Subject Ivy Maven 2 Compatibility
Date Wed, 12 Mar 2008 20:43:48 GMT

As you may have noticed on the ivy user list I've just setup a small
web site for searching Maven 2 repository:

To implement this I've used Ivy Pom parser to parse poms from the
maven 2 repository, to extract some basic information like the
description and home page. This is a bit overkill for what I do in
javarepo, but the nice side effect is that I now have an error log
with all modules in current maven 2 repo for which Ivy is failing at
parse time. The error log is here:

As you can see a lot of errors are xml errors (use of undeclared
entity, unclosed tags, content not allowed in prolog, ...). There's
also quite a lot of poms in which we don't find the module name (I
haven't checked if this is our fault yet). Note that in my parsing I
haven't setup Ivy correctly, so Ivy was not able to find parent or
relocated modules, which may cause errors in the log we wouldn't have
in reality.

The good news is that we only have about 200 errors for the 28k+ poms
available in maven repo. This is not too bad, even though it doesn't
tell how different the dependency resolution itself would be.
