Correct, target/classes is not in the classpath when executing maven on a

I recommend you create a plugin containing the
org.osaf.cosmo.jackrabbit.RepositoryLoader, unless this is generated code.
Normally you don't use the project sources to build the project itself,
but split that out to a reusable plugin.
But if you really must, you can add the target/classes to the classpath
using some jelly magic. I've tried something like this but I can't create
the correct URL[] parameter, but this should give you a start:
<j:new var="file" className="java.io.File">
<j:arg value="target/classes"/>
</j:new>
<j:invoke var="url" method="toURL" on="${file}"/>
<j:invokeStatic var="cthread" method="currentThread"
className="java.lang.Thread"/>
<j:invokeStatic var="urlclassloader"
className="java.net.URLClassLoader"
method="newInstance"
>
<j:arg type="java.net.URL"/> <!-- null, i hope; doesn't work, need [] -->
<j:arg type="java.lang.ClassLoader" value="${cthread.contextClassLoader}"/>
</j:invokeStatic>
<j:invoke method="addURL" on="${urlclassloader}">
<j:arg value="${url}"/>
</j:invoke>
and then use the new classloader 'urlclassloader' to load your class.
Another, better, option is to use define:classLoader
(see
http://jakarta.apache.org/commons/jelly/libs/define/tags.html#define:classLoader
)
but then your class needs to be a Tag.
