Ant 调用 Shell/CMD 命令

<?xml version="1.0" encoding="utf-8" ?>  
<project name="my_project" basedir=".">  
    <target name="my_make" description="">  
        <exec executable="/bin/sh">  
            <arg line="-c make -f /home/test/ant/Makefile"/>  
        </exec>  
    </target>  
</project>

<?xml version="1.0" encoding="utf-8" ?>  
<project name="my_project" basedir=".">  
    <target name="copy_lib" description="Copy library files from  project1 to project2">
        <exec executable="cmd.exe">
            <arg line="/c &quot;cd ../project1 &amp;&amp; ant copy_to_project2_lib &quot; "/>
    </exec>
    </target>
</project>

<!-- 翻译为命令行就是：cmd.exe /c "cd ../project && ant copy_to_project2_lib"    --> 

意思是直接调用系统控制台，先执行cd命令，再执行ant脚本指定任务，/c 表示执行后续 String 指定的命令，然后停止。
