Jason Gerlowski commented on SOLR-11946:
----------------------------------------
Attached is a patch that shows what this would look like on Linux. The
attached patch moves most arg-parsing logic to Java land, with some caveats:
- Haven't touched the "auth" tool yet. That tool is a little more complicated
and I needed a bit more time on it.
- The help text is currently generated from the commons-cli {{Option}} and
{{CommandLine}} classes. It doesn't look much like the current help text. If
this is something we want to preserve as close as possible, this will require a
bit more work (but is totally do-able).
- No changes included for the Windows ({{bin/solr.cmd}}) script.
Would love any feedback or suggestions anyone has. Otherwise, I plan to revise
this patch and add Windows support in the coming days.

> Currently, there is logic in three different places that parses arguments for
> the {{bin/solr}} scripts. There is logic in the scripts themselves
> ({{bin/solr}}, {{bin/solr.cmd}}), and there is logic in Java to parse the
> arguments sent by the scripts themselves ({{SolrCLI.java}}.
> This creates maintenance burden. It makes it easy for inconsistencies to
> creep into the scripts (see SOLR-11840). It adds work when
> adding/removing/modifying {{bin/solr}} script behavior. And it forces anyone
> hoping to improve the scripts to be conversant in both bash and Windows batch
> scripting.
> It would be a big help if _all_ the argument parsing was done on the Java
> side, and little or none was done in the scripts themselves. There are a few
> situations in which this is difficult, but in no cases is it impossible.
> We should move this logic into Java-land.
