利用Ant将flex中的mxml文件编译成swf文件的三种方法

今天学习并试验了三种利用Ant将mxml编译成swf的方法

使用Ant编译mxml的几种方法：

1.可执行版的exec

<?xmlversion="1.0"?>

<projectname="FlexAntTasksBuildScript"default="compileMain">

<!--propertyfile="build.properties"/-->

<propertyname="dir.src"value="src"/>

<propertyname="dir.build"value="build"/>

<propertyname="FLEX_HOME"value="D:/ProgramFiles/Adobe/FlexBuilder3Plug-in/sdks/3.2.0"/>

<targetname="init">

<deletedir="${dir.build}"/>

<mkdirdir="${dir.build}"/>

</target>

<targetname="compileMain"depends="init"description="Compilesthemainapplicationfiles.">

<echomessage="Compiling${dir.build}/main.swf..."/>

<execexecutable="${FLEX_HOME}/bin/mxmlc.exe"spawn="false">

<argline="${dir.src}/main.mxml"/>

<argline="-output${dir.build}/main.swf"/>

</exec></target>

</project>

2.Java版

<?xmlversion="1.0"?>

<projectname="FlexAntTasksBuildScript"default="compileMain">

<!--propertyfile="build.properties"/-->

<propertyname="dir.src"value="src"/>

<propertyname="dir.build"value="build"/>

<propertyname="FLEX_HOME"value="D:/ProgramFiles/Adobe/FlexBuilder3Plug-in/sdks/3.2.0"/>

<targetname="init">

<deletedir="${dir.build}"/>

<mkdirdir="${dir.build}"/>

</target>

<targetname="compileMain"depends="init"description="Compilesthemainapplicationfiles.">

<echomessage="Compiling${dir.build}/main.swf..."/>

<javajar="${FLEX_HOME}/lib/mxmlc.jar"fork="true"failonerror="true">

<argvalue="+flexlib=${FLEX_HOME}/frameworks"/>

<argvalue="-file-specs=${dir.src}/main.mxml"/>

<argvalue="-output=${dir.build}/main.swf"/>

</java></target>

</project>

3.使用Flex3SDK中的mxmlc任务

为了能访问所要build文件中的信息，首先添加一个任务定义

<?xmlversion="1.0"?>

<projectname="FlexAntTasksBuildScript"default="compileMain">

<!--propertyfile="build.properties"/-->

<propertyname="dir.src"value="src"/>

<propertyname="dir.build"value="build"/>

<propertyname="FLEX_HOME"value="D:/ProgramFiles/Adobe/FlexBuilder3Plug-in/sdks/3.2.0"/>

<taskdefresource="flexTasks.tasks"classpath="${FLEX_HOME}/ant/lib/flexTasks.jar"/>

<targetname="init">

<deletedir="${dir.build}"/>

<mkdirdir="${dir.build}"/>

</target>

<targetname="compileMain"depends="init"description="Compilesthemainapplicationfiles.">

<echomessage="Compiling${dir.build}/main.swf..."/>

<mxmlcfile="${dir.src}/main.mxml"output="${dir.build}/main.swf">

<source-pathpath-element="${dir.src}"/>

</mxmlc></target>

</project>

以上swf的output文件目录可以不指定，如不指定，默认为mxml所在目录
