Hope anybody can help me , I am trying to use the eclipse.refreshLocal task in an ant build.xml. I am running ant from command line and eclipse in headless mode. The ant build.xml first unzips a workspace and then I call refreshLocal to refresh the projects. As soon as ant tries to run that task it gives me (see below) :

Ant could not find the task or a class this task relies upon.

This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'eclipse.refreshLocal'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and the JAR file and/or libraries
implementing the functionality were not found at the time you
yourself built your installation of Ant from the Ant sources.
Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the
task and make sure it contains more than merely a ****-INF/MANIFEST.MF.
If all it contains is the manifest, then rebuild Ant with the needed
libraries present in ${ant.home}/lib/optional/ , or alternatively,
download a pre-built release version from apache.org
- The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
and needs to be declared using <taskdef>.
- You are attempting to use a task defined using
<presetdef> or <macrodef> but have spelt wrong or not
defined it at the point of use

Remember that for JAR files to be visible to Ant tasks implemented
in ANT_HOME/lib, the files must be in the same directory or on the
classpath

If I am running ant from eclipse I can set it to run the Ant task in same VM, but how can I make it do that in the headless mode ? I need to get this working urgently.
Btw the jar file with the eclipse ant task has been put in the ANT_HOME/lib dir.
(PS running in Linux)
