Problem while configuring a new custom check

[KiranKumar]

Hi All,

I have one requirement to extend Checkstyle with custom checks for my project.

I have tried to run / configure  one example and it didn't get through.

Please find the details below.

Please find the Java source file which has been attached.

Configuration file is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<!-- <!DOCTYPE module PUBLIC "-//Puppy Crawl//DTD Check Configuration 1.2//EN" "http://www.puppycrawl.com/dtds/configuration_1_2.dtd"> -->
<!DOCTYPE module PUBLIC "-//Puppy Crawl//DTD Check Configuration 1.2//EN" "D:/configuration_1_2.dtd">
<module name="Checker">  
  <module name="TreeWalker">    
    <module name="ThrowsRException"/>
   </module>  
</module>

The command i have used to run the example is:

java -classpath D:\checkstyle-5.0\checkstyle-all-5.0.jar com.puppycrawl.tools.checkstyle.Main -c D:\PluginsWorkspace\Plugin\src\com\abc\plugin\custom_check.xml D:\PluginsWorkspace\Plugin\src\com\abc\plugin\TestCaseException.java

And finally the error log is:

Unable to create Checker: cannot initialize module TreeWalker - Unable to instan
tiate com.abc.plugin.ThrowsRException
com.puppycrawl.tools.checkstyle.api.CheckstyleException: cannot initialize modul
e TreeWalker - Unable to instantiate com.abc.plugin.ThrowsRException

Please let me know if anyone has any clue.
ThrowsRException.java
P.S. I hope that it is a configuration problem OR the way i have been trying to run the Check is a problem.

Thanks and Regards
