[jboss-dev-forums] [Design of JBoss Build System] - Ideas for JBoss Retro

[pgier]

I have a couple ideas for changes to JBoss Retro.

First, I'd like to move non ant specific stuff out of the ant.tasks package, so the command line interface part of Weaver would be moved to something like:
org.jboss.retro.cli
And other non-ant stuff would be moved into more appropriate packages.

Next, I'd like to move all runtime stuff into it's own package.
So for example

  | org.jboss.lang
  | org.jboss.util
  | 
Would be moved to

  | org.jboss.retro.runtime.lang
  | org.jboss.retro.runtime.util
  | 
This way  the separation between weaver and runtime is a little easier to see.  

Taking this a step further, I was thinking that these might be divided into:
org.jboss.retro.runtime.jdk14
and
org.jboss.retro.runtime.jdk15

This way, in the future, retro could support conversions from JSE 6 to 1.5 and/or 6 to 1.4.  A conversion from 6 to 1.5 would only need to use classes from the jdk1.5 runtime.

The last part is going to be more difficult and if it sounds like a bad idea, please let me know.  I'd like to modify the current ClassRedirectEditor to be more dynamic.  When the Weaver starts up, I would like it to build a map containing all of the classes and methods in the new runtime package (org.jboss.retro.runtime.jdk14).  Then the modified ClassRedirectEditor will search for all methods matching something in the map.  If it exists in the map, then just replace the jdk5 method with the jboss version.

So for example, if the ClassRedirectEditor finds a method like java.lang.Boolean.parseBoolean it will replace the call with the matching method org.jboss.retro.runtime.jdk14.Boolean.parseBoolean.

My plan is to start working on these changes after the SVN conversion, so that the folder changes are tracked.
