Question

我有一个用Play和Scala编写的示例应用程序与Amazon DynamoDB交谈，我正在尝试将其部署到Heroku上。 Heroku只有部署Play应用程序或Scala应用程序的说明，但不能同时部署两者。我试图合并两者的说明，但是很短。我看到了这个错误，

另外，我是Java，Play和Scala的新手，但我熟悉在Heroku上部署Rails应用程序。

Answer 1

将com.typesafe.startscript:xsbt-start-script-plugin:0.3.0的版本更改为0.5.0（您已指定此依赖项的位置）或编辑build.properties文件以设置sbt.version=0.11.0。
