How to include a file in ivy.xml?

ant, ivy

Solution

You could create an ivy meta-module, which depends upon all of those common packages, and then have all your other projects resolve the common libraries through transitive dependency:

    <?xml version="1.0"?>
    <ivy-module version="2.0">
        <info organisation="com.example" module="common-libs"/>
          <configurations>
            <conf name="runtime" transitive="true" visibility="public" />
            <conf name="master" transitive="true" visibility="public" />
            <conf name="compile" transitive="true" visibility="public" />
            <conf name="default" transitive="true" visibility="public" extends="master" />
          </configurations>
          <dependencies>
                <dependency org="oracle" name="ojdbc14_g" rev="10.2.0.3"
 conf="compile->compile(*),master(*);runtime->runtime(*);master->master(*)"/>
                <dependency org="tomcat" name="servlet-api" rev="6.0.16" 
 conf="compile->compile(*),master(*);runtime->runtime(*);master->master(*)"/>
                <dependency org="junit" name="junit" rev="4.3"
 conf="compile->compile(*),master(*);runtime->runtime(*);master->master(*)"/>
          </dependencies>
    </ivy-module>

And for a typical project:

<?xml version="1.0"?>
    <ivy-module version="2.0">
    <info organisation="com.example" module="myproject"/>
      <configurations>
        <conf name="runtime" transitive="true" visibility="public" />
        <conf name="master" transitive="true" visibility="public" extends="runtime"/>
        <conf name="compile" transitive="true" visibility="public" />
        <conf name="default" transitive="true" visibility="public" extends="master" />
      </configurations>
      <dependencies>
        <dependency org="com.example" name="common-libs" rev="latest.release" 
          conf="compile->compile(*),master(*);runtime->runtime(*);master->master(*)"/>
      </dependencies>
    </ivy-module>

Here I'm using the traditional configuration naming conventions from the POM->Ivy translations of the Maven resolver, though you could map the configuration names in any way that made sense to you. I tend to use the ivy:install task to copy Maven modules into our Ivy repository, so I use the default ivy.xmls for the most part. If you're using IvyRoundup, you'll primarily want to map the "default" configuration transitively.

Problem

I have a fairly large ivy.xml containing a number of configurations which are the same for a number of projects. I would like to break out this large repetitive section in to a common include file. Somehow I can't find any documentation describing that this can be done. Anyone who has an idea whether this is doable? EDIT: After some further thinking, I think this is not doable on purpose. An Ivy file is meant to be one cohesive unit and should contain no file based references, only references to other ivy modules...
