CF推送工作得很好，在Bluemix上自动部署失败

我有一个Java maven项目，我使用cf push部署到Bluemix。效果很好。它有这样的清单:

    applications:
    - services:
      - Monitoring and Analytics-gm
      - somedb
      disk_quota: 1024M
      hosts:
      - someapp
      name: someapp
      path: target/someapp-0.0.2.war
      domain: mybluemix.net
      instances: 1
      memory: 512M
    

但是，当我将存储库推送到hub.jazz.net并启动构建和部署时，部署步骤失败了。我检查了构建步骤中的工件，并创建了war文件。

错误信息是:Server error, status code: 400, error code: 170004, message: App staging failed in the buildpack compile phase

我错过了什么?

您可以看到target/someapp-0.0.2.war是构建的，它是部署脚本

中引用的那个

我试着:

• no path: in manifest.yml
• path: target/someapp-0.0.2.war(适用于本地cf push)
• path: someapp-0.0.2.war
