Please help me with the issue.

Hi Senthil,

I am not able to give you straight "fix the problem" answer but I will try to point directions:

• try to reuse dependencies that are part of JIRA api. I know for sure that there is apache httplcient. For sure it's older version than httpcomponents you included but I guess it should not be a problem. Similar story with xml-apis and xerces: try to rely on what is already in place.
  
  
• If you really want to bring these libraries, you can try excludes. Few people reported the same exceptions and looks like were able to overcome it: https://answers.atlassian.com/questions/27329453
