Question

I have to create a single command to create multiple(dev|qa|uat) war/ear.
Something like :

ant -f build.xml -Denv=dev|qa|uat -propertyfile= devProp|qaProp|uatProp 
  -Dstage.dir=devdir|qadir|uatdir

I already have different properties file, different staging, deploying target for each environment. I also have different .cmd files to build each of them separately.

What I am stuck at is: How do I build them all in one go?

You can use the <subant /> instruction in your target.

Write down a new ant script (namely master.xml), assuming that your original build is in script build.xml, you can have something like:

<target name="build-all">
   <subant target="build-prod">
     <fileset dir="." includes="build.xml"/>
     <propertyset ......../> <!-- properties for the prod build -->
   </subant>
   <subant target="build-dev">
     <fileset dir="." includes="build.xml"/>
     <propertyset ......../> <!-- properties for the dev build -->
   </subant>
</target>
