Java library dependencies not found in my Play2 scala application

Question

I have a play2 scala app where I need to do some ftp operations. Since I have previously worked with org.apache.commons.net I thought why not reuse some knowledge and implement this in my play2 scala app.

I added the dependency:

val appDependencies = Seq(
    "org.reactivemongo" %% "play2-reactivemongo" % "0.8",
    "commons-net" % "commons-net" % "3.2"
  )

Check the dependencie with play dependencise:

+--------------------------------------------------------+--------------------------------------------------------+-----------------------------------------+
| Module                                                 | Required by                                            | Note                                    |
+--------------------------------------------------------+--------------------------------------------------------+-----------------------------------------+
| commons-net:commons-net:3.2                            | importer:importer_2.10:1.0-SNAPSHOT                    | As commons-net-3.2.jar                  |

look fine. Updated my project with play clean compile and then play idea but it still can't find the libs. When doing import org.apache.commons.net.ftp.FTPClient;, .net is not found. I guess I have forgotten something. But what?

Answer 1

Hmm this is very strange. As stated in the question i did play idea to regenerate my project but that didn't work. So I deleted all idea files and did play idea and viola the import org.apache.commons.net.ftp.FTPClient works like a charm!
