optional depends for targets

Hi,

Is it possible for a target to optionally depend on another target? For example consider 

target A has an optional dependency on target B 
target C depends on target A

When the build is invoked with target C then only targets A and C should get executed in the order A,C. However if the build is invoked with targets C,B,A then the targets should be executed in the order B, A, C.

Thanks
Vimil

I Use the <if> from antcontrib to achieve this.

This is how I deal with that: simply set up two (I call them) synthetic targets. One depends on A and C, the other on B, A, and C. Then call one or the other of them. They only need the depends:

<target name="buildForProduction" depends="B,A,C"/>
