How to add dependencies to play framework using SBT

Question

I'm trying to add the following dependencies into my new play-framework project

https://mvnrepository.com/artifact/net.sf.json-lib/json-lib/2.4

so I add the following into build.sbt

libraryDependencies += "net.sf.json-lib" % "json-lib" % "2.4"

however, when I try to run the application ( ./activator run ) I get the following error:

[info] Loading project definition from /****/project

What am I doing wrong here?

EDIT NOTE:

just realised the Download ( JAR ) in https://mvnrepository.com/artifact/net.sf.json-lib/json-lib/2.4 doesn't work either,

could it be an issue with repository itself?

Answer 1

I found the problem,

the problem was I needed to add classifier to the line:

libraryDependencies += "net.sf.json-lib" % "json-lib" % "2.4" classifier "jdk15"
