利用Ant自动编译Flex程序

ant是一个基于JAVA的自动化脚本引擎，脚本格式为XML。除了做JAVA编译相关任务外，ANT还可以通过插件实现很多应用的调用。

平时我们在编译Flex文件时都是使用的FlexBuilder提供的编译功能,也可以实现自动编译的功能,但如果项目一大,涉及到一些公共组件的调用比较多时,这种编译就不是很方便了.

在习惯了利用ant自动化编译部署Java应用程序的方便功能以后,自然想到也要利用ant的脚本功能进行Flex的自动编译,以下就是我写的关于编译Flex的build.xml文件(附件中有实例工程压缩文件),实现了自动编译与生成API文档的功能:

<?xml version="1.0"?>
<project name="flex_examples" basedir="../" default="compile_modified">

	<property file="./build/build.properties" />

	<!--
		Have you edit the properties file to make sure the paths are right on your system?
	-->
	<target name="properties">
		<fail unless="asdoc.exe">The "asdoc.exe" property must be set in ${build.dir}/build.properties.</fail>
		<fail unless="compc.exe">The "compc.exe" property must be set in ${build.dir}/build.properties.</fail>
		<fail unless="mxmlc.exe">The "mxmlc.exe" property must be set in ${build.dir}/build.properties.</fail>
	</target>

	<!-- 
		Extension for ANT to allow for tasks like "for" and "propertyregex"
	-->
	<taskdef resource="net/sf/antcontrib/antlib.xml">
		<classpath>
			<pathelement location="libs/ant/ant-contrib.jar" />
		</classpath>
	</taskdef>

	<!--
		Generate the main applications using the library
	-->
	<target name="compile_modified" depends="properties">
		<!-- 
			Loop over all of the Sample applications in the mains directory,
			compile them, and place the resulting .swf next to the application
			.mxml file.
		-->
		<for param="file">
			<!-- Find the sample applications -->
			<fileset dir="${src.dir}">
				<!-- 
					The modified selector will only select files that have been
					modified since the mains target was last run. This means we
					can update a single main, then run the mains target and
					only the updated main will get recompiled.
				-->
				<modified/>
				<include name="**/*${application.name.flag}.mxml" />
				<!-- 
					For only building specific mains, comment out
					the line above, and uncomment the line below and modify
					as appropriate.
				-->
				<!--<include name="**/HorizontalAxisDataSelector_Sample.mxml" />-->
			</fileset>

			<sequential>
				<propertyregex property="mainApplicationName" override="yes" input="@{file}"
										regexp=".*\${file.separator}(.*)${application.name.flag}.mxml" replace="\1" />
				<propertyregex property="mainFolderName" override="yes" input="@{file}"
										regexp="(.*)\${file.separator}(.*)${application.name.flag}.mxml" replace="\1" />

				<exec executable="${mxmlc.exe}" dir="${basedir}">
					<arg line="'@{file}'" />
					<arg line="-o '${mainFolderName}/${mainApplicationName}${application.name.flag}.swf'" />

					<arg line="-l '${lib.dir}'" />
					<arg line="-l '${flexsdk.lib.dir}'" />
					<arg line="-sp '${src.dir}'" />

					<arg line="-optimize" />

					<arg line="-locale ${flexsdk.locale}" />
					<arg line="-l '${flexsdk.locale.dir}'" />
				</exec>
			</sequential>
		</for>

	</target>

	<!--
		Generate ASDoc output for the library
	-->
	<target name="docs" depends="properties">
		<!-- Clean out the contents of the doc directory, without deleting "docs" -->

		<delete includeemptydirs="true">
			<fileset dir="${docs.dir}" includes="**/*" />
		</delete>

		<exec executable="${asdoc.exe}" spawn="no">
			<!-- Place the documentation in the "docs" directory -->
			<arg line="-o '${docs.dir}'" />

			<!-- Specify the main source path as "src" -->
			<arg line="-sp '${src.dir}'" />

			<!-- Document all of the classes in the "src" tree -->
			<arg line="-ds '${src.dir}' " />
