Migration from maven to gradle

Question

We are migrating maven project to gradle. We have flex for front end and as requested we are migrating it as well using gradlefx. Have added the dependencies:

dependencies{
    classpath 'com.adobe.flex.framework:flex-framework:4.0.0.14159'
    classpath files("./libs/flex/parsley-core-3.0.0.swc")
    classpath files("./libs/flex/parsley-flex-3.0.0.swc")
    classpath files("./libs/flex/legacy-parsley-commands-2.5.0.swc")
    classpath files("./libs/flex/spicelib-commands-3.1.1.swc")
    classpath files("./libs/flex/spicelib-reflect-3.0.0.swc")
    classpath files("./libs/flex/spicelib-util-3.1.0.swc")
}

2.My mxml has contents like:

<?xml version="1.0" encoding="utf-8"?>
<Object xmlns:fx="http://ns.adobe.com/mxml/2009" 
xmlns="http://www.spicefactory.org/parsley">
<fx:Script><![CDATA[//some imports]]></fx:Script></Object>

However on build am getting following error.

[ant:java] Java Result: 1
FAILED

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task :Common_Components:compileFlex.

  java.lang.Exception: mxmlc execution failed: Loading configurationfile D:\Softwares\flex_sdk_4.6\frameworks\flex-config.xmlD:\Xyz\Workspace\Common_Components\src\com\abc\common\MenuContext.mxml(9): Error: Could not resolve to a component implementation. xmlns:presentation1="com.abc.helpframework.presentation.*">`

The same setup is working for other mxml file. I doubt with object tag, not very sure though.
