Buildr + Checkstyle

[Chris Adams]

Hi,

I am trying to integrate checkstyle with builder. Thus far, this is what I have 
come up with:
    task :checkstyle do
        begin
            ant('checkstyle') do |ant|
                rm_rf 'reports/checkstyle_report.xml'
                mkdir_p 'reports'
                
                ant.taskdef :resource=>"checkstyletask.properties", 
:classpath=>Buildr.artifacts(CHECKSTYLE).each(&:invoke).map(&:name).join(File::PATH_SEPARATOR)
                ant.checkstyle :config=>"buildconf/checkstyle.xml" do
                    ant.formatter :type=>'plain'
                    ant.formatter :type=>'xml', 
:toFile=>"reports/checkstyle_report.xml"
                    
                    ant.property :key=>'javadoc.method.scope', :value=>'public'
                    ant.property :key=>'javadoc.type.scope', :value=>'package'
                    ant.property :key=>'javadoc.var.scope', :value=>'package'
                    ant.property :key=>'javadoc.lazy', :value=>'false'
                    
                    ant.fileset :dir=>path_to(:src,:main,:java), 
:includes=>'**/*.java'
                end
            end
        end
    end   

However, the problem I'm having is that path_to(:src, :main, :java) is at the 
top-level parent directory (where my buildfile is located)… How would I make 
the ":dir" relative to the current sub-project that the user is within or if 
they are building from the root, all the sub-projects?

Thanks for any help/info you can provide.
