HOW TO INSTALL THIS CERTIFICATE INTO JRE CACERTS?

Before you proceed further do confirm you had located exactly that jre which is giving this error. Many times IDE uses jre which is bundled with it not system jre. In my case I pointed all my IDE to my system Java installation.

  1. use keytool.exe inside your jre bin folder.
  2. fire following command to place your certificate inside cacerts file

keytool -import -noprompt -trustcacerts -alias ALIASNAME -file
/PATH/TO/YOUR/DESKTOP/CertificateName.cer -keystore
/PATH/TO/YOUR/JDK/jre/lib/security/cacerts -storepass changeit

NOW YOUR PROBLEM IS RESOLVED! RESTART YOUR IDE AND CHECK RESULTS.
