downloading dependency in apache flink

[Pankaj Kumar]

i am trying to write a job, using maven project.

Job is working fine in my editor , but when i am running that job through flink command line its giving ClassNotFoundException exception . Its not to find dependency.

If i will create a jar , will flink download all its dependency before executing that jar. if not that how can we run one-jar.

Thanks

Hi Pankaj,

are you creating a fat jar when you create your use code jar? This can be done using maven's shade plugin or the assembly plugin. We provide a maven archetype to set up a pom file which will make sure that a fat jar is built [1].

I was using wrong method to create fat jar, 

after using  mvn clean install -Pbuild-jar i was able to execute code through flink command line.
