title: jmeter command line option doesnt pick my params
body: <p>Why my command below doesn't pick the values I give at runtime rather it takes from my JMeter test plan itself where I defined with option <code>${__P(param1,value)}</code></p>
  <p><code>&lt;path to jmeter bat&gt; -n -t &lt;jmx loc&gt; -l &lt;loc of result.csv&gt; -j &lt;path to jmeterlog&gt; -Gparam1=paramval1 -Gparam2=paramval2 -Gparam3=paramval3 -Gjmeter.save.saveservice.output_format=csv -Gjmeter.save.saveservice.output_format=csv -Gjmeter.save.saveservice.assertion_results_failure_message=true -Gjmeter.save.saveservice.data_type=true -Gjmeter.save.saveservice.label=true -Gjmeter.save.saveservice.response_message=true -Gjmeter.save.saveservice.successful=true -Gjmeter.save.saveservice.thread_name=true -Gjmeter.save.saveservice.time=true -Gjmeter.save.saveservice.response_message=true -Gjmeter.save.saveservice.successful=true -Gjmeter.save.saveservice.thread_name=true -Gjmeter.save.saveservice.time=true -Gjmeter.save.saveservice.connect_time=true -Gjmeter.save.saveservice.assertions=true -Gjmeter.save.saveservice.latency=true -Gjmeter.save.saveservice.connect_time=true -Gjmeter.save.saveservice.thread_counts=true -Gjmeter.save.saveservice.response_data=true -Gjmeter.save.saveservice.response_data.on_error=true -Gjmeter.save.saveservice.response_message=true</code> -Gjmeter.save.saveservice.samplerData=true -Gjmeter.save.saveservice.requestHeaders=true -e -o </p>
  <p>I am running this from jenkins. Why it is not picking up my parameters?</p>
