jmeter-maven-plugin

Im currently working on a jmeter based project running the tests using jmeter maven plugin. So far everything works until i've added perfmon plugins, adding them to get Transactions per second and Response Times over Time using the jmeter UI, following the instructions here Running it in maven now results to: [INFO] Error in NonGUIDriver java.lang.IllegalArgumentException: Problem loading XML from:'/Users/foo/Tools/src/platform-load-test/jersey2-load-test/target/jmeter/testFiles/JerseyAsync.jmx', missing class com.thoughtworks.xstream.converters.ConversionException: [INFO] ---- Debugging

I have a Jmeter project that is executed by Maven and is able to locate external Beanshell scripts by the path src/test/jmeter/external-scripts-dir/script1.bsh , but when I run Jmeter directly in the GUI on my computer the relative location doesn't work and the tests cannot be ran standalone. This forces me to run Jmeter from Maven. So, I have a project file located at a Maven layout location like C:\files\git\projectA\src\test\jmeter\Project.jmx but since I ran jmeter from its installation folder at C:\Jmeter2.12 , it cannot find the relative location of the external script I mentioned
