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 scala version: 2.10.4

[WARNING] org.clapper:grizzled-slf4j_2.10:1.0.2 requires scala version: 2.10.3

    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 ?
