I agree that the quickstart docs/pom are lacking in this regard and have
filed FLINK-8654 <https://issues.apache.org/jira/browse/FLINK-8654>.

Hi
Thank you. It works now J
Maybe strict syntax of the “flink run” –command could be added to the
sample project ?

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>
-->

Hi
For example I don’t find WordCount.jar ! Or is it included in some
other jar ?

Hello,
What exactly is not working? What you've shown looks fine to me.
The following isn't due to your setup, and in this case can be
safely ignored:
[WARNING] com.data-artisans:flakka-slf4j_2.10:2.3-custom requires

[WARNING] org.clapper:grizzled-slf4j_2.10:1.0.2 requires scala

Hi
I have tried sample project from:

Linux: DISTRIB_DESCRIPTION="Ubuntu 16.04.3 LTS"

I tried to use Maven archetypes and the quickstart script.
After command: |mvn clean package -Pbuild-jar|

Do I need to something with IDE ? (IntelliJ IDEA)
Or do I need to install special version of Scala or something
like that ?
