Flex-Ant：mxmlc 不支持“文件”属性

Question

刚刚使用基本的 ant 脚本将我的 Flex 应用程序移至 Ant 上，但我收到了这个愚蠢的错误：mxmlc 不支持“文件”属性。我查看了 docos，看来我的代码是正确的，那么进展如何。

<!-- load previously defined configuration properties file -->
<property file="build.properties" />

<!-- points to our flexTasks.jar we copied to the libs folder to distribute with the project -->
<taskdef resource="flexTasks.tasks" classpath="${basedir}/libs/flexTasks.jar"/> 

<!-- delete and recreate the DEPLOY dir -->
<target name="init">
    <delete dir="${DEPLOY_DIR}" />
    <mkdir dir="${DEPLOY_DIR}" />       
</target>

<!-- Build and output the Main.swf-->
<target name="compile flex project" depends="init">
    <mxmlc file="${SRC_DIR}/DNASupport.mxml"
        actionscript-file-encoding="UTF-8"
        keep-generated-actionscript="false"
        incremental="true"
        optimize="true"
        output="${DEPLOY_DIR}/Main.swf">
        <license product="flexbuilder3" serial-number="137740016118223699076222" />
        <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml" />
        <source-path path-element="${app_root_dir}/src" />
        <source-path path-element="${FLEX_HOME}/frameworks" />
        <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml"/>
        <source-path path-element="${FLEX_HOME}/frameworks"/>
        <compiler.debug>false</compiler.debug>          
    </mxmlc>
</target>

你在使用flex ant任务吗？

这是我的“典型”构建文件的一部分

<taskdef resource="flexTasks.tasks"  />
...
<target name="compile">
  <mxmlc file="Main.mxml" debug="true" output="main.swf">
    <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml" />
    <source-path path-element="${FLEX_HOME}/frameworks" />
    <source-path path-element="${src}" />
  </mxmlc>
</target>

希望这有帮助
