Can'；t将Play 2.2.2应用程序部署到Heroku

在尝试将Play 2.2.2应用程序部署到Heroku时，出现以下错误

我的proc文件如下所示：

我一直在到处寻找这个问题的解决方案，但类似问题的解决方案到目前为止对我没有帮助：S

更新：当我尝试在不指定构建包的情况下部署时，Heroku会尝试将其部署为Play 1.2.7应用程序，而不是真正的Play 2.2.2应用程序。显然，每次部署都会失败。这是我得到的输出：

解决了。出现了一个问题，Heroku无法使用当前项目结构部署我的项目。我的项目位于另一个文件夹中，并且必须位于根级别，Heroku才能成功部署该应用程序

正如heroku本身一样，子文件夹中不可能有项目

但是您可以使用git subtree参数将子文件夹推送到herokus根上

git子树推送——前缀子文件夹名heroku master

它在没有生成包的情况下工作。。。我之所以添加构建包，是因为Heroku一直试图将其部署为play 1.2.7应用程序，而实际上它是play 2.2.2应用程序。我试图强迫它将其部署为2.2.2。是的，这是我最不喜欢的Heroku特性之一。
