Solution 1

There are two ways to achieve this:

You can do this with antcall.
Since ant 1.6, you can use macros.

Solution 2

What you want is macro-def.

For a really good guide to writing Ant macros check out this presentation.

!!! Netbeans 6.7 RELEASED !!! C is far better and easier than Java! Why? It is easier to use void pointers and to do pointer arithmetic, than explaining the basic concepts of OOP to a C programmer. Joke of the century: PHP is good, because it works... "PHP programming" is an oxymoron. There is no PHP programming. There is only PHP scriptkidding. There are two types of people who use PHP: - those who don't know other languages, - and those who HAVE TO use it Java is to JavaScript what Car is to Carpet. The LHC is the wrong answer to the technological singularity.

Can I write an ant task which takes parameters when being executed from another ant task?

What I try to achieve in general, is re-using existing tasks with different parameters.

What I don't know is:
- is there something such a sub-task in ant?
- can it take parameters?
- how and where such sub-task is specified?
Concept of what I need to achieve:

Sub Ant task, which takes parameters param1 and param2:
```
<someAntCommand att="$param1"/>
<someOtherAntCommand att="$param2"/>
```
Main Ant task, which executes the sub task:
```
<doSomethingToExecSubTask somePointerToTaskOrFile="...">
    <param name="param1"> hello </param>
    <param name="param2"> world </param>
</doSomethingToExecSubTask>

<doSomethingToExecSubTask somePointerToTaskOrFile="...">
    <param name="param1"> hello </param>
    <param name="param2"> universe </param>
</doSomethingToExecSubTask>
```
