在我的承诺中我：

删除了控制器类：com.fractalemagic.Crashes

我尝试使用Activator在本地运行项目时遇到了同样的错误但在我运行activator clean之后它运行正常。

我在构建日志中注意到Heroku只编译代码：

-----> Running: sbt compile stage

根据：https://devcenter.heroku.com/articles/play-support#activation

它也应该清理。

在撤销提交后，我能够成功推送到Heroku。

Answer 1

您链接的文档似乎有点过时了。您需要通过设置环境变量SBT_CLEAN=true

来专门告诉heroku进行干净编译

如果你正在使用heroku toolbelt：

heroku config:set SBT_CLEAN=true -a your-app-name

Heroku Build Behavior

Answer 2

对我来说，我通过删除目标下的所有内容然后重新编译来解决问题。

从Play Framework中删除路由时推送到Heroku时出错
