It means that the certification path to the JMeter Plugins repository contains invalid certificate (for example you're behind the corporate proxy and this proxy injects a MITM certificate which is not known to Java / JMeter)

The solution would be:

  1. Identify the certificate which causes the problem, it can be done using OpenSSL tool
  2. Create a Java Truststore (the same OpenSSL tool can do this)
  3. Point JMeter to use this Truststore by setting javax.net.ssl.trustStore system property
