Trouble running Findbugs

[Nig]

Hi,

I'm running findbugs on Linux using the following:
HOME=/a/path/to/findbugs-1.3.9
$HOME/bin/findbugs -textui -home $HOME -effort:max -sourcepath
$directory -xml -output $directory/findbugs.xml $directory
Where, $directory contains an absolute path.

Some errors are logged during the run. For example:
The following errors occurred during analysis:
Invalid class resource COM/ibm/db2os390/sqlj/custom/
DB2SQLJCustomizer.class in /tmp/findbugs9057142813947684417.zip:COM/
ibm/db2os390/sqlj/custom/DB2SQLJCustomizer.class

Also, I get a error using the plugin when drilling down on a file:
01 Copying the source file 'COM/ibm/db2/app/DB2Struct.java' from the
workspace to the build folder '/root/.hudson/jobs/iface static
analysis/builds/2011-06-29_11-45-10/workspace-files/3047fc19.tmp' on
the Hudson master failed.
02 Seems that the path is relative, however an absolute path is
required when copying the sources.
03 Is the file 'DB2Struct.java' contained more than once in your
workspace?
04 Is the file 'COM/ibm/db2/app/DB2Struct.java' a valid filename?
05 If you are building on a slave: please check if the file is
accessible under '$HUDSON_HOME/[job-name]/COM/ibm/db2/app/
DB2Struct.java'

I'm not familiar with DB2SQLJCustomizer.class or DB2Struct.java and
can't find them on disk.

Not sure if it's something I'm doing wrong ?

Thanks !

Seems that you are also checking some IBM classes contained in a zip
file. These classes do not have sources so my plug-in does not find them.

The best way would be to add a findbugs filter to ignore those classes,
see: http://findbugs.sourceforge.net/manual/filter.html

I couldn't find any zip files with IBM classes but I added the
filtering and it now works fine.

Many thanks Ulli !
