When adding the sbt-start plugin to push to Heroku, via build.sbt with the following contents: 

resolvers += Classpaths.typesafeResolver

addSbtPlugin("com.typesafe.startscript" % "xsbt-start-script-plugin" % "0.5.3")

I get an unresolved dependency with play:

[warn]  module not found: play#sbt-plugin;2.0.4

Which is weird considering that if we remove the sbt-start-plugin, we can actually find the play plugin with no problems.

EDIT

Maybe its related to this specific version of the plugin? https://github.com/sbt/sbt-start-script/issues/23

删除sbt-start-plugin允许play#sbt-plugin;2.0.4被发现是很奇怪的，因为我相信这play#sbt-plugin;2.0.4仅适用于 Scala 2.9.1 和 SBT 0.11.3。也许当您添加时，sbt-start-plugin您还更改了 Scala 或 SBT 版本？

尽管如此，与将其他 Scala Web 框架部署到 Heroku 不同，sbt-start-plugin将 Play 2.0 应用程序部署到 Heroku 应该没有必要，因为Play 2.0 已经包含所需的stage任务，因此部署到 Heroku 应该开箱即用。如果您使用新的 Play 2.0 应用程序，您可以将其部署到 Heroku，而无需进行任何修改。
