		Execute "mvn clean package -Pbuild-jar"
		to build a jar file out of this project!

		How to use the Flink Quickstart pom:

		a) Adding new dependencies:
			You can add dependencies to the list below.
			Please check if the maven-shade-plugin below is filtering out your dependency
			and remove the exclude from there.

		b) Build a jar for running on the cluster:
			There are two options for creating a jar from this project

			b.1) "mvn clean package" -> 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 package -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.
