To run the code, use the following example. Make sure to update --project, --stagingLocation, --output, and --tempLocation. You will also need to make sure that all the Google Storage buckets are in the same region (EU, US, etc.) .

mvn -Pdataflow-runner compile exec:java \
      -Dexec.mainClass=com.mehmandarov.beam.OsloCityBike \
      -Dexec.args="--project=rm-cx-211107 \
