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

Answer 1

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 !

Answer 2

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

Answer 3

I am using JMeter 3.3 and answers above did not work for me.

SOLUTION:

1. Download plugins-manager.jar from https://jmeter-plugins.org/downloads/all/
2. Put plugins-manager.jar into jmeter/lib/ext
3. Restart jmeter
4. Open script, it will ask to download dependencies, press yes.
