Solve placement of Scala runtime library.

Implementation idea

Provide a Camunda-owned, repackaged and shaded Scala Runtime artifact which is consumed by Scala FEEL Engine and Scala DMN Engine

• Shaded Scala Runtime artifact created with a Maven module/project
  • Add a dependency on org.scala-lang:scala-library in the version we need (e.g. 2.13.0)
  • Configure maven-shade-plugin to define relocation of “scala” to “camundajar.impl.scala”
• Configuration in the POMs of Scala FEEL and Scala DMN:
  • Configure maven-shade-plugin to
    • Define relocation of “scala” to “camundajar.impl.scala”
    • Define an <exclude>org.scala-lang:scala-library</exclude> in the <excludes> of the <artifactSet>
• Adjustments in the BPM Platform
  • Add a dependency on the new shaded repackaged Scala Runtime to “engine-dmn/feel-scala/pom.xml” (and to the DMN engine module using Scala)
  • Ensure the new Scala Runtime artifact is included in all distributions
