My project has dependency on an external jar. I have created a directory lib and have copied the jar file into it. This is my build.sbt:
lib
build.sbt
The trick is to figure out which lib directory to put your JAR in. You can do this by running the following in your sbt console: show unmanagedBase.
show unmanagedBase
If you don't see your project there, you can run show YOURPROJECT/unmanagedBase to find the correct lib path.
show YOURPROJECT/unmanagedBase
