My arguments node looks like:
<arguments>-clobber -map:v3 app\script.min.js.map</arguments>
My min file is: script.min.js and the output node is: <output path="app\script.min.js">
I also tried the path with quotes in it but it didn't make a difference. Not sure if this is a bug or whether I'm configuring my flags incorrectly.
found the issue. i was using an argument when i was supposed to use the "symbolMap" child node under the "output" node, like so:
<symbolMap name="v3" path="app\script.min.js.map" />
