This aside, maybe we should return to the idea of the generated code living in 
a separate source set?... one that is not subject to formatting, extra 
validations, etc? I see some benefit in keeping it neat but it's also, you 
know, generated code...

Personally I don't know the implications of this, it seems a bit difficult for 
my weak gradle kung-fu skills. On the other hand implementing the 
properties-based stuff, following Tomoko's lead for the per-module javadocs 
options, that's something i might be able to help with.

The problem is not just the generated code: there are 140 or some violations 
for just this one simple check. In general, enabling any check is a large 
effort if we want to fix 100% of the codebase. So if we can iterate per-module 
and fix them incrementally, we make progess.

> When working on PR [https://github.com/apache/lucene/pull/25,] we noticed 
> that some dead code is not being caught during static analysis in gradle 
> build, such as the *start* variable in the following code: 
> [https://github.com/apache/lucene/blob/a5996dbecd4a6b4147d961260711a2cb6aeab3d3/lucene/facet/src/java/org/apache/lucene/facet/FacetsConfig.java#L446-L456]
>  
> We may need to look at if additional javac compiler flag, or configuration 
> for *error prone,* should be added to catch such bug as well as other 
> potential ones.
