Problem is described here:
https://confluence.atlassian.com/display/CLOVERKB/A+%3Cfiles%3E+with+%3Cincludesfile%3E+or+%3Cexcludesfile%3E+ignores+patterns
Add validation against non-trimmed patterns for <clover-setup> / <clover-report> and other tasks and print warnings if any are found (just a warning - do not fail a build).
