I see the first problem:

[taskdef] Could not load definitions from resource net/sf/antcontrib/antlib.xml. It could not be found.

This is telling me that you have a task some where in your build.xml file, and that it can no longer find the missing optional Ant jar.

My theory: In your old Ant version under $ANT_HOME/lib, you installed the Ant-Contrib jar. Since this directory is in Ant's $CLASSPATH by default, you didn't have to specify it in your task line, so it looks like this:

I always recommend that you always put these optional task jars into your project. This way, no one has to install these jars in order for them to work since they're already in the project:

• Make a directory /home/my_userid/new_workspace/my_project/antlib/ac, so your project will have a directory antlib/ac in it.
• In this directory, download and install ant-contrib-1.03.jar
• Now change your to include this jar in its classpath.

It should look like this:
