A module defines one or more configurations, which will be used to
meet different needs. For example, the logging framework slf4j defines
a "core" configuration, which includes only the API jar. It then has a
configs for each implementation choice a user might want, "log4j",
"jul", "jcl", etc.
That actually makes sense. :-) So it is a qualifier, though up by the
developer. Is there some central place where one can find these
qualifiers? Like the pom.xml in the Maven repositories?
I'm not sure that the Maven poms usually specify a scope. Some may,
but many may not. For high-quality Ivy modules, I recommend Ivy Roundup:
http://code.google.com/p/ivyroundup/
So what would be the appropriate way to split-up the set. As said: I
want to split between between what is required at compiletime, test and
runtime. The leading example would be that junit should not be present
in lib but lib-test.
I typically have some configurations like the following:
<conf name="default" transitive="true" visibility="public" />
<conf name="runtime" transitive="true" visibility="public" />
<conf name="compile" extends="deploy" transitive="true"
visibility="private" />
<conf name="test" extends="deploy" transitive="true"
visibility="private" />
<conf name="sources" transitive="true" visibility="public" />
<conf name="javadocs" transitive="true" visibility="public" />
The public configurations are there for me to define publications
which will be visible to other modules. The private ones are just for
specifying dependencies during my different phases of
compile/test/run. For compile and test, I generally need everything
required by runtime (so I extend that config), plus some extra
libraries (like junit for testing or servlet-api for compilation).
Appearantly I did something wrong. Running "ivy:retrieve" now downloads
94 jars. Ok. However, if I I now want to split up like this:
<ivy:retrieve conf="runtime" pattern="lib/[artifact]-[revision].[ext]"/>
<ivy:retrieve conf="test" pattern="lib-test/[artifact]-[revision].[ext]"/>
<ivy:retrieve conf="build" pattern="lib-ext/[artifact]-[revision].[ext]"/>
Then I get an error
/BUILD FAILED
C:\Documents and Settings\User\My
Documents\kpprofiler2\components\service\build.xml:39: impossible to ivy
retrieve: java.lang.RuntimeException: problem during
retrieve of nl.knowledgeplaza#kpprofiler-service:

org.codehaus.enunciate#enunciate-rt;1.10 are ret

OK, many projects have source and jar artifacts with the same name, so
you really want to either set a retrieve pattern which includes the
type of the artifact for disambiguation. If you cannot do this, you'll
need to specify an exclusion rule for your dependencies to only
include type jar. Here are examples of both:
<ivy:retrieve
pattern="${ivy.lib.dir}/[type]/[artifact]-[revision].[ext]"
haltonfailure="true" conf="build" sync="true"/>
<dependencies>
<exclude type="source"/>
</dependencies>
