FindBugs Exclude filter with Ant - ant

Question

I can't get FindBugs to take into account my exclude filter:
In tools/findbugs-exclude.xml:
<FindBugsFilter>
<Match>
<Bug pattern="WMI_WRONG_MAP_ITERATOR,SE_COMPARATOR_SHOULD_BE_SERIALIZABLE,RV_RETURN_VALUE_IGNORED,EI_EXPOSE_REP,EI_EXPOSE_REP2,MS_CANNOT_BE_FINAL,SBSC_USE_STRINGBUFFER_CONCATENATION,SE_BAD_FIELD"/>
</Match>
</FindBugsFilter>
In build.xml:
<findbugs home="${findbugs.home}"
output="html"
outputFile="${findbugs.output.current}"
timeout="1200000"
jvmargs="-Xmx1024m"
effort="max"
excludeFilter="${basedir}/tools/findbugs-exclude.xml">
<auxClasspath>
<fileset dir="${basedir}/lib">
<include name="**/*.jar" />
</fileset>
</auxClasspath>
<sourcePath path="${basedir}/sources" />
<class location="${classes}" />
<fileset dir="${basedir}/build/dist">
<include name="*.jar" />
</fileset>
</findbugs>
FindBugs generates the report properly but it includes everything.

I've had the exact same problem and it was due to a typo in the findbugs-exclude.xml file path.
Try running ant in verbose mode like this:
C:\Workspace\example> ant -verbose
You'll notice something like this in the output:
findbugs:
[findbugs] Executing findbugs FindBugsTask from ant task
[findbugs] Running FindBugs...
[findbugs] Executing 'C:\Workspace\opt\Java\jdk1.8.0_72\jre\bin\java.exe' with arguments:
[findbugs] '-Xmx1024m'
[findbugs] '-Dfindbugs.hostApp=FBAntTask'
[findbugs] '-Dfindbugs.home=C:\Workspace\opt\findbugs-3.0.1'
[findbugs] '-classpath'
[findbugs] 'C:\Workspace\opt\findbugs-3.0.1\lib\findbugs.jar'
[findbugs] 'edu.umd.cs.findbugs.FindBugs2'
[findbugs] '-sortByClass'
[findbugs] '-timestampNow'
[findbugs] '-xml:withMessages'
[findbugs] '-exclude'
[findbugs] 'C:\Workspace\example\tools\findbugs-exclude.xml'
[findbugs] '-auxclasspathFromInput'
[findbugs] '-sourcepath'
[findbugs] 'C:\Workspace\example\src'
[findbugs] '-outputFile'
[findbugs] 'C:\Workspace\example\output\findbugs.xml'
[findbugs] '-exitcode'
[findbugs] 'C:\Workspace\example\cls'
If the -exclude argument is missing add the following to your build.xml to see if the path is correct:
<available property="file.exists" file="${basedir}/tools/findbugs-exclude.xml"/>
<echo>${basedir}/tools/findbugs-exclude.xml exists = ${file.exists}</echo>
Because FindBugsTask.java contains a check to see if the excludeFilter file exists.
public void setExcludeFilter(File filterFile) {
if (filterFile != null && filterFile.length() > 0) {
this.excludeFile = filterFile;
} else {
this.excludeFile = null;
}
}
