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

Hi
I have tried sample project from:
https://ci.apache.org/projects/flink/flink-docs-release-1.4/quickstart/scala_api_quickstart.html#maven
Versions:
Linux: DISTRIB_DESCRIPTION="Ubuntu 16.04.3 LTS"
Maven: Apache Maven 3.3.9
Java: openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build
1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)
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 ?
