Question

获得了scala，giter8，sbt（0.11.3）和maven的全新Homebrew安装，并且大部分都检查了所有内容。 brew医生通过手动安装pcre和python 2.7来显示我刚刚知道的模组。当我获得play-scala模板然后第一次运行它时，我在slf4j上获得了以下未解析的deps

# sudo sbt run
...

运行干净，重新加载，手动更新：

# sudo sbt

[info] Set current project to my_app (in build file:/Users/homedir/typesafe/my_app/)

防止这种情况的正确方法是什么？在初始化期间不应下载这些代码吗？

谢谢！

Answer 1

感谢this question我最终删除了〜/ .m2和〜/ .ivy2，然后进行了清理，更新，重新加载。一切顺利。 update命令成功检索到了slf4j：

[my_app] $ update
[info] Updating {file:/Users/homedir/typesafe/my_app/}my_app...
[info] downloading http://repo.typesafe.com/typesafe/releases/org/slf4j/slf4j-api/1.6.1/slf4j-api-1.6.1.jar ...
[info]  [SUCCESSFUL ] org.slf4j#slf4j-api;1.6.1!slf4j-api.jar (1481ms)
