I have an issue with findbugs not copying the source file in an m2 build
(single module jar project) the exception is below.

I thought this was recently fixed (I can't find any trace of this). I am
running Hudson 1.297 on WinXP with jdk 1.6.0 update 07 with the following
plugins

Hudson is a master only (no slaves)

Hudson Active Directory plugin 1.11
Hudson Checkstyle Plug-in 2.8
Hudson FindBugs Plug-in 3.7
Hudson Maven Release Plug-in Plug-in 0.2.0
Maven Integration plugin 1.297
Hudson MSBuild Plugin 1.1
Hudson PMD Plug-in 2.7
Hudson Task Scanner Plug-in 3.5
Unnamed - org.jvnet.hudson.plugins:viewVC:hpi:1.2 1.2
Hudson Violations plugin 0.7.3
Hudson Warnings Plug-in 2.6

<Details><![CDATA[

<p> Class names should be nouns, in mixed case with the first letter of each
internal word capitalized. Try to keep your class names simple and descriptive.
Use whole words-avoid acronyms and abbreviations (unless the abbreviation is
much more widely used than the long form, such as URL or HTML).
