Re: Newbie: problem creating checkstyle report

Hi Nik,

I tried the following:

            <plugin>
                 <groupId>org.apache.maven.plugins</groupId>
                 <artifactId>maven-checkstyle-plugin</artifactId>
             </plugin>
and I got:

the command
mvn checkstyle:checkstyle
for versions 3.4  and 4.0-beta6
works fine

Any ideas?

Thanks,
 Volker
P.S.: I used Maven 2.0 for these outputs.

Hi Volker,

What error did you get when you ran mvn site:site? Please copy it here.

Thanks,

Hi,

I tried to generate a report for my first project.
(I used the Maven Quick Start Archetype.)
I added the following lines in the pom.xml
<project>
 ...
   <reporting>
      <plugins>
         <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-project-info-reports-plugin</artifactId>
         </plugin>
            <plugin>
                 <groupId>org.apache.maven.plugins</groupId>
                 <artifactId>maven-checkstyle-plugin</artifactId>
             </plugin>
       </plugins>
    </reporting>
</project>
(Maybe somone can explain me why the documentation uses this
groupId and artifactId is mentioned nowhere else in the documentation
but in the example together with an old version!?
http://maven.apache.org/plugins/maven-checkstyle-plugin/howto.html )
But I got an error message. I tried several versions (3.4, 4.0 beta 6, ...) with different 
errors.
I also tried
            <plugin>
                 <groupId>checkstyle</groupId>
                 <artifactId>checkstyle</artifactId>
             </plugin>
with no success.

Another problem is that I can call the goal directly via
mvn checkstyle:checkstyle but the configuration set in pom.xml
seems to be ignored.

BTW: I use Maven 2.0 but I also tried the 2.0.1 from the SVN

I appreciate any help and thanks in advance
 Volker

P.S.: I also tried to generate a report for findbugs without
any success.
