[SOLVED] Maven, Flex build issue

I am new to Maven. I am trying to compile Flex using maven plug-in flexmojos. I am having hard time to get maven download files from public repository. Currently we do not have any company intranet repository. Maven always fails to download required files (eg: flex-framework) from repository. Initially I did not configure the proxy, but now I did. After that maven was able to communicate to the repositories but unable to download all the files. I did try deleting the 'repository' directory couple of times, and also tried re-installing maven software.

Because, it could not download the files I thought may be I should try copying the files manually into the default repository location (/.m2/repository) and did that. But still I get an error as below.

[ERROR] Failed to execute goal on project nuxi-nms-flex-stats: Could not resolve
dependencies for project nuxi:nuxi-nms-flex-stats :swf:1.0.0: The following artifacts 
could not be resolved: com.adobe.flex.framework:flex-framework:pom:4.1.0.16248,
com.adobe.flex .framework:playerglobal:0.swc:2:4.1.0.16248: Could not find artifact
com.adobe.flex.framework:flex-framework:pom:4.1.0.16248 in central 
http://search.maven.org/) -> [Help 1]

This error message is really frustrating me. I have also tried building a sample app from sonatype examples on how to build a Flex app. Even that fails with a similar message (this time it complained unable to download flex compiler)

My question is, am I doing anything wrong? What could be the issue here? Any help in this regard is appreciated.... Thanks...

Sorry for such a lengthy explanation...
