How to use YUI Compressor in Ant build script for javascript

Question

I have ANT script which compresses .js files into their own files, but i want to compress all .js files into one .js file.

How to make it work using below ANT script.

<echo message="Compressing Javascript files at location: ${build.root}/resources/js/*.js" />
<java jar="c:/dev/lib/yuicompressor-2.4.7/build/yuicompressor.jar" fork="true">
    <arg value="${build.root}/resources/js/*.js" /> <!-- input path for JS files -->
    <!--<arg value="-v" /> --><!-- Turn on verbose -->
    <arg value="-o" />
    <arg value="'.js$:.js'" />
    <arg value="${build.root}/resources/js/*.js" /> <!-- output path for JS files -->
    <classpath>
        <pathelement location="c:/dev/lib/yuicompressor-2.4.7/build/yuicompressor.jar"/>
    </classpath>
</java>

After a long search I got solution, basically after yui compress i have to do concat on all compressed file.

Use :

    <concat destfile="build/*.js">
        <fileset dir="build/*" includes="*js" />
    </concat>

This doesn't solve the problem. The problem isn't that the OP didn't know how to compress files, it was that they wanted to compress and combine. All this answer does is compress using yui-ant instead of just directly using the yuicompressor.
