I am trying to open a jmx file written with Apache JMeter 2.7 in the last release Apache JMeter 2.11. I am getting this errors log :

I am using the version 7.0.650.20 of JAVA. Does anyone have an idea why I could not open my file ?

Solution

You're using Third Party jmeter-plugins.org plugins.

You need to add the required jar in lib/ext so that it works.

Download plugins-manager.jar from here and put it into lib/ext directory, then restart JMeter.

Note you need to do it each time you upgrade your jmeter version !
