use splineAgent as a Jar file

Hi
i tried to install the Agent Spline without Maven - but Upload of the a Jar FIile
i cloned the code from git and build it to a `spline-spark-agent_2.12.jar`
and installed library using Upload to Databricks
when i run the code
```scala
import scala.util.parsing.json.JSON
import za.co.absa.spline.harvester.SparkLineageInitializer._
import za.co.absa.spline.agent.AgentConfig
import za.co.absa.spline.harvester.postprocessing.AbstractPostProcessingFilter
import za.co.absa.spline.harvester.postprocessing.PostProcessingFilter
import org.apache.commons.configuration.Configuration
import za.co.absa.spline.harvester.conf.StandardSplineConfigurationStack
import za.co.absa.spline.harvester.HarvestingContext
import za.co.absa.spline.producer.model.ExecutionPlan
import za.co.absa.spline.producer.model.ExecutionEvent
import za.co.absa.spline.producer.model.ReadOperation
import za.co.absa.spline.producer.model.WriteOperation
import za.co.absa.spline.producer.model.DataOperation
import za.co.absa.spline.harvester.ExtraMetadataImplicits._
import za.co.absa.spline.harvester.SparkLineageInitializer._
```

I get error that it doesnt recognise the packages
can you please advise what is missing?
