After getting a small Maven demonstration project working within Jenkins, I attempted to add the static analysis reports, installing the Static Analysis Utilities and Collector and the Findbugs Plugin. I tried several settings but was never able to see a FindBugs report on the Jenkins build status page, and eventually noticed that the 'Maven-generated site' link disappeared from the left-hand side of my project links.

Ultimately I traced this down to: If "Publish Findbugs analysis results" is checked in the Build Settings area below "Add post-build step", no link is generated; if it is unchecked, the Maven web site link appears.

The log files are instructive: near the end of a successful build I see the following, which seems to show the web site tree copy to where Jenkins stores the web site:
00:01:02.137 [INFO] Cobertura Report generation was successful.
00:01:02.137 [INFO] Generating "CPD" report — maven-pmd-plugin:3.4:cpd

00:01:02.324 [JENKINS] Archiving site from C:\Program Files (x86)\Jenkins\workspace\VizCommon\target\site to C:\Program Files (x86)\Jenkins\jobs\VizCommon\site

Near the end of a failed build I see this instead

Note that I only enabled Findbugs reporting, even though Maven successfully generates the PMD and Cobertura reports (I had installed the Cobertura plugin but first disabled, then uninstalled it. I suspect the problem is with Findbugs (see PMD test below).

I thought this might be related to JENKINS-26923, which suggested a problem with common-io (although I believe my version of the SA tool includes that bug's fix); so I stopped Jenkins, renamed commons-io-2.2.jar and restarted; but re-running a "Publish Findbugs" build still presented the log4j and dom4j warnings and no web site.

I suspect (or hope) these errors are not only causing the Maven web site to not be published, but may be why I never saw a link to Findbugs reports.

I did also try the case where "Publish PMD analysis results" is checked (only, with the Findbugs box unchecked). In that case I saw the log4j warnings, but not the dom4j warnings; the web site did publish - and I also got a PMD link.
