Heroku Play 2.x应用程序在本地运行，但因“0”而失败；下载失败“；论赫罗库

在本地运行应用程序时，一切正常。我甚至跑了

rm -r ~/.m2 

确保我重新下载了所有东西。然而，当我部署到Heroku时，Heroku报告说它无法下载commons编解码器。我不认为这是回购协议的间歇性问题，因为回购协议已经上升。（当然，这可能是Heroku的间歇性问题…）

我在谷歌上找不到任何我能理解的东西（我仍然有点不清楚sbt到底是如何工作的）。你知道我怎样才能在Heroku上重新站起来跑步吗

    resolvers += "repository.jboss.org-public" at "https://repository.jboss.org/nexus/content/groups/public",
    resolvers += "maven-restlet" at "http://maven.restlet.org"
)

当我添加rabbitmq时，问题开始出现，但即使在我尝试删除它时，问题似乎仍然存在。

我遇到了一个问题，建议我通过如下更改PlayProject函数来“修复”这个问题：

val main = PlayProject(appName, appVersion, appDependencies).settings(defaultScalaSettings:_*).settings(
    resolvers := Seq("typesafe" at "http://repo.typesafe.com/typesafe/repo"),
    resolvers += "spy" at "http://files.couchbase.com/maven2/",
    resolvers += "project.local" at "file:${project.basedir}/repo",
    resolvers += "repository.jboss.org-public" at "https://repository.jboss.org/nexus/content/groups/public",
    resolvers += "maven-restlet" at "http://maven.restlet.org"
)

我真的不喜欢这个，因为我不明白。我觉得我在解决Heroku的一个问题。有人能解释一下为什么这样做，为什么这样做是正确的（或不正确的）？

当我把回购协议推给Heroku时，我看到了同样的行为。奇怪的是，它只尝试“Typesafe发行库”，而不尝试其他版本。当我将我的回购推给Heroku时，我看到了同样的行为。奇怪的是，它只尝试“类型安全版本存储库”，而不尝试其他版本。
