[jira] [Created] (UIMA-2686) Derive DUCC_HOME from the location of executable jars in CLI.

Jim Challenger created UIMA-2686:
------------------------------------

             Summary: Derive DUCC_HOME  from the location of executable jars in CLI.
                 Key: UIMA-2686
                 URL: https://issues.apache.org/jira/browse/UIMA-2686
             Project: UIMA
          Issue Type: Task
          Components: DUCC
            Reporter: Jim Challenger
            Assignee: Jim Challenger


The scripting currently derives the location of DUCC_HOME based on where it is invoked from.  When using the API the invoked code should do the same thing, based on where it is invoked from.

A search-order is established:
  1) search environment for DUCC_HOME
  2) look in system properties (-DDUCC_HOME)
  3) infer DUCC_HOME from the location of the jar file the API is invoked from

If DUCC_HOME is not found in any of these places, throw and fail.
