Hi all, When I tried specify the runner in command for the examples: mvn
exec:java -Dexec.mainClass=org.apache.beam.examples.WordCount
-Dexec.args="--output=wordcount.txt --runner=FlinkRunner"
The building was failed and got error message as:Failed to execute goal
org.codehaus.mojo:exec-maven-plugin:1.5.0:java (default-cli) on project
beam-examples-java: An exception occured while executing the Java class. null:
InvocationTargetException: Unknown 'runner' specified 'FlinkRunner', supported
pipeline runners [DirectRunner] -> [Help 1]
I am wondering if anyone got the same issue and how you solved it.
