我想导入org.apache.commons.io,但是我遇到了这个错误:
[info] Compiling 1 Java source to /home/ghost/Bureau/app/play-2.0.1/waf/target/scala-2.9.1/classes...
[error] /home/ghost/Bureau/app/play-2.0.1/waf/app/controllers/Application.java:9: error: package org.apache.commons.io does not exist
[error] import org.apache.commons.io.*;
[error] ^

[error] ^

[error] location: class Application
[error] 2 errors

Play找不到包org.apache.commons.io。 如何将apache io添加为依赖项?
