Subject Re: Sample project does not work ?

The quickstarts do not generate separate jars, but only one that 
contains all the sample jobs as described here 
<https://ci.apache.org/projects/flink/flink-docs-master/quickstart/java_api_quickstart.html#build-project>.

To select a specific job from the jar when submitting a job you can use 
the "-c" switch:

|./bin/flink run -c <package>.WordCount ./<path to jar>|

Alternatively, uncomment the following section in the pom.xml, set your 
desired job class, and rebuild the jar.

                                     <!-- If you want to use ./bin/flink 
run <quickstart jar> uncomment the following lines.
                                         This will add a Main-Class 
entry to the manifest file -->
                                     <!--
                                     <transformers>
                                         <transformer 
implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>${package}.StreamingJob</mainClass>
                                         </transformer>
                                     </transformers>
                                     -->
