Uwe Schindler commented on LUCENE-9411:
---------------------------------------
I think, whenever we change release version, we have to add new warning types
and analyze how it fails.
I am sure the new warnings are less serious. It will be mostly stuff like
missing break in try.
I would like to figure out how Werror or is affected by doclint stuff.

> Moving this over here from SOLR-11973 since it's part of the build system and
> affects Lucene as well as Solr. You might want to see the discussion there.
> We have a clean compile for both Solr and Lucene, no rawtypes, unchecked,
> try, etc. warnings. There are some peculiar warnings (things like
> SuppressFBWarnings, i.e. FindBugs) that I'm not sure about at all, but let's
> assume those are not a problem. Now I'd like to start failing the compilation
> if people write new code that generates warnings.
> From what I can tell, just adding the flag is easy in both the Gradle and Ant
> builds. I still have to prove out that adding -Werrors does what I expect,
> i.e. succeeds now and fails when I introduce warnings.
> But let's assume that works. Are there objections to this idea generally? I
> hope to have some data by next Monday.
> FWIW, the Lucene code base had far fewer issues than Solr, but
> common-build.xml is in Lucene.
