[Ant]Iterate over Tokens

[Rafael Afonso]

Hello:

In a ant buildfile, I have a property with strings separated with commas:

  
<property name="classes" value="Classe1,Classe2,Classe3"/>

Now I want iterate over these tokens to execute some task. It would be like use String.split() Or use <forToken> JSTL tag. Exemple:

  
<forToken items="${classes}" var="classe">
    <rmic base="bin" classname="${classe}"/>
</forToken>

But I did nothing about this in Web. Comeone knows how to do this?

Thank,

Rafael,
You can't do it in pure Ant. Instead, you can use an embedded scripting language like BSF (very similar to Java) to do the split. Then invoke a real Ant task with each of the classes.

Yes, you can, <foreach> from ant-contrib is exactly created for this comma seperated list.

foreach is a great task!

Good to know. Gotta write that one down!

Hello:

Thanks to all. I have did this using javascript:

  
   <script description="Run rimc to create RMI stubs" language="javascript" > <![CDATA[
            importClass(java.io.File);   
            // "myproject" is the project name defined in "project"'s attribute "name" 
            var rmic = myproject.createTask("rmic");
            rmic.setStubVersion("1.2");
            rmic.setBase(new File(pegasus2NG.getProperty("build.dir")));  // defined in property file
            // "mytarget" is the target name defined in "name" attribute of "target"
            mytarget.addTask(rmic);
            var classes = myproject.getProperty("rmi.classes").split(","); // defined in property file
            for(var i = 0; i < classes.length; i ++) {
                rmic.setClassname(classes[i]);
                rmic.execute();   
            }   
            ]]>
        </script>    

I did not know about ant-contrib. I will look at this.

thanks
