Hi
You probably still have the old version of that page cached in your
browser. A new corrected version of the page was deployed on June 4.
Check that the publish date matches.
You are correct that your checks should be added as a plugin dependency.

I'm using custom checks, I followed the procedure described on the web link
you gave me. Everything now works correctly.
Maybe I'm wrong but I think there's a mistake in this documentation: in the
pom.xml example, dependencies containing custom developed checks are placed
in the <build> <extensions> ... </extensions> </build> section. But when I
run maven with my dependencies configured like that, these dependencies are
not placed on the classpath and maven can't resolve my custom developed
checks. If I place my dependencies containing custom developed checks in the
<plugin> <dependencies> ... </dependencies> </plugin> section, it works
fine.

Are you using your own custom checks or provide a custom packagenames.xml
file? In that case see this page:

Thanks for the answer. So, I tried maven-checkstyle-plugin 2.2 and it
didn't
work either, but that's a good beginning to have the correct plugin
version...
In the xml checkstyle configuration file where modules are defined, i
tried
to change
<module name="TreeWalker"> by <module
name="com.puppycrawl.tools.checkstyle.TreeWalker">and it now works. I
don't
really understand why we have to specify the fully qualified name of this
class, because it works fine when not using maven.

The Checkstyle plugin version 2.1 uses Checkstyle 4.1. So you can't use
stuff from Checkstyle 4.3 in your Checkstyle configuration.
Version 2.2 of the plugin, which is being released as we speak, uses
Checkstyle 4.4. Start by giving that version a try.

Hi,
I'm trying to integrate a checkstyle report in a maven project, but I'm
facing a problem. The checkstyle report is based on a custom checkstyle
check module I developed.
I'm using maven 2.0.9, maven-checkstyle-plugin 2.1, and checkstyle 4.3
When I execute mvn checkstyle:checkstyle or mvn site, I get the
following
exception. I don't really understand why the TreeWalker can't be
instantiated.
Any help would be great!
