Very much possible. You can use the environment variable, BUILD_NUMBER for that in execute shell section. To get a list of all the environment variables that one can use, go to 

<your_jenkins_url>/env-vars.html

For example:

http://my-jenkins-box:8080/env-vars.html

Logic that I spoke off in my below comment

if [ -z ${JOB_URL} ]; then
   echo "*************************** This is not a Jenkins build ***********"
   # Do your stuff here :)
else
   echo "**************************** This is a jenkins build so maven project is built before this script is executed via Jenkins ***************************"
fi

Also, remember that if you are running your script with sudo, these environment variables will not be available then

yes, it is possible. There is environment variable BUILD_NUMBER. What you mean by "Jenkins job configure section"? In "Execute Windows batch command" in (build section) you can do:

echo %BUILD_NUMBER%

to get this number in a different variable:

set "BUILD_NO=%BUILD_NUMBER%" echo %BUILD_NO%
