Passing property values with spaces to Ant

[Cyril Bouteille <Cy...@yahoo.com>]

Hi,

I'm trying to pass a bunch of property values to Ant for dynamic
variables in my build and I'm running into problems when these values
contain spaces. For example, when passing a list of options as value of
a property, Ant tries to interpret these options.

Here's a simple testcase:
cyril@wyvern:~/p4/hotwire/2.0/build> ant -Dvar="-op1 -op2"
Unknown arg: -op2

I tried a bunch of shell tricks such as:
cyril@wyvern:~/p4/hotwire/2.0/build> ant -Dvar='-op1 -op2'
Unknown arg: -op2
cyril@wyvern:~/p4/hotwire/2.0/build> ant -Dvar=-op1\ -op2 
Unknown arg: -op2
but nothing works...

Any idea on how to do this?

In all of these cases, argv[1] will be -Dvar=-op1 -op2
so I'd probably give a double-wrapping trick a try:

ant '-Dvar="-op1 -op2"'

So argv[1] will now be -Dvar="-op1 -op2"

I have no idea if it will work
