------------------------------------------
Summary: Builds should regenerate all generated sources
Key: LUCENE-4335
URL: https://issues.apache.org/jira/browse/LUCENE-4335
Project: Lucene - Core
Issue Type: Improvement
Reporter: Michael McCandless
We have more and more sources that are generated programmatically (query
parsers, fuzzy levN tables from Moman, packed ints specialized decoders, etc.),
and it's dangerous because developers may directly edit the generated sources
and forget to edit the meta-source. It's happened to me several times ... most
recently just after landing the BlockPostingsFormat branch.
I think we should re-gen all of these in our builds and fail the build if this
creates a difference. I know some generators (eg JavaCC) embed timestamps and
so always create mods ... we can leave them out of this for starters (or maybe
post-process the sources to remove the timestamps) ...
