Subject [jira] [Commented] (SOLR-3204) solr-commons-csv must not use the org.apache.commons.csv package
Date Wed, 07 Mar 2012 21:28:57 GMT


Benson Margulies commented on SOLR-3204:

So, I hear that you all wish that you had more control over the dependencies that you propagate
when you publish to maven central. Perhaps I could help?

Option 1, which you've already detected, is to use jarjar or shade so that you can publish
your fork of someone else's stuff in your own package namespace fairly painlessly, either
storing it inside some other jar of yours or publishing it under your coordinates.

Option 2 is optional dependencies:

This is a way to force the users of your artifacts to explicitly declare some or all of your
dependencies, rather than getting them automatically. In other words, virality control.

Option 3 is simply to observe that your users can always use 'exclude' to cut off following
some dependency link of yours that doesn't appeal to them.

Does any of this help?

> The solr-commons-csv artifact reused the code from the Apache Commons CSV project but
the package wasn't changed to something else than org.apache.commons.csv in the process. This
creates a compatibility issue as the Apache Commons team works toward an official release
of Commons CSV. It prevents Commons CSV from using its own org.apache.commons.csv package,
or forces the renaming of all the classes to avoid a classpath conflict.
