CannotResolveClassException: com.blazemeter.jmeter.controller.ParallelSampler

[chris....@liazon.com]

I would like to use the Blazemeter Parallel Controller to bundle some asynchronous calls to more closely mimic browser behavior.

I'm trying to track the total time to load certain pages, and there are some long running calls that skew my numbers because they are running back to back instead of asynchronously. 

When I run in the Jmeter UI it seems to work fine, but it doesn't seem to work when I use the CLI.

My Jmeter version is 5.1 r1853635

Plugin versions:

jmeter-plugins-manager-1.3.jar

jmeter-bzm-http2-1.0.jar

Is there an additional setup step I'm missing to get this to work in NonGUI mode?

Error in NonGUIDriver java.lang.IllegalArgumentException: Problem loading XML from:<test name>.

It is running from same machine? Is only problem that you run GUI test from machine with plugins and CLI test from machine, where plugins are not installed?

I am running both on the same machine using the same installation of Jmeter. My theory was that this add-in was only designed to work in GUI mode as all the documentation only ever showed it being used in GUI mode.

I believe the problem I was having was with the tests I was trying to add the controller to. They were tests originally written in a much older version of Jmeter. I tried adding the controller to a newer test and it worked as expected.
