Are you up for the challenge ?

Create a build.bat file, and place it in ANEBuilder source folder. (The same folder where
the ANEBuilder.swf is ^_^).

There are 10 total arguments passed from ANEBuilder to the build script
All these paths are absolute.

• $1 = ADT – Path to adt.bat for compiling the ANE
• $2 = JAR_LIB – Path to where Android JAVA project is located, it can be either a JAR file or the Project folder, depending on parameter $10
• $3 = IOS_LIB – Path to iOS lib file. I believe it is either a .A or .M file
• $4 = SWC – Path to Flash Library SWC file. This file needs to be unzipped by the build.bat
• $5 = XML – Path to extension.xml file which is needed for compiling
• $6 = DESTINATION – Where the $4 (SWC) will be unzipped to and where the .ane will be placed
• $7 = ANE_NAME – Name for the ANE file
• $8 = CERT_PATH – Path to the .p12 certificate
• $9 = CERT_PASS – .p12 certificate password
• $10 = CREATE_JAR – This is used in OS X, ANEBuilder passes here variable “yes”  for the build script to create a JAR file from selected Android JAVA project. Dunno if that is doable in Windows. You can try

You might need to change some code in the Main.as file to make it fully working.
I believe when using file.nativePath method, windows has its own way of dealing
with absolute filepaths. Currently all path handlings are suited for MAC.
