Problem: failed to create task or type for Cause: The name is undefined.

[zabin shariff]

Hi there

I was trying to iterate a list using for tag in my build.xml. But getting this error:

D:\Workspaces\myWorkspace\POC\build.xml:15: Problem: failed to create task or type for
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

My build .xml looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<project name="POC" default="test" basedir=".">
    <description>
        simple example build file
    </description>
  
  <target name="test" >
   	<echo message="test"/>
  	<for list="a,b,c,d" delim="," param="x">
  		<sequential>
  	   		<echo message="${x}" />
  		</sequential>
  	</for>
  </target>
</project>

Can anybody tell where I am doing wrong

FYI: I am using eclipse 3.5 which has ANT3.7

Is the for task a standard task in ANT?

[David Newton]

The "for" task is in ant-contrib. Have you installed it correctly? Have you provided a taskdef for it that you're not showing here?

Hi

It seems I have not provided a typedef for "for" . I corrected myself and changed my code to this:

<ac:for list="a,b,c,d" delim="," param="x" xmlns:ac="antlib:net.sf.antcontrib">
  		<ac:sequential>
  	   		<echo message="${x}" />
  		</ac:sequential>
  	</ac:for>

I got this error:

This appears to be an antlib declaration. 
Action: Check that the implementing library exists in one of:
        -D:\eclipse\plugins\org.apache.ant_1.7.1.v20090120-1145\lib
        -C:\Documents and Settings\java02\.ant\lib
        -a directory added on the command line with the -lib argument

So I checked the plugins library in eclipse folder and found that there is no ant-lib there. So I downloaded one and copied it to the lib folder of the ant plugin. But still I am getting the same error. Do I need to set the path somewhere. I am using Eclipse Galileo 3.5 which has ANT as plugin so i haven't downloaded ANT and configured it in my system manually.
Any suggestions

Hi there
I got the solution
I imported the jar(ant-contrib-1.0b3 which I have downloaded and kept in eclipse/plugins/org.apache.ant_1.7.1.v20090120-1145/lib) in Eclipse, by Windows--?Preferences-->Ant-->Runtime--->Add External Jars in Ant Home Entries.
Now my build.xml is working fine:
Here is my snippet:

<?xml version="1.0" encoding="UTF-8"?>
<project name="POC" default="test" basedir="." xmlns:ac="antlib:net.sf.antcontrib">
    <description>
        simple example build file
    </description>
  <target name="test" >
   	<echo message="test"/>
  	 
  	<echo message="The first five letters of the alphabet are:"/>
  	<ac:for list="a,b,c,d,e" param="letter">
  	  <sequential>
  	    <echo>Letter @{letter}</echo>
  	  </sequential>
  	</ac:for>

  </target>
</project>

Glad to hear you got it working!

One more addition - sometimes ant is thick about finding its lib directory, so it doesn't look like you added the ant-contrib-jar even when you did.
One way to check that is to add a -lib <hard path to your ant lib directory> to the end of your ant command line & see if this problem goes away.
If so, ant is looking in the wrong lib directory on your system.
