[jira] [Created] (SOLR-11946) Move bin/solr arg-parsing logic to Java

Jason Gerlowski created SOLR-11946:
--------------------------------------

             Summary: Move bin/solr arg-parsing logic to Java
                 Key: SOLR-11946
                 URL: https://issues.apache.org/jira/browse/SOLR-11946
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: scripts and tools
    Affects Versions: master (8.0)
            Reporter: Jason Gerlowski
             Fix For: master (8.0)


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.
