Apparently project dependencies are not being packaged into the jar generated by:
sbt package
How can dependencies be included?

If you have JAR files (unmanaged dependencies) that you want to use in your project, simply copy them to the lib folder in the root directory of your SBT project, and SBT will find them automatically.
Solution. Create a directory layout to match what SBT expects, then run sbt compile to compile your project, sbt run to run your project, and sbt package to package your project as a JAR file. Unlike Java, in Scala, the file's package name doesn't have to match the directory name.
If you run sbt package , SBT will build a thin JAR file that only includes your project files. The thin JAR file will not include the uJson files. If you run sbt assembly , SBT will build a fat JAR file that includes both your project files and the uJson files.
Well, I use sbt-assembly plugin to create jar with dependencies,
(1) add sbt-assembly to projects/assembly.sbt
echo 'addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.8")' > project/assembly.sbt
(2) run sbt clean assembly to build the jar.
It will create ${name}-assembly-${version}.jar in target/scala-${scalaVersion}
(3) Only in case you get infamous de-duplicate error, use assemblyMergeStrategy as described in here

There's a project called onejar that will package a project and all its dependencies into a single jar file. There is an SBT plugin as well:
https://github.com/sbt/sbt-onejar
However if you're just looking to create a standard package (deb, rpm, etc.) there is sbt-native-packager:
https://github.com/sbt/sbt-native-packager
It can place all your dependencies into a Linux package and add the appropriate wrappers to load all your dependencies and start your program or service.
