我正在尝试在Heroku上部署Play Framework（Java）应用程序（v 2.4），但是当我执行命令git push heroku master时，我得到以下异常：

我已经搜遍了所有的解决方案，我找到了一些适用于其他人的东西，但在这种情况下却没有用。我尝试过以下方法：

  1. 将行project/play-fork-run.sbt添加到.gitignore文件。
  2. 删除文件play-fork-run.sbt。
  3. 将这些解析器添加到build.stb文件中： resolvers += Resolver.url("Typesafe Ivy", url("http://repo.typesafe.com/typesafe/ivy-snapshots"))(Resolver.ivyStylePatterns) resolvers += "Typesafe" at "http://repo.typesafe.com/typesafe/releases/"

    4. 但似乎没什么用，当我在localhost上编译并运行应用程序时，它运行得很好。

    有什么想法可以解决这个问题吗？

    非常感谢任何帮助！

这适用于localhost的原因是您可能在某个时刻运行activator，这会将违规依赖项下载到本地.ivy2缓存。但是在Heorku上，只有sbt运行，并且激活器中存在主要错误，该错误很长时间没有被修复，导致激活器和sbt之间的不同解析器。

听起来你已经遇到过这些报告，其中包含一些建议（主要是你已经尝试过的）：

潜在的问题是依赖于此：

addSbtPlugin("com.typesafe.play" % "sbt-fork-run-plugin" % "2.4.3")

仔细检查project/下的所有sbt文件，以确保这些依赖项不在其中任何一个。还要确保在推送到Heroku之前已经提交了Git存储库更改。

最后，如果你仍然卡住了，你可以切换到使用sbt-heroku plugin，它使用本地编译的资产并将它们部署到Heroku。这将一起避免这个问题。

另外，我建议你在Play mailing list上提出这个问题。这是一个长期存在的问题，我遇到了很多遇到它的人。 Typesafe的人们需要听取他们的用户关于这是多么猖獗的事情。

答案 1 :(得分：1)

对于Play应用，请确保以下情况属实：

  1. 删除<project root folder>/project/play-fork-run.sbt
  2. 删除<project root folder>/project/sbt-ui.sbt
  3. 从fork in run := true移除<project root folder>/build.sbt，除非您明确地希望它在那里。

    4. 另外：确保文件play-fork-run.sbt和sbt-ui.sbt位于您的.gitignore中，但尚未检入您的项目。

    如上所述，如果您继续看到问题，请删除以下行：

    addSbtPlugin("com.typesafe.play" % "sbt-fork-run-plugin" % "x.x.x")

    和

    addSbtPlugin("org.scala-sbt" % "sbt-core-next" % "x.x.x")

    来自项目中的所有插件引用。这些插件仅支持Activator UI，并且不为常规构建提供有用的功能。
