Jars in lib folder not picked up when deploying pl

Question

I have built an application based on play framework 2.0.3. I have placed some jars in lib folder (unmanaged dependencies) which are used in my application like suggested in How to put a JAR file in a Play 2 project and use it?

All is fine when I run it from my local machine with play run

But when this application is deployed to Heroku, these jars are not picked up. I get compilation errors where these jars are used.

I even tried adding dependencies.yml with below content

require:
    - play 2.0.3
    - provided -> myjar 1.0

repositories:
  - provided:
      type:       local
      artifact:   "${application.path}/lib/[module]-[revision].jar"
      contains:
        - provided -> *

But still it didn't work.

My Start script (Procfile) is :

web: target/start -Dhttp.port=${PORT} ${JAVA_OPTS} -DapplyEvolutions.default=true -Ddb.default.driver=org.postgresql.Driver -Ddb.default.url=${DATABASE_URL}

Can somebody throw some light on this problem ?

Since heroku uses git, make sure that you lib folder and all contained jars are properly managed by git, ie that they are not in your .gitignore file.
