Could you give some guidance for a newbie like me?
I installed this and now I have under Run->External Tools a new item
MauveBatchRun. If I select that (after following almost everything in
http://developer.classpath.org/mediation/ClasspathHackingWithEclipse) it
seems to configure mauve and then says:
[Console output redirected to file:/home/mark/workspace/mauve/mauve.out]

But there is nothing in that file.

I did commit it so others can play more easily with it though.

Cheers,

Mark

Strangely enough it still doesn't really run for me.

But I did experiment a bit with eclipse and mauve and came up with a
simple SingleTestHarness which can be used with a Runner for quickly
testing a mauve Testlet that you are working on:

2005-12-21  Mark Wielaard  <mark@klomp.org>

        * gnu/testlet/SingleTestHarness.java: New file.

With this you can define a simple runner that uses this class with as
argument ${java_type_name}.

A cool trick here is to do the following:

$ mkdir -p ~/workspace/classpath/install/jre/lib
$ touch ~/workspace/classpath/install/jre/lib/rt.jar

Now you can go to Preferences -> Java -> JRE and add your
workspace/classpath/install as alternative installed jre. Then you can
use this alternative jre for the above runner to get it to test your
mauve Testlets against your the classpath project. Pretty cool :)

Cheers,

Mark

i just checked out Mauve, including this Runner, restarted Eclipse and 
tried it and it (still) works!

i did see the symptoms you're describing when (a) the built VM had 
problems; (b) the VM was not configured properly; e.g. not picking up 
the correct Classpath classes; and/or (c) the environment variables 
--defined in this Runner-- are not being picked up.  in these cases, 
the Mauve scripts would run, but no test class is selected for the 
"runner" script to run them.

the best way to debug why nothing is being written to mauve.out is to 
add some 'echo ' statements in batch_run, choose-classes and runner.  
also, on line 119 of the batch_run script, invert 2 and 1 so you can 
see the stderr output on the Eclipse console.

finally, did you create the symbolic link to mauve-classpath keys file?

Doh...
I saw you also updated the wiki page with those instructions.
http://developer.classpath.org/mediation/ClasspathHackingWithEclipse

It works now for me. Thanks.
