Maven is often put in a bad light because of bad metadata. So if the
metadata could be improved Maven would be perceived as being better.
With this in mind, I'd like to start work on a new component.
Which metadata are you referring to? I think the "bad light" often
comes from POMs, but there is also a policy of not updating them in a
release repo. However, we might be able to catch it in advance of
syncing in a repo which would be helpful. Then there are the maven-
metadata.xml files which are basically just a nuisance when wrong but
easily and automatically fixed.
However, I think it sounds like you're talking about repo metadata -
is that right?
A. Library to traverse a repository. Candidates:
- Wagon
- HttpClient
I don't think traversing a remote repository is a good idea - I'd say
stick to running it on the local filesystem.
B. Library to read and parse metadata.xml files. Later on we would
also
need to write metadata.xml files. Candidates:
- Do we have code for this somewhere?
Yes, in maven 2.0.x there is a metadata library (I think it's been
merged somewhere into maven-artifact 3.0).
Archiva has some separate libraries for manipulating these as well
that might be more accessible in the short term (in a future version
it may use maven-artifact 3.0 though).
I think you are already familiar with the code that loads POMs through
the work you did on the converters?
I will put this up on the wiki in a bit. But first I wanted to get
some
feedback on the proposal as such, and also comments and suggestions on
the choice of tools.
It's a good thing to have in both regards. However, I'll note that a
running Archiva server would already do all of this for you - it can
identify POMs that are mismatched with the repository and present them
in a report, as well as locate bad metadata files (and can autocorrect
them). eg: http://maven.apache.org/archiva/docs/1.0/tour/reports.html
It may not be as quick a win for you, but I would really like to see a
CLI produced for Archiva to put on the front of those to do what you
are looking for on demand and produce static reports. WDYT?
Cheers,
Brett
