Jenkins build number: accessing from called Java program

jenkins add build number to artifact
jenkins build user environment variables
jenkins/workspace environment variable
jenkins set environment variable from script
jenkins get next build number
jenkins reset build number
jenkins environment variables path
jenkins global environment variables

How can I access the Jenkins build number and job path from the called Java program into this program?

Background: during the Java program runs, I want to create a dynamic link with this program (pathtothecurrentbuild/log) to the log file of the current run as an information for the admins in case of trouble.

These list of environment variables can be easily accessed using below code.

System.out.println("Build Number:"+System.getenv("BUILD_NUMBER")); //BUILD_NUMBER - name of the environment variable

This will print the current build number. Same way you can access other variables also.
