Flex ANT tasks can't find my assets

Question

I'm attempting to compile my Flex project with an ANT build script.

One of my MXML components references an external XML data file, like this:

<mx:XML id="treeData" source="assets/data/help.xml" />

When I build the project using Flex Builder, it compiles fine. However, when I try to compile it using ANT, I get the following error:

Error: Problem finding external XML: assets/data/help.xml

How come ANT isn't finding the XML file? Apparently it knows the source path otherwise it would not have found the component to begin with. I added the source path to the target anyway, but it doesn't seem to have made any difference:

<source-path path-element="${SRC}" />

Any ideas?

Answer 1

Added a leading slash to the XML source parameter, and ANT was happy.
