SBT not adding unmanaged JARs

Question

Hey I am trying to sbt compile a Scala project with 2 external .jar libraries as dependencies. I've added them in the /lib folder and I can see they are recognized by sbt when I run "show unmanagedClasspath" I see the 2 jars. However when I run "sbt assembly", sbt tries to resolve dependencies and fails when it can't download the libraries that are already there.

Answer 1

You don't need to add the jars that you've in the \lib directory again in libraryDependencies. libraryDependencies is part of your managedClasspath and everything in lib directory is part of your unmanagedClasspath, both together forms your dependencyClasspath.

You can see this by typing this on sbt prompt and checking the dependencies section:

inspect externalDependencyClasspath

In this case 'external' just means dependencies that are external to the project (ie not internal project dependencies)
