Hello Daniel,

i am trying to use the crap4j plugin under hudson. i integrated crap4j into our
ant script and the output is generated well (report.xml as well as the html report).

when i try to run crap4j (v 0.5) under hudson (1.279), we get error messages like:

...
BUILD SUCCESSFUL

when i tried to find the problem, i diffed the generated report from ant with
the report after the crap4j plugin under hudson and
i get differences in these lines:

1.) ant:
<stats>
<name>
Method Crap Stats
</name>
<totalCrap>
60036,00
</totalCrap>
<crap>
7,16
</crap>
<median>
2,00
</median>
<average>
7,16
</average>
<stdDev>
36,86
</stdDev>

2.) hudson:
<stats>
<name>
Method Crap Stats
</name>
<totalCrap>
?
</totalCrap>
<crap>
?
</crap>
<median>
2,00
</median>
<average>
?
</average>
<stdDev>
?
</stdDev>

i think this is the point where the plugin gets the errors.

when i copy the report from ant into crap4j output folder for hudson and run an
ant build with just the crap4j task again via hudson (without running tests,
just do the report), the report is modified with the "?" again.

in ant i use crap4j 1.1.6 to generate the report, the report is approx. 5 MBs of
size.

i'm not sure whether this is a defect in the plugin nor do i know what to do
else - maybe you have any ideas ?

best greets,
oliver
