Dawid Weiss commented on LUCENE-3973:
-------------------------------------
bq. Unless you run into the same taskdef/classloader/sub-build/permgen-OOM
I was just saying to fetch them via ivy and then spawn a separate jvm to run
them, much like you'd do anyway if they are separate installations.
Besides -- we already have an 'ivy warning with instructions', the same can be
done with permgen/OOM problems -- detect the current (ANT's) VM's settings (can
be done via mx bean) and warn/ fail the build if the defaults are too low,
instructing the user to set up ANT_OPTS properly...
I'm not pressing on this, this is a no-issue.
> Incorporate PMD / FindBugs
> --------------------------

> Key: LUCENE-3973
> URL: https://issues.apache.org/jira/browse/LUCENE-3973
> Project: Lucene - Java
> Issue Type: Improvement
> Components: general/build
> Reporter: Chris Male
>
> This has been touched on a few times over the years. Having static analysis
> as part of our build seems like a big win. For example, we could use PMD to
> look at {{System.out.println}} statements like discussed in LUCENE-3877 and
> we could possibly incorporate the nocommit / @author checks as well.
> There are a few things to work out as part of this:
> - Should we use both PMD and FindBugs or just one of them? They look at code
> from different perspectives (bytecode vs source code) and target different
> issues. At the moment I'm in favour of trying both but that might be too
> heavy handed for our needs.
> - What checks should we use? There's no point having the analysis if it's
> going to raise too many false-positives or problems we don't deem
> problematic.
> - How should the analysis be integrated in our build? Need to work out when
> the analysis should run, how it should be incorporated in Ant and/or Maven,
> what impact errors should have.
