Hi, I just build "flink-streaming" and avoid the problem. I guess, that the issue is related to the module structure and dependencies. "flink-streaming-examples" uses org.apache.flink.streaming.util.StreamingProgramTestBase (that is defined in "flink-streaming-core/src/TEST"
From my understanding, maven does not support dependencies into src/test but only into src/main (maybe I am wrong about this). I would suggest, to move StreamingProgramTestBase into a new module "flink-streaming-testUtils" (into src/main) and change the dependency of flink-streaming-examples accordingly. Why the build work on the parent-project, is still a riddle to me... But it seems that the dependency into scr/test can be resolved for this case. -Matthias On 02/25/2015 06:12 PM, Dulaj Viduranga wrote: > Hi, > Were you able to solve this?
