Will you please tell me how to set custom phpmd ruleset file in netbeans 8.1?

I'm installing phpmd into netbeans and it gives me error also but what if I want to set my custom ruleset file in netbeans 8.1?

I got the answer.....
After creating custom standard file using link
place this file to [main][usr/share/data/PHPMD/resources/rulesets]
I make file custom standard rules file name with [bold][customPHPMD.xml]

for that I Write some command on terminal

cd usr/share/data/PHPMD/resources/rulesets
sudo nano customPHPMD.xml
sudo chmod 777 cusomtPHPMD.xml

<?xml version="1.0"?>
<ruleset name="My first PHPMD rule set"
         xmlns="http://pmd.sf.net/ruleset/1.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0
