使用Ant编译出flex的swc文件

今天新构建了一个Flex Library project项目，但是发现其自动编译的出的swc文件名是无法定义的，自动产生一个跟project name相同的swc文件。这个很不爽，于是决定采用ant来自己编译。
       首先可以参考 http://blog.jodybrewster.net/2008/04/09/installing-ant-in-flex-builder-3/ 这篇文档，在Flex Builder中安装ant enviroment支持。
       构建build.xml和build.properties文件，如下：

###### Flex Properties ##############################
# change this path to your flex sdk directory
# Use "/" in your directory path e.g. C:/FlexSDK/3.0.0
FLEX_HOME=D:/IDE/Adobe/Flex Builder 3/sdks/3.0.0
###### Project Properties ###########################
src-dir=${basedir}/src
swc-file=sample.swc

<project name="Ant build SWC sample" basedir="." default="build SWC">
 <!-- load user configuration properties -->
 <property file="build.properties" />
 <taskdef resource="flexTasks.tasks" classpath="${FLEX_HOME}/ant/lib/flexTasks.jar" />
 <target name="prepareEnv">
    <mkdir dir="${basedir}/swc"/>
 </target>
 <target name="clear" depends="prepareEnv">
    <delete file="${basedir}/swc/${swc-file}"/>
 </target>
 <target name="build SWC" depends="clear"> 
        <fileset dir="${src-dir}" id="src.files">
            <include name="**/**"/>
        </fileset>
        <echo message="${src.files}" />
        <pathconvert
            property="evaFramework_classes"
            pathsep=" "
            dirsep="."
            refid="src.files"
            >
            <map from="\" to="/"/>
            <map from="${src-dir}/" to=""/>
            <mapper>
                <chainedmapper>
                    <globmapper from="*.as" to="*"/>
                </chainedmapper>
            </mapper>
        </pathconvert>
        <echo message="${evaFramework_classes}"/>
     <compc output="${basedir}/swc/${swc-file}" 
     include-classes="${evaFramework_classes}">
     <source-path path-element="${src-dir}" /> 
     </compc>
     
  </target>
</project>

运行ant编辑既可。
