Any idea for the following:

If I use command line to compile my custom code functions properly:

javac -classpath "C:\Program Files (x86)\InstallAnywhere 2015\IAClasses.zip" com\mycc\*.java --> class files are good

If I use ANT javac task to compile my custom code does not function:

<javac srcdir="com\mycc" classpath="C:\Program Files (x86)\InstallAnywhere 2015\IAClasses.zip" /> --> class files don't seem to be good

If i compare the class files - i expect them to identical - however they are not, the class files from the command line javac seem to some more info in them.

Is it something to do with: "C:\Program Files (x86)\InstallAnywhere 2015\IAClasses.zip" ?
