retroweaver.jar
      (in plugins/Retroweaver/lib)

4. Announcement-
   Initial Plugin Central release.

5. Source Code-
   module: plugins/Retroweaver
   tag:    release-1_1

6. Descriptions-
Short Description-

plugin authors needing to use the Retroweaver library
to convert Java 1.5 bytecode to 1.4 compatable bytecode.

Long Description-
The Retroweaver plugin provides a single point of
dependency for plugins needing to use the Retroweaver
library. Retroweaver is a bytecode weaver that enables
you to take advantage of the new Java 1.5 language
features, while still retaining total binary
compatability with 1.4 virtual machines. Retroweaver
operates by transforming Java class files compiled by a
1.5 compiler into version 1.4 class files which can
then be run on any 1.4 virtual machine.

Hi Jeff,

The Retroweaver plugin is intended to be a single point of
dependency for plugin authors wanting to use Retroweaver,
similar in nature to the single dependency provided by the
JakartaCommons plugin:
http://plugins.jedit.org/plugins/?JakartaCommons

Retroweaver allows a plugin author to write code using JDK
1.5 syntax, like Generics, but create a jar that can be run
under JDK 1.4. Setting the target attribute of the javac
task to 1.4 will only work if the source code is 1.4
compatible.  JDK 1.5 bytecode won't run under JDK 1.4,
that's why the bytecode changing done by Retroweaver is
required.

I'm using Retroweaver for the RubyPlugin (to be released at
Plugin Central soon). But I didn't want to include
retroweaver.jar as a direct RubyPlugin dependency. Making a
separate RetroweaverPlugin allows for easier use by others.
It also allows us to make updates to the retroweaver.jar in
one place.

Rob

Rob,

Please help me, I'm confused.  Why is this plugin necessary?
 It doesn't appear to do anything other than provide a help
function for using Retroweaver.  

If you just want to make sure you are building to 1.4, can't
you just use the target attribute of on the javac task in
Ant? Or wil that only work if you are using 1.4 compatible
source code?

A plugin that doesn't do any work probably shouldn't be a
plugin.

Jeff
