[news.eclipse.platform] External Plug-in Modification

["Bob" <bsagusti@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hello,

I'm new to Plug-In development. All I've done is built some test plugins 
like "Hello World" and such.

The reason I'm looking into this is that our eclipse installation has an ftp 
client and my target has changed port numbers. I've found the file FTP.java 
down in a source tree under org.apache.ant_1.5.3 . This file defines the 
standard port of 21 for the ftp port. I simply desire to change this port 
number and re-build, create the .jar and put it into my plugins directory 
under my eclipse installation so that my client will have a different port 
number. I'm having trouble building this source though.

First off, can this be done with external plugins that come with the 
installation. I figured that if the source comes with it, then it can be 
built, but I noticed a line in the PDE guide under the Fragments section 
that says:

"Since external plug-ins cannot be changed inside the workbench, the 
environment inherently supports the fact that the fragment should be 
developed without modifying its target plug-in. "

When I import the plugin by Import->External Plug-ins and Fragments
And then select the ant plugin with added required plugins and choose 
extract source (because the source in zipped) It build with a ton of errors.

Any word of wisdom on this one would be greatly appreciated.

Thanks,

Bob
