redfish4ktc commented on MCHECKSTYLE-104:
-----------------------------------------

Hi,
The default value for {{maxErrors, maxWarnings, maxInfos}} should be 0 to match with the default
value of [maxAllowedViolations|http://maven.apache.org/plugins/maven-checkstyle-plugin/check-mojo.html#maxAllowedViolations]
introduced by MCHECKSTYLE-113.
In the attached code, the values are {{Integer.MAX_VALUE}}

> Hey guys,
>   first of all let me thank you for the wonderful job that you all do.  Our company's
build process has rocketed a century forward after we replaced Ant with Maven.
>   We're currently trying to migrate from Maven1 to Maven2. We have a Jelly goal  in our
old M1 build that does similar job to "checkstyle:check" in M2,  but it verifies that a project
does not have more than {{X}} Checkstyle Errors *and* {{Y}} Checkstyle Warnings.  That was
not entirely possible to configure with M2, where one can choose to fail the build on more
than 0 Errors *or* Warnings, where 0 is not a configurable value in contrast with {{X}} and
{{Y}}.
> I have scribbled several changes in 
> {{/maven-checkstyle-plugin/src/main/java/org/apache/maven/plugin/checkstyle/CheckstyleViolationCheckMojo.java}}
> where I basically replaced the parameter {{violationSeverity}} with 3 new parameters
({{maxErrors}}, {{maxWarnings}}, {{maxInfos}}) allowing the user a more flexible configuration
 of checkstyle-inflicted build failures. 
> Example :
> The configuration
> {code:xml}
> <plugin>
>   <artifactId>maven-checkstyle-plugin</artifactId>
>   <configuration>
>     <failsOnError>true</failsOnError>
>     <maxErrors>0</maxErrors>
>     <maxWarnings>100</maxWarnings>
>      .....
>   </configuration>
> ......
> {code}
> will fail the build of a project that has more than 0 Checkstyle Errors or more than
100 Checkstyle Warnings.
> If you find such the feature useful and want to include it in some of the next releases
of {{maven-checkstyle-plugin}} I will be happy to do the additional Documentation/Test Cases.
