Checkstyle configuration that checks the sun coding conventions from:
|
||||
|
||||
- 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 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.
