QuickStart example just doesn't work
Am I just broken? Nothing could be easier to download and set up, but
walking the QuickStart
(http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html),
I find the example simply doesn't work.

The class is indeed there as my tree command shows, but Java can't find
it. This problem would not happen in Eclipse as long as the code is
there, but as it's Maven that's going to do the build eventually, it
won't work. Or, maybe JDK 6 is broken for Maven's use.

Looks like you missed this section:
Build the Project
mvn package
The command line will print out various actions, and end with the
following:

Unlike the first command executed (archetype:create ) you may notice the
second is simply a single word - package . Rather than a goal, this is a
phase . A phase is a step in the build lifecycle , which is an ordered
sequence of phases. When a phase is given, Maven will execute every
phase in the sequence up to and including the one defined. For example,
if we execute the compile phase, the phases that actually get executed
are:
1. validate
2. generate-sources
3. process-sources
4. generate-resources
5. process-resources
6. compile

You're absolutely right. Somehow I missed the mvn package command in the
5-minute quick start stuff and I have no excuse for that.
Wow, this stuff works really well now. Thanks to both of you for this
answer.

Try 'mvn install' before you try to execute it. At least, I don't see
where you ever compiled the code and created the jar...
Creating an archetype with Maven doesn't mean it's watching to see
when things need to be compiled. As you pointed out, that's what IDEs
do for you.
