Hi All,
Sorry I forgot to send this initially to this list...
My comments are interwoven...

Slightly different implementation but same result.
You would put the connection strings in $HOME/.m2/settings.xml
http://maven.apache.org/maven-settings/settings.html
and place your various properties in (pseudo xpath)
/settings/profiles/profile/id="foo"/name="cayenne.adapter"
/settings/profiles/profile/id="foo"/
value="org.objectstyle.cayenne.dba.mysql.MySQLAdapter"
/settings/profiles/profile/id="foo"/name="jdbc.username"
/settings/profiles/profile/id="foo"/value="someuser"
...
/settings/profiles/profile/id="bar"/name="cayenne.adapter"
/settings/profiles/profile/id="bar"/
value="org.objectstyle.cayenne.dba.oracle.OracleAdapter"
/settings/profiles/profile/id="bar"/name="jdbc.username"
/settings/profiles/profile/id="bar"/value="otheruser"
...
then you can invoke the 'foo' connection via
$mvn -P foo
With this the value of 'cayenne.adapter' would be
'o.o.c.d.mysql.MySQLAdapter'
$mvn -P bar
would yield 'cayenne.adapter' would be 'o.o.c.d.mysql.OracleAdapter'
I'm not sure how to pass in different filters for the test classes to
run but I expect that it would be possible with the same setup via
the settings.xml file under a different profile. Then you can coma
delimt the profiles to activate like this;
$mvn -P bar,groovyTests

Yes MacBook Pro! that will solve everything! I'm waiting for the 17"
though...
Now on to the real issue... This is really a job well suited to
TestNG, not JUnit and Ant file filters but that is a story for
another day. I've not done this sort of thing with maven but I'd
assume that we would set up a filter property in a profile and use
that to filter out all other tests.

Maven makes a great developer site and a moderately good user site.
The maven site (http://maven.apache.org/) is a good representation of
what is easy with maven. Other customizations are possible but not as
easy. I think doing a reduex of the Cayenne site on the easy side of
customization. I'll have a go at it some time soon and see what I can
come up with :-)

2 ways:
1) $mvn eclipse:eclipse and then modify a 'build variable' in eclipse
by setting M2_REPO (it typically is $HOME/.m2/repository)
cool thing about this that mvn idea:idea and mvn netbeans:netbeans
etc all work as well so developers can use any ide they want (I'm not
sure of all the supported ones but eclpse, idea and netbeans have
support).
2) use the maven 2 plugin for eclipse, its very cool, works a lot
like ant and makes your life easy

There is a plugin that allows you to invoke ant from your maven2 build.
http://maven.apache.org/plugins/maven-antrun-plugin/run-mojo.html
I've not used it but Matt Raible has and I can always go make him
explain it :-)

Ok I need to get cracking!
