java在Play 2.2中使用Apache IO Commons

我正在尝试导入ApacheCommons IO 2.4来播放Framework 2.2。我在我的项目建设中有这个。sbt

libraryDependencies += "commons-io" % "commons-io" % "2.4"

当我运行play compile时,我得到一个错误

[error] impossible to get artifacts when data has not been loaded. IvyNode = commons-io#commons-io;2.2
[trace] Stack trace suppressed: run last *:update for the full output.
[error] (*:update) java.lang.IllegalStateException: impossible to get artifacts
when data has not been loaded. IvyNode = commons-io#commons-io;2.2

你知道这意味着什么以及如何纠正吗
