Difficulty building cactus 1.8.1-S eclipse 3.3 plug-in

Hi,
What I'm trying to do is run JUnit on my Tomcat server in Eclipse so I 
can test applications that use pooled JNDI database connections. That 
seems to mean I need cactus.

I was trying to follow the instructions kindly provided by Petar in the 
mail at
http://www.mail-archive.com/[email protected]/msg07514.html
which almost worked nicely, except the stage where maven tried to get 
the jars for cargo and cactus.build tools.

The files it need were at
http://repository.codehaus.org/org/codehaus/cargo/cargo-core-uberjar/0.9/cargo-core-uberjar-0.9.jar
and
http://repository.codehaus.org/org/codehaus/cargo/cargo-ant/0.9/cargo-ant-0.9.jar

and the instructions in the error made it easy to install them, but 
could one or both of you (Petar and codehaus) make a change to the 
reference to or location of the files such that this just works?

I haven't got cactus built yet (*)-- I can't find something extra to 
just download or check out at jakarta.apache.org/cactus (not 
cactus.apache.org as per the jar). I guess it's something to do with 
https://svn.apache.org/repos/asf/jakarta/cactus/trunk/build-tools/pom.xml  
I'll have to look at the maven docs as I have no idea how it works. I am 
running Debian 4.0 and downloaded maven 2.0.9 into my home directory: I 
run it with ~/apache-maven-2.0.9/bin/mvn

So close to getting it working...

Many thanks,

p.s. I couldn't find a contact email for codehaus, so I just guessed.

(*) I get the error

1) org.apache.cactus:cactus.build.tools:jar:1.8.1-SNAPSHOT

  Try downloading the file manually from the project website.

  Then, install it using the command:
      mvn install:install-file -DgroupId=org.apache.cactus 
-DartifactId=cactus.build.tools -Dversion=1.8.1-SNAPSHOT -Dpackaging=jar 
-Dfile=/path/to/file

  Alternatively, if you host your own repository you can deploy the file 
there:
      mvn deploy:deploy-file -DgroupId=org.apache.cactus 
-DartifactId=cactus.build.tools -Dversion=1.8.1-SNAPSHOT -Dpackaging=jar 
-Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

  Path to dependency:
        1) org.apache.maven.plugins:maven-checkstyle-plugin:maven-plugin:2.1
        2) org.apache.cactus:cactus.build.tools:jar:1.8.1-SNAPSHOT
