If you run linkcheck on a project and there is more than zero files with errors, then the resulting report is incomplete. The table that shows which files have errors and warnings is not shown. The reason for this is a bug in linkcheck.jsl and the jelly syntax. Testcase and patch coming soon. This link was helpful in finding the reason for the failure: http://mail-archives.apache.org/mod_mbox/maven-users/200506.mbox/%3Cc38ad92d0506212340686a5dcb@mail.gmail.com%3E Here's the stack trace I get: Links checked.
