Hello,

I've my pom.xml configured like

               <plugin> 
                        <groupId>org.codehaus.mojo</groupId> 
                        <artifactId>emma-maven-plugin</artifactId> 
                        <executions> 
                                <execution> 
                                        <phase>package</phase> 
                                        <goals> 
                                                <goal>emma</goal> 
                                        </goals> 
                                </execution> 
                        </executions> 
                </plugin> 

After kicking off build from Hudson, I noticed for some reason this plugin
didn't run properly. I mean i went work
$HUDSON_HOME/jobs/project_name/workspace/workspace_name/target/site, hudson
didn't create emma folder insdie 'site' folder. However if I run the kick the
build manually like mvn clean install it creates 'emma' folder inside site and
it has coverage.xml.

Since automatic build kick-off from hudson didn't create coverage.xml inside
target/site/emma, my build failed and console showing the following exception
trace. Any help in this regard highly appreciated.
