Apache Ant -- use command line argument for target

How can I call a target based on the command line argument? For example, I want to have

ant -Dbits=32 test call <target name="test-32"> and

ant -Dbits=64 test call <target name="test-64">

I tried this:

<target name="test-32">
...
</target>

<target name="test-64">
...
</target>

<target name="test" depends="test-${bits}">

But when I run the script with:

ant -Dbits=32 test

I get the following error:

Target "test-${bits}" does not exist in the project

You could try a trick like

<target name="test.type">
  <property name="run.test${bits}" value="yes"/>
</target>

<target name="test32" if="run.test32">
  ...
</target>

<target name="test64" if="run.test64">
  ...
</target>

<target name="test" depends="test.type, test32, test64"/>

Alternatively, if, as you suggest in the comments, the difference between the 32 and 64 bit cases is just a single property value (a compiler flag) then you could set that property with <condition>, for example

<target name="test">
  <!-- value="..." is the value to use if the condition is true,
       else="..." is the value to use if the condition is false -->
  <condition property="compiler.arch" value="x86_64" else="i386">
    <equals arg1="${bits}" args2="64" />
  </condition>

  <!-- use ${compiler.arch} here -->
</target>

Try the following:

<target name="test">
    <antcall target="test-${bits}"/>
</target>
