cant see row numbers in findbugs report

[plueschmuetze]

hey folks,

i am using findbugs and hudson with hudson findbugs plugin. my problem is that i cant see the row number in the findbugs report. i can see the errors, warnings etc but not the row number where i can find the error, warning ... i am using findbugs on a jar file that i build in the following way:

<target name="BuildJar">
<jar destfile="${jarFile}"
basedir="${build}"
excludes="**/test.class"/>

the thing that makes me wonder is that when i use findbugs on another jar that i didnt build on my own (in my case it was bcel.jar from apache) i can see the line numbers.... ?????

can anybody help me?

thx in advance!!!!
