Hi guys,
I am facing following error message in flink scala JDBC wordcount.
could you please advise me on this?
*Information:12/10/2016, 10:43 - Compilation completed with 2 errors and 0

<!--
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.
