Error: Unable to resolve resource bundle "fiber" for locale "en_US".

Question

Hi all,
Im trying to create a resources.swf file for the purpose of dynamic localization of our application. However, I keep getting this error thrown when I try to run the ant script.
Im running Flash Builder 4, the sdk is Flex 4.5.1 with AIR 3.0 and a Windows 7-64 bit machine (just mentioning as a few posts associated it with the OS).
After searching some of the forum posts, ( http://forums.adobe.com/thread/606383)
1> I checked the eclipse.ini file and found the following lines already in there.
     -nl
     en_US
2> My compiler options already has -locale en_US specified.
3> I tried including the swc files as suggested in the referenced thread, both as a referenced library and by manually copying the swcs to the project, but neither of them helped.
     "import 2 swc folders (Under Properties -> Flex Build Path -> Library Path):
     /Applications/Adobe Flash Builder 4/plugins/com.adobe.flexbuilder.dcrad_4.0.0.272416/dcradSwcs/4.0/libs
     and
     /Applications/Adobe Flash Builder 4/plugins/com.adobe.flexbuilder.dcrad_4.0.0.272416/dcradSwcs/4.0/loca le"
Thanks in advance for your help.
My build.xml file looks as follows:
<?xml version="1.0" encoding="utf-8"?>
<project name="appName" basedir="." default="main">
          <taskdef resource="flexTasks.tasks" classpath="${basedir}/lib/flexTasks.jar"/>

Answer 1

I did import the swcs first as a referenced library, by
Project-> Properties -> Flex Build Path -> Library Path -> add swc folder.
Secondly, I manually copied the swcs from the folders at
1>
C:\Program Files (x86)\Adobe\Adobe Flash Builder 4 Plug-in\eclipse\plugins\com.adobe.flexbuilder.dcrad_4.0.0.272416\dcradSwcs\4.0\libs
files present: fds.swc, fiber.swc and serializers.swc
2>
C:\Program Files (x86)\Adobe\Adobe Flash Builder 4 Plug-in\eclipse\plugins\com.adobe.flexbuilder.dcrad_4.0.0.272416\dcradSwcs\4.0\locale
files present: fds_rb.swc, fiber_rb.swc and serializers_rb.swc
into the libs folder of my project .
