To invoke the tags body from inside a dynamic tag use <define:invokeBody/>
If you wish to capture the output of the body as a variable and then pass it
into some other tag/bean/method then try something like this (warning - this
is untested, am just typing it straight into an email client which doesn't
yet have Jelly support :)
<define:tag name="exec">
<!-- allow either command attribute or use body of exec tag -->
<j:if test="${empty(command)}">
<j:set var="command"><define:invokeBody/></j:set>
</j:if>
<exec dir="." executable="${maven.ssh.executable}">
<arg line="${maven.repo.central} -l ${maven.username}
'${command}'"/>
</exec>
</define:tag>
