Thumbs up ANT task macrodef - Error message: Unknown attribute
Hello,

I'm trying to run the following ant file:
<project name="test" basedir="." default="test">

Code:
<macrodef name="testing">
<attribute name="v" default="NOT SET"/>
   <sequential>
      <echo>v is @{v}</echo>
   </sequential>
</macrodef>

<target name="test">
    <echo>start test</echo>		
    <testing v="This is v">
    </testing>
    <echo>end test</echo>
</target>
</project>


When running the task from the eclips, using ant plug in, the task is working succefully.

Now I wrote a jave code, running under Jboss server, that run the task.
And i'm having a problem with the MacroDef task (other tasks are working).

I'm getting the error message:
Code:
Unknown attribute [v]
	at org.apache.tools.ant.taskdefs.MacroInstance.execute(MacroInstance.java:382)

	at org.apache.tools.ant.Project.executeTarget(Project.java:1298)


I'm guessing it sonething to do with diffrent Jars, but i couldn't find the diffrents.

Thanks,

It probably does. Ensure that you are using current versions of Ant in both environments.

I don't know how to be more specific than "ensure you are using current versions of Ant in both environments." That sounds pretty specific to me. *shrugs*

The MacroDef task has been available since Ant 1.6, but is still apparently in beta. You can see this in the Ant documentation.

ant.jar

Apperently there was no problem with the jars.

The problem was in the Java code parsing the Ant file.
I used the code
Code:
final ProjectHelper helper = new ProjectHelperImpl();
helper.parse(ant, new File("D:\\testAnt\\test2.xml"));


And I should have used:
Code:
ProjectHelper.configureProject(ant, new File("D:\\testAnt\\test2.xml));


Hopefully this will help to someone else.
