Hi,
junit.jar is in the classpath but removing it (once the test
classes are built) doesn't help, I get the exact same error.
Why are you removing it? It needs to be on the classpath during
compile and while you run the tests. How is junit supposed to run if
it's not even loaded? Also, I believe ant-junit.jar must be on the
classpath *before* you write in the <junit> task (not within the task
itself). Ant can't load the task up if it doesn't have an
implementation for it. I'd recommend sticking both junit.jar and ant-
junit.jar in ANT_HOME/lib because junit will obviously have to load
before ant-junit.
And please don't cc me, I'm already on the list.

I can make it work using the <java> tag to lanuch junit but this
isn't so flexible.
The error and the example ant file that produces it is below. build/
classes/hello contains HelloWorld.class and build/testclasses/hello
contains HelloWorldTest.class.
Hope it's just something trivial I've missed, even if I do get egg
on my face.
Thanks again.

/home/mike/demo/runjunit.xml:19: Could not create task or type of

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 'junit'.
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 META-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
Please neither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.

Please report the specific error printed out.
Also, do you have junit.jar on your classpath as well?
