I have download/clone OTX-Java-SDK from github and set api key, but i am getting below error while running program or performing mvn install.

I don't understand why i am getting this issue. Is it program related or certificate related. Please suggest me the solution.

This seems like an environmental issue, perhaps your Java environment does not recognise the TLS certificate used to sign the web server you are trying to connect to?
