Cause: the jar package is missing, but we don’t know which one is missing, so we can go to the official website to download the JMeter plug-in manager, let the manager automatically detect the necessary jar package when importing JMX files, and then click Install to download automatically.

1. JMeter plug-in manager download address: https://jmeter-plugins.org/install/Install/

2. Put the plug-ins in this folder

3. Restart JMeter, drag the script into, and you will be prompted to install

4. JMeter restarts and completes the script import
