我想导入org.apache.commons.io但我收到此错误：

[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。如何将apache io添加为依赖项？

Answer 1

添加依赖项

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

的依赖项

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关系已解决或未使用命令：play dependencies

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

将Apache公共依赖项添加到Play Framework 2.0
