由于找不到符号错误，在 Heroku 中部署 Play Framework 应用程序失败

Question

我正在尝试使用 Java 中的 Play Framework 2.5 在 Heroku 中部署一个应用程序，但显然找不到旋转模板。我已经将所需的 classes_managed 文件夹添加到构建路径中，以便可以找到由于 sbt compile 生成的类。我错过了什么？我发现的问题是由于 mvn install 命令，我也在使用 mvn 编译器版本 3.5.1。感谢您的帮助，在此先感谢您。

我通过在 eclipse 中进入项目属性，禁用 maven 特性然后再次读取它来解决这个问题。
