DataflowRunner not working

So I'm implementing this Job in Apache Beam to run it ultimately in Dataflow. So I tested in with Direct Runner but when I change it to Dataflow Runner, it crashes:

I run my code with:

 mvn compile exec:java -Dexec.mainClass=com.lf.myApacheBeam.MemoryTestProject.MemoryTest -Dexec.args="--runner=DataflowRunner"

If I change Dataflow with Direct then my code works and runs.

The line where it crashes is:

Pipeline pipeline = Pipeline.create(options);

And my 'options' are declared as:

MemoryTestExtractOptions options = PipelineOptionsFactory.fromArgs(args)
        .withValidation()
        .as(MemoryTestExtractOptions.class);
    options.setStreaming(true);
    //options.setRunner(DataflowRunner.class);
    options.setTempLocation("gs://blahblahblah/temp/");
    options.setBigQuerySchema(TestResultToRowConverter.getSchema());

Finally my interface 'MemoryTestExtractOptions' is:

  private interface MemoryTestExtractOptions
      extends Options, BigQueryTableOptionsForMemoryTest, StreamingOptions, PubsubTopicAndSubscriptionOptions, DataflowPipelineOptions//, DataflowPipelineOptions
       {


    @Description("BigQuery table to write to, specified as "
        + "<project_id>:<dataset_id>.<table_id>. The dataset must already exist.")
    String getOutput();
    void setOutput(String value);
}

The error complains about 'DataflowPipelineOptions.setUserAgent' but I do not call it and I checked my options and they are all well formed. Am I missing something specific for Dataflow? Thank you.

Found the problem. My pom.xml was specifying the version of dataflow-runner, instead of matching ${beam.version}

I changed, and it worked like a charm.

Thanks for the hints that pointed me into the right direction

Please make sure that your pom.xml lists org.apache.beam:beam-runners-google-cloud-dataflow-java artifact as a dependency. If you generated your project using the beam-sdks-java-maven-archetypes-examples archetype, you can add -Pdataflow-runner to your maven commandline.

There is an example of this in the Beam Quickstart instructions under Dataflow: https://beam.apache.org/get-started/quickstart-java/
