Hello,

I updated my svn clone of Avro after quite a while and noticed that
the Java build has moved from Ant to Maven. I'm was not very familiar
with maven based projects yet, but I got some reading done and am able
to use it now. But I have a remaining question that I was not able to
solve:

How do I ask it to generate Eclipse project files? I liked the
'eclipse' or 'eclipse-files' target in the earlier Ant-based build
system of Avro which easily generated Eclipse project files. But when
I try "maven install; maven eclipse:eclipse" it fails for the tools
package (in the eclipse part, the install goes fine). I do not have
enough experience with Maven to know if it is a fault I'm doing or if
it is a fault with the build files related to maven. Any help with
creating eclipse project files for Avro's Java sub-project?

Simply mvn eclipse:eclipse. That being said..

..it's not your fault, merely a bug in the particular version of the
eclipse plugin declared in the pom.

I posted the following to the dev list a few days ago:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg02145.html

So a quick fix is to change the declared version of the plugin back to
2.7. Whether this behaviour is a "bug"/"oddity" in the avro build
(referencing out-of-module resources) or the plugin is debatable, see the
mentioned JIRA for more.

hope this helps.

That did help a lot, thank you! I should've searched my archives for
typical keywords before mailing, so I'll also add an apology for that
too :-)

Thank you again Holger!

See the documentation on the wiki:
https://cwiki.apache.org/confluence/display/AVRO/Build+Documentation

The maven eclipse plugin is one option, the other is the eclipse M2Eclipse
plugin.  Don't mix the two.

The project was migrated and tested with M2Eclipse.  The instructions for
importing projects with it are in the link above, but I'll repeat them
here:

Building Instructions: EclipseUse Eclipse 3.6 Helios
<http://www.eclipse.org/downloads/>
Use the m2Eclipse plugin
<http://m2eclipse.sonatype.org/installing-m2eclipse.html>.

 
* Load the projects into the workspace using the "Import ..." dialog, and
select "Existing Maven Projects"
 
* Select the lang/java directory, and it should show all projects
including the parent.  Import all of these.
 
* After the load and first build, it will not completely compile.  To
 fix it up to compile, select all of the projects and right-click.
Select Maven > Update Project Configuration.
For those that use the maven eclipse plugin, It would be great if someone
documented the wiki page with instructions on using it with Avro.
