How to use snapshot checkstyle version in maven plugin

Base on knowledge from http://maven.apache.org/plugins/maven-checkstyle-plugin/examples/custom-developed-checkstyle.html#Configure_the_Checkstyle_Plugin_to_use_your_custom_checks

you can easily force to maven checkstyle plugin to use custom/snapshot/different version of Checkstyle library.
It is very useful for testing of new Checks and generating HTML report on big sources on checkstyle library that you want and not a default old Checkstyle version that is attached to plugin.

Build HTML report by "mvn site" command, or "mvn checkstyle:checkstyle".

to have different HTML reports (for each tested Check) over the same sources - just save index.html as index-MyCheck.html, and do report generation for each Check separately.
