Maven job setup in Hudson. Maven project is multi-module. Maven checkstyle plugin executes under its default checkstyle:check lifecycle phase "verify". When executing the Maven build under CLI, checkstyle plugin correctly executes checkstyle:checkstyle and writes the checkstyle-result.xml under "target" folder as expected.
Other report plugins such as findbugs, pmd, emma are setup the same way and reports are created in Maven and picked up by Hudson plugins as expected.

Hudson checkstyle report was working using the same Maven build before I upgraded to latest analysis-core and checkstyle report plugin.
I can provide more information if necessary.

Thanks in advance
