I have created a Java request sampler using Jmeter 4.0. After packaging the jar using maven, I copied the jar file to lib/ext and I can see the class in java request. But, when I try to execute, I'm getting the below error. Can someone help me to understand what went wrong?
2020-06-19 12:38:01,265 WARN o.j.r.PluginManagerMenuItem: Failed to load plugin updates info
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
at sun.security.ssl.Alerts.getSSLException(Unknown Source) ~[?:1.8.0_241]
Also this is the way I have created the Java request.
The error you're getting is related to JMeter Plugins Manager not being able to connect to the JMeter Plugins Repository due to some problem with SSL certificates.
If you're behind a corporate proxy - you need to make JMeter aware of this proxy.
