Adding Apache common dependency to Play Framework

Question

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

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

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

Answer 1

To add the dependencies

1. Edit project Build.scala file : /project/Build.scala and add dependency for commons-io

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

2. using play console check dependency resolved or not use command: play dependencies

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