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...

This could be easily fixed by using maven archetypes instead of building it manually. As a good starting point, do this in the command line to create you folder structure & initial pom:

mvn archetype:generate -DarchetypeRepository=http://repository.sonatype.org/content/groups/public -DarchetypeGroupId=org.sonatype.flexmojos -DarchetypeArtifactId=flexmojos-archetypes-application -DarchetypeVersion=3.5.0

I think you should use net.flexmojos.oss which has superseeded the org.sonatype.flexmojos with new versions up to 6.0.0 Most dependencies (except from adobe) can be found in central. You should mavenize FDK as explained in https://flexmojos.atlassian.net/wiki/display/FLEXMOJOS/Flexmojos+6.x
