I'm running ant to compile a Flex application, and the build keeps failing when running it on a windows command line. Other people in my team can successfully run the very same build under mac and linux.
This is the error shown in the command prompt:
compile-main:

This is the particular target in the compileproject.xml build file:

<!-- List of path elements that form the roots of ActionScript class hierarchies -->

<!-- Path to the locales -->

<!-- List of SWC files or directories that contain SWC files -->
<compiler.library-path dir="${flex.libs.dir}" append="true">

<include name="**/datavisualization_rb.swc" />
<include name="**/datavisualization.swc" />

<include name="**/GenAocLib.swc" />
</compiler.library-path>
<compiler.library-path dir="${flex.src.dir}/assets" append="true">
<include name="**/*.swc" />
</compiler.library-path>
</mxmlc>
</target>
All tokens are set in corresponding build.properties and filter .properties files (and, as I said before, it compiles perfectly under mac and linux).
The windows version is 7 Ultimate, FLEX_HOME is set as an environment variable to the Flex SDK 3.5 (the 3.5.0.12683 build that comes with Adobe Flash Builder Burrito). ${compiler.fork} is set to false, to avoid an issue with the SDK and the source files being in different logic drives.
Any clues (at all) will be greatly appreciated!
Maybe it's a problem of the "Burrito Preview"? You could file this as a bug at http://bugs.adobe.com.
