macos - Typesafe Stack play-scala Unresolved 依赖关系示例 OSX Homebrew 安装

Question

重新安装了 scala、giter8、sbt (0.11.3) 和 maven，一切都正常。 brew doctor 显示了我通过手动安装 pcre 和 python 2.7 制作的已知 mod。当我获取 play-scala 模板并第一次运行它时，我在 slf4j 上得到以下 Unresolved 依赖

# sudo sbt run
...

手动运行清理、重新加载、更新:

# sudo sbt

防止这种情况的正确方法是什么？这些依赖项不应该在初始化期间下载吗？

谢谢!

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。随后一切正常。更新命令成功检索到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)
