<!--
This file is based on maven-checkstyle-plugin config/sun_checks.xml file.
Checkstyle configuration that checks the coding conventions based on:
- the Java Language Specification at
http://java.sun.com/docs/books/jls/second_edition/html/index.html
- the Sun Code Conventions at http://java.sun.com/docs/codeconv/
- the Javadoc guidelines at
http://java.sun.com/j2se/javadoc/writingdoccomments/index.html
- the JDK Api documentation http://java.sun.com/j2se/docs/api/index.html
- some custom relaxations of the rules above & best practices
Checkstyle is very configurable. Be sure to read the documentation at
http://checkstyle.sf.net (or in your downloaded distribution).
Most Checks are configurable, be sure to consult the documentation.
To completely disable a check, just comment it out or delete it from the file.
Finally, it is worth reading the documentation.
