I am looking for functionality where we have a directory with some files in it.

Whenever any one makes a change in any of the files in the directory, jenkins shoukd trigger a build.

Is there any plugin or mathod for this functionality. Please advise.

Thanks in advance.

Although slightly related.. it seems like this issue was about monitoring static files on system.. however there are many version control systems for just this purpose.

I answered this in another post if you're using git to track changes on the files themselves: 

#!/bin/bash

set -e

job_name="whatever"
JOB_URL="http://myserver:8080/job/${job_name}/"
FILTER_PATH="path/to/folder/to/monitor"

python_func="import json, sys
obj = json.loads(sys.stdin.read())
ch_list = obj['changeSet']['items']
_list = [ j['affectedPaths'] for j in ch_list ]
for outer in _list:
  for inner in outer:
    print inner
"

_affected_files=`curl --silent ${JOB_URL}${BUILD_NUMBER}'/api/json' | python -c "$python_func"`

if [ -z "`echo \"$_affected_files\" | grep \"${FILTER_PATH}\"`" ]; then
  echo "[INFO] no changes detected in ${FILTER_PATH}"
  exit 0
else
  echo "[INFO] changed files detected: "
  for a_file in `echo "$_affected_files" | grep "${FILTER_PATH}"`; do
    echo "    $a_file"
  done;
fi;

You can add the check directly to the top of the job's exec shell, and it will exit 0 if no changes detected.. Hence, you can always poll the top level of the repo for check-in's to trigger a build. And only complete a build if the files in question change.

I have not tried it myself, but The FSTrigger plugin seems to do what you want:

FSTrigger provides polling mechanisms to monitor a file system and trigger a build if a file or a set of files have changed.

If you can monitor the directory with a script, you can trigger the build with a HTTP GET, for example with wget or curl:

wget -O- $JENKINS_URL/job/JOBNAME/build
