在Play Framework 2.0中添加Apache公共依赖

Question

我想导入org.apache.commons.io，但是我得到了这个错误：

[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] /home/ghost/Bureau/app/play-2.0.1/waf/app/controllers/Application.java:41: error: cannot find symbol
[error]                 FileUtils.copyFile(file, destinationFile);
[error]                 ^
[error]   symbol:   variable FileUtils
[error]   location: class Application
[error] 2 errors
[error] {file:/home/ghost/Bureau/app/play-2.0.1/waf/}waf/compile:compile: javac returned nonzero exit code
[error] application - 

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

Answer 1

添加依赖项

1. 编辑项目Build.scala文件：/project/Build.scala并为commons-io添加依赖项

val appDependencies = Seq( //在此处添加您的项目依赖项，"commons-io“% "commons-io”% "2.4“)使用播放控制台检查依赖项已解决或不使用命令：play dependencies

提示:如果您不熟悉SBT语法，mvnrepository.com允许您在SBT选项卡中复制适当的语法：commons-io sample
