Play framework 2.0 unresolved dependencies

Question

I have created a scala project with play framework 2.0. The project compiles and runs fine both with sbt and play commands.

However, the problems started when I tried to add another play project as a dependency to my project, because I needed to reuse some of its classes. sbt compile succeeds, but play compile/run does not. They give me the following error:

sbt.ResolveException: unresolved dependency: name_of_old_project_play_dependency: not found

I am also not able to run the project with sbt run ; whenever I do a request to the play framework, I get a null pointer exception.

Is that because both the projects are play projects and maybe there is a conflict somewhere? Any insight would be appreciated!

Answer 1

Please be sure to view the play version since sbt (the build system play uses) may have different versions.

Please verify the build.properties and plugins.sbt play version.

A technique I use to solve unresolved dependencies is to check the links that sbt tries to access. I manually try to fetch the file by visiting the failed sites. I usually discover I have a version mishap.
