Ability to collect a bug total (and issue build failure) from findbugs results
in multi-module project
------------------------------------------------------------------------------------------------------
Key: MFINDBUGS-114
URL: http://jira.codehaus.org/browse/MFINDBUGS-114
Project: Maven 2.x FindBugs Plugin
Issue Type: Improvement
Affects Versions: 2.3.2
Reporter: Michael Yates
Attachments: FindbugsViolationCheckMojo_summary.patch
It would be useful for people who have existing code bases and a continuous
build environment to have the ability to establish a "baseline" number of bugs.
With the baseline established and configured any new bugs would cause a build
failure.
It is impractical in a large existing codebase to set up findbugs and fix all
errors immediately - so the existing findbugs behavior of hard fail on first
project with bugs is too harsh.
A softer approach is to set up findbugs with a threshold configured at the
current number of bugs. If findbugs fails when your total bugs exceeds this
value then new/changed will be less likely to introduce new bugs. Further the
"build master" can lower the threshold over time to improve the code in the
existing base.
I have included a patch to FindbugsViolationCheckMojo as a starting point to
solve the above problem. Note I have no experience in Groovy and very little
with authoring plugins. So the code is Java (complete with missing semicolons)
probably some of the ways I have done things are against the normal way of
doing things in plugins.
Hopefully the patch can serve as starting point to solve the above problem.
This type of issue seems to have some momentum in the wider community:
