将Apache公共依赖项添加到Play Framework 2.0

Question

我想导入org.apache.commons.io但我收到此错误:

[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 - 

玩找不到包org.apache.commons.io.我怎样才能添加apache作为依赖？

Answer 1

添加依赖项

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

   val appDependencies = Seq(
      // Add your project dependencies here,
     "commons-io" % "commons-io" % "2.4"
   )
   

2. 使用播放控制台检查依赖关系解决或不使用命令: play dependencies

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