Play2.3.x，新建一个工程就比较头疼，sbt解析一大堆，很多都被墙了。使用GAE代理：
set HTTP_PROXY=http://localhost:8087 activator
还有sbt的包老找不到，估计是官方源出了问题：
sbt.ResolveException: unresolved dependency: com.typesafe.sbt#sbt-native-packager;0.7.4: not found
需要在project/plugins.sbt文件中增加一行：
resolvers += Resolver.url("bintray-sbt-plugins", url("https://dl.bintray.com/sbt/sbt-plugin-releases/"))(Resolver.ivyStylePatterns)
注意前后都要用空行隔开，否则会报格式错误。搞完之后，终于是把sbt的几个包给下下来了:
