    Hi,

    For adding HTTP Sink connector to my event streams, I have cloned the git repo as mentioned in the connector catalog.

    git clone https://github.com/thomaskwscott/kafka-connect-http.git
    cd kafka-connect-http
    mvn package

    when I run mvn package command inside kafka-connect-http folder, getting below error:

    Hi @Santhosh Ramanathan- thank you for you question!
    Here's what I was able to gather from the team:

    The error message indicates that you either don't have a truststore or the CA cert in the truststore doesn't match the server containing the mvn artifact. Try to turn off SSL checks in maven, or you need to ensure that you have the CA cert in your truststore configured in your maven settings.
    One other possibility: In certain versions of Java 8 there was a problem with the CA Certificates within the JVM. This was fixed in a later version of java 8. This link describes the problem:https://ibm.github.io/event-streams/troubleshooting/pkcs12-keystore-java-client/
    If you still require assistance, please raise a ticket.

    I hope this information helps!
