  a) Adding new dependencies:

  b) Build a jar for running on the cluster:
  There are two options for creating a jar from this project
- b.1) "mvn clean install" -> this will create a fat jar which contains all dependencies necessary for running the jar created by this pom in a cluster. The "maven-shade-plugin" excludes everything that is provided on a running Flink cluster.
- b.2) "mvn clean install -Pbuild-jar" -> This will also create a fat-jar, but with much nicer dependency exclusion handling. This approach is preferred and leads to much cleaner jar files.
