Yes, the jar exists. Both the WordCount example and my custom jar.
I also just redownloaded and reinstalled flink 1.5.2 as I was thinking maybe a dependencies or something was missing... But still the same error... ________________________________ De : vino yang <yanghua1...@gmail.com> Envoyé : mardi 7 août 2018 09:01 À : Gary Yao Cc : Florian Simond; user@flink.apache.org Objet : Re: Could not build the program from JAR file. Hi Florian, The error message is because of a FileNotFoundException, see here[1]. Is there any more information about the exception. Do you make sure the jar exist?
