PIPELINE_ID.json
          - gcloud -q components install app-engine-java
          - gcloud auth activate-service-account --key-file /tmp/$CI_PIPELINE_ID.json
          - gcloud --quiet --project $PROJECT_ID_PRODUCTION --verbosity debug app deploy src/main/webapp/WEB-INF/appengine-web.xml```
