我有一个Play框架2.1.1 java app,它在localhost上运行良好。

我想将它部署到Heroku,所以我跟着these instructions

一切顺利,直到我进入这一行:

$ git push heroku master

当我在CMD中输入此行时,我在结尾处收到以下错误:

我真的不知道该怎么办,有人可以帮我吗?

看起来您正在尝试部署使用Scala 2.9的应用程序,该应用程序不支持Java 8.但是Java 8是Heroku的默认设置。

尝试将system.properties文件添加到应用的根目录,并将以下代码放入其中:

sortedResultsUsingProperty(..)

然后将文件添加到您的Git仓库并重新部署,如下所示:

java.runtime.version=1.7
