[jira] Commented: (UIMA-1176) JCasGen shouldn't generate types for imported type systems (or at least it should be an option)

["Tong Fin (JIRA)" <ui...@incubator.apache.org>]

    [ https://issues.apache.org/jira/browse/UIMA-1176?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12631614#action_12631614 ] 

Tong Fin commented on UIMA-1176:
--------------------------------

I think there are 2 ways to use "import" in UIMA descriptors:
1. easy to read the descriptor and easy to maintain and share across the descriptors
2. use someone else descriptor 

Adam's use-case is the case#2 and I think most people use case#1 more often than cas#2.
If we support this new feature request, I suggest that we make it as an "option" with the current behavior as the "default".

There are many use-cases to think about. For example:

<analysis engine descriptor>
    <import localtion="my_non_shared_type_system.xml">
</analysis engine descriptor>
<descriptor for my_non_shared_type_system>
   <import location="someone_else_shared_type_system.xml>
</descriptor for my_non_shared_type_system>

<analysis engine descriptor>
    <import localtion="someone_else_shared_type_system..xml">
</analysis engine descriptor>

> Our project reuses a common type system that we got from a different source.  The common type system descriptor is imported into our main type system descriptor.  The common type system has its own JCas types, in a jar file.  
> When we generate JCas types for our main type system descriptor, it currently generates all of the classes for all of the imported type systems as well.  We don't want this behavior, so we have to manually go through and delete those classes.
> I think JCasGen should only generate types for the type system descriptor that you run it on, not on imported type system descriptors.
