Dear Fop-Devs,
since this came up, here is a list of tools I use for software quality
checking (and all them them can check for generic list types). All of
them have Eclipse and maven plugins (and ant tasks, and ....)
Checkstyle: checkstyle.sf.net
(already configured in fop, so nothing needs to be done)
Findbugs: findbugs.sf.net
(very good - all its advices should be followed)
PMD: pmd.sf.net
(contains almost too many rules, some of them are debatable)
I'd be willing to set up reporting for these 3 tools, so that you can
check what they suggest. I usually try to follow of these rules when
creating new files.
