问题描述

我想导入org.apache.commons.io，但出现此错误:

i want to import org.apache.commons.io but i'm getting this error:

[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

播放找不到包org.apache.commons.io. 如何添加apache io作为依赖项?

Play can't find package org.apache.commons.io . How can i add apache io as a dependency ?

推荐答案

添加依赖项

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

val appDependencies = Seq(
   // Add your project dependencies here,
  "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，则mvnrepository.com允许您在SBT选项卡中复制适当的代码:

Tip: If you're not familiar with SBT syntax mvnrepository.com allows you to copy proper one in SBT tab: commons-io sample
