[dna-issues] [JBoss JIRA] Commented: (DNA-62) Sequence Java class files to extract the class structure with annotations

    [ https://jira.jboss.org/jira/browse/DNA-62?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12501670#action_12501670 ] 

Randall Hauch commented on DNA-62:
----------------------------------

Nice work.  

On first blush, it could sense to put both the classfile and source sequencers in the same project.  However, that would mean that if you just wanted a Java classfile sequencer, you'd have to depend on the Eclipse Java parser (which has more than a few dependencies).  It's not horrible, and I wonder how many people would use one sequencer and not the other.

Another option is to have the Java source sequencer depend on the Java classfile sequencer, since the former has a lot more (transitive) dependencies, and since the latter only has a few.  

A third option is to move the general reader code to a separate module, and to have both sequencer depend on it.  This is my least favorite.

> This use case comes from a discussion about starting up the Microcontainer, and the desire to have a single processor of the JAR files to extract into a centralized repository the runtime annotations.  Right now the annotations are scanned by each component/service that needs them.  This feature would obviate the scanning being done by each component/service.
> Consider using http://scannotation.sourceforge.net/ for doing the actual scanning.
