I have the same problem. I download the plugin and copy the jar-file into lib/ext folder. Then I restart JMETER, but the menu-entry is not visible.
Then I check the file: jmeter.log. This contains following error description:

What is the reason for this and how could I solve it
I used JMETER 5.0 (and also 4.0) and JAVA 1.8.0_171.
