I am using the build file below to create fat swc. The swc file was successfully created, but all the PNGs in my asset folder are added directly to the ROOT folder in the swc. For instance

SWCLIb
     -catalog.xml
     -docs
     -library.swf
      image1.png
      image2.png

Is there any way to create a swc but instead of adding the PNGs directly to the root have the following directory structure inside the swc

SWCLIb
     -catalog.xml
     -docs
     -library.swf
     - ASSETS_FOLDER
                  -image1.png
                  - image2.png

Thanks

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath group: 'org.gradlefx', name: 'gradlefx', version: '0.6'
       
    }
}

apply plugin: 'gradlefx'

type = 'swc'
srcDirs = ['src/']
resourceDirs = ['assets/']

asdoc.outputDir = 'api' //will create the documentation in the %projectdir%/documentation folder
fatSwc = true
frameworkLinkage='external'

dependencies {
external fileTree(dir: 'lib/', include: '*.swc')

}
