Checkstyle configuration that matches the Eclipse formatter

Checkstyle is very configurable. Be sure to read the documentation at

http://checkstyle.sourceforge.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.
