Re: [platform-ant-dev] Fixing Ant bug in a plugin?

["Kirk Wolf" <kirk@xxxxxxxxxxxx>]

Darin, 

The one line fix for the Ant bug was included in the bug report that we made:
 https://issues.apache.org/bugzilla/show_bug.cgi?id=45010

Steve Goetze, also of Dovetailed Technologies, found a slick way to patch the global 
Ant classpath using a plugin that implements a plugin lifecycle class.

He built this into a plugin that's available from here:
http://dovetail.com/downloads/misc/index.html

It includes the source code for the Eclipse lifecycle class that does the job.
You can use this plugin to fix the broken Ant 1.7.0 <modified/> selector, which hopefully 
they will fix in the next release of Ant.  It also demonstrates the technique for patching/overriding
other Ant classes by prepending an arbitrary jar to the Ant global classpath.

Hopefully this will help someone else who needs to fix an Ant bug in a way that is convenient to 
distribute to a bunch of Eclipse users.

There is an extension point (org.eclipse.ant.core.extraClasspathEntries) to add extra JARs to the Ant runtime classpath, but these JARs are added to the classpath after the Ant Home JARs.

I would encourage you to attach your fix to the Ant bug for inclusion in the next version of Ant.

 There's a nasty bug in Ant 1.7 that prevents the <ftp> <modified> tag from working properly.

 See: https://issues.apache.org/bugzilla/show_bug.cgi?id=45010

 The fix to this is very simple (changing one line in an Ant class).

 I'd like to package a patched Ant class into a jar and include that jar into a plugin that my users can use with Eclipse to simplify fixing this problem.

 - Can I do this with an extension point that adds the jar to the beginning of the Ant classpath?
 - Can I make the extension conditional on having the Ant 1.7 plugin?

 I'm a newbie to writing plugins, can anyone help me with the plugin.xml to do this?

 Thanks,
