我正在运行ant来编译Flex应用程序，并且在Windows命令行上运行时，构建会一直失败。我团队中的其他人可以在mac和linux下成功运行相同的构建。
这是命令提示符中显示的错误：

这是compileproject.xml构建文件中的特定目标：
<target name="compile-main" description="Compila la aplicación principal">
<mxmlc allow-source-path-overlap="${compiler.allow_overlap}"
debug="${compiler.debug}"
file="${app.main.mxml}"
fork="${compiler.fork}"
keep-generated-actionscript="${compiler.keep_gen_as}"
link-report="${flex.output.dir}/report.xml"
locale="${compiler.locale}"
maxmemory="256m"
optimize="${compiler.optimize}"
output="${app.main.swf}"
services="${flex.services.dir}/services-config.xml"
>
<!-- Get default compiler options -->
<load-config filename="${FLEX_HOME}/frameworks/flex-config.xml" />
<!-- List of path elements that form the roots of ActionScript class hierarchies -->
<source-path path-element="${FLEX_HOME}/frameworks" />
<!-- Path to the locales -->
<source-path path-element="${flex.resources.dir}/locale/{locale}" />
<!-- List of SWC files or directories that contain SWC files -->
<compiler.library-path dir="${flex.libs.dir}" append="true">
<include name="**/as3-signals-v0.6.swc" />
<include name="**/datavisualization_rb.swc" />
<include name="**/datavisualization.swc" />
<include name="**/GenAocCairngorm.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>
所有标记都设置在相应的build.properties和过滤器.properties文件中（并且，正如我之前所说，它在mac和linux下完美编译）。
Windows版本为7 Ultimate，FLEX_HOME被设置为Flex SDK 3.5（Adobe Flash Builder Burrito附带的3.5.0.12683版本）的环境变量。 $ {compiler.fork}设置为false，以避免SDK和源文件位于不同逻辑驱动器中的问题。
任何线索（根本）都将非常感谢！
