尝试将 Play framework 2.1.1 应用程序部署到 Heroku 时出错
Error when trying to deploying Play framework 2.1.1 app to Heroku
我有一个播放框架 2.1.1 java 应用程序，它在本地主机上运行良好。
我想部署到Heroku，所以跟着these instructions
一切顺利，直到我输入这一行：
$ git push heroku master
当我在 CMD 中输入这一行时，最后出现以下错误：
remote: [info] Compiling 1 Scala source to /tmp/scala_buildpack_build_dir
/.sbt_home/plugins/target/scala-2.9.2/sbt-0.12/classes...

我真的不知道该怎么办，有人能帮帮我吗？
谢谢
您似乎在尝试部署一个使用 Scala 2.9 的应用程序，它不支持 Java 8。但是 Java 8 是 Heroku 上的默认设置。
尝试添加一个 system.properties 文件到你的应用程序的根目录，并在其中放入以下代码：
java.runtime.version=1.7
然后将文件添加到您的 Git 存储库并像这样重新部署：
$ git add system.properties
$ git commit -m "Set JDK version to 7"
$ git push heroku master
