Dependencies from a Multi-module Maven POM

[Matthew Campbell <mt...@gmail.com>]

Hey folks:

    I've just started splicing Ivy into our current build and I'm loving it
so far.  Thanks so much for the great tool.  I've been leaning on some
existing Maven2 repositories to provide dependencies at the moment, and was
wondering if there was a way to grab a multi-module maven project without
explicitly declaring all the modules as dependencies in ivy.xml.  For
instance, the Apache UIMA project has a root project called 'uimaj' that
doesn't contain an artifact in the repository but only the POM referencing a
bunch of modules.  You can view the uimaj POM at:

http://people.apache.org/repo/m2-incubating-repository/org/apache/uima/uimaj/2.2.1-incubating/uimaj-2.2.1-incubating.pom

My dependency in ivy.xml looks like this:

<dependency conf="compile->default" org="org.apache.uima" name="uimaj" rev="
2.2.1-incubating" />

And my ivy-settings has a resolver that looks like the following:

<url name="apache-incubator-maven2" m2compatible="true">
    <artifact pattern="
http://people.apache.org/repo/m2-incubating-repository/[organization]/[module]/[revision]/[module]-[revision].pom"
/>
</url>

I believe it's getting the dependencies correctly, but is not getting any of
the modules listed in the uimaj POM.  I'm forced to define each one as a
separate dependency in ivy.xml, and this scares me a bit since I don't know
if modules will change (added, removed, renamed, etc).  Ideally, I would
only have uimaj as my dependency and the rest would fall into place.  Is
there an accepted way to handle this kind of thing?  Thanks so much for your
time,

There is not yet, and I don't think Maven itself behave like you want
(but I may be wrong). However, we could add a 'modules' configuration
and a dependency for each module in this configuration, so that doing
what you want would be as easy as:
<dependency conf="compile->default,modules" org="org.apache.uima"
name="uimaj" rev="
2.2.1-incubating" />

If you like this, open an improvement issue in JIRA (except if Maven
actually pulls modules as dependencies, in which case this would be a
compatibility bug).
