I have a multi-module project with file findbug-exclude.xml in some of the
modules. The file is configured as a <excludeFilterFile> in modules' poms.
From the build log I can see that the findbugs plugin is copying exclusion
filters to the temporary directory but it only does that for the first file with
given name (only first file with the name findbug-exclude.xml is copied and then
used in all modules which have their own findbug-exclude.xml file).
My current workaround is to name all of the exclusion filter files differenlty.
I use ${artifactId}-findbug-exclude.xml
