Please don't post images of text as they are hardly readable and not searchable.

Instead paste the text and format it with `</>` icon. Check the preview window.

Apparently you are embedding Jackson within your plugin which you should not do.

I remove the Jackson dependency but the error just didn't go away!

Jackson is already provided by elasticsearch. Just don't add it.  
What is the error when you remove this dependency?
