just download and extracted jmeter on my pc. when i do double click jmeter.bat, this error occurred An error occurred: class com.google.common.collect.AbstractMapBasedMultimap over rides final method setMap.(Ljava/util/Map;)V errorlevel=1 Press any key to continue . . . why the jmeter has to do with com.google.common.collect.AbstractMapBasedMultimap. any idea what is wrong with my environment? im using apache-jmeter-2.11 and java version "1.7.0_51" i have also extracted 5 plugins: standard set, extras with lib set, extras set, WebDriver set and Hadoop set. updated: i sort of found out the problem. It is because i din't extract the plugins in correct order. it must follow this order: Extras > ExtrasLib > Hadoop > Standard > WebDriver when extracting the plugins into jmeter directory. Then the jmeter can be started without error.
