Switching flow for assets:precompile in case of Windows

Because of the character limitation on Windows Command Line, the existing CLASSPATH assignment was failing. The commandline was exceeding 17000 characters while the limit is ~8000. Spilting the commands into multiple line and echoing the CLASSPATH value from a file rather than having it as part of the command line.

Fixing CLASSPATH-TOO-LONG error on windows by using an intermediate 'pathing' jar

In Windows, CLASSPATH variable too has a limit along with the character limit of the Command Line. To bypass this entirely, I'm creating an intermediate jar that holds the classpath in its MANIFEST.MF that is formatted to fit the JAR specification.
