Description

I want to add digital signature in existing PDF file. For that i just want to add empty signature field in pdf as per my desire location using Java. Once the new PDF file generated, we would apply digital signature externally by clicking on empty signature field which we design above.

I found some source code but it's with new empty PDF and i want to add in existing pdf. 

Kindly provide some sample code.

I have another query for gradle dependencies. 

how can i add dependencies in gradle, i already tried with this but it's not working

compile group: 'org.apache.pdfbox', name: 'pdfbox', version: '3.0.0-RC1'

Kindly suggest correct way to declare dependancy.
