Unfortunately I have not much time to investigate into building a better Java package management system I talked (or better ranted) about yesterday. But sometimes walking rather slow means also avoiding walking too fast. There is more time for looking around. In the past I analyzed different projects and code bases, e.g. Maven, Raven and Buildr or Portage, but I didn't found a best match. Of course I'm seeing much potentials in Portage, but it's written in Python and this could be a no go for some developers.

Today I discovered the Kepler Project. Carlos Sanchez blogged about the Eclipse Summit 2007 and the need for a plugin/bundle repository for Eclipse. As he stated, one wish or idea is to use a Maven compatible repository. Kepler tries exactly that, beeing a standard package repository while preserving compatibility to other package formats. I will have to keep an eye on this project.

The fourth and last talk on the second Haskell in Leipzig Meeting was hold by Leif Frenzel (Karlsruhe). He spoke about Cohatoe, an Eclipse Plugin to support Haskell-written Eclipse Plugins. This was the official release of an already usable Cohatoe Eclipse Plugin. The talk is in German.

Don't miss the "Stolperstein" when watching this video.

you can find the slides of this talk on Leif's homepage.

Leif Frenzel released Cohatoe 0.5, an Eclipse plugin, which allows you to write Eclipse plugins directly in Haskell. Leif wrote, that this version will have almost all planned features of the 1.0 release. This version has now an extension wizard and is able to handle running extentions from Haskell source code. It is the version Leif presented a the Haskell in Leipzig 2 meeting. Cohatoe switched its repository to the EclipseFP webspace and newer releases will only be found there.

The yesterdays second Haskell in Leipzig Meeting (HaL) was just great. As last time we reached the limits of our conference room we decided to arrange the next Haskell meeting at Victor Jara. This was the absolutely right decision. We had a pleasant ambience in the cellar of the old Leipziger Felsenkeller. The team of Victor Jara prepared us a really great conference atmosphere - so, many thanks and compliments to you, Lütti.

The first talk was hold by Johan Jeuring (Univ. Utrecht) who gave an overview over Generic Programming in Haskell. He presented a field of his actual work: Finding criteria for a standardized Generic Programming library for Haskell. At the end of this talk he gave yet another hint for this year's functional programming contest.

Are you interestred in Functional Programming (FP)?
Maybe you are using Haskell already.
Or you are a Java developer and made your first functional steps with Scala and now you feel like learning more real FP languages and heared that Haskell is the best one.

This is your chance...

• To meet other Haskell'er
• To hear good talks about Haskell and Functional Programming
• To be guest of a release party of CoHatoE (Contributing Haskell to Eclipse)
• To visit Leipzig, Germany
• To have a functional breakfast

Then come to the Second Haskell in Leipzig (HaL2) meeting on Tuesday, July 10, 2007.

Here is an short summary of the planned schedule:

A while ago we switched for a couple of projects from JUnit to TestNG. Everything went fine with maven and Eclipse, but yesterday I recognized while running maven clean test that the tests where found but not executed. I got many lines like these:


Running de.ibacg.XXX.dao.jpa.test.UserDaoAndRoleDaoTest
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.445 sec
Running de.ibacg.XXX.dao.jpa.test.StatusProtocolEntryDaoTest
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.007 sec
Running de.ibacg.XXX.services.provider.test.MasterDaoProviderTest
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.688 sec
...

Results :
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0


Very strange, as all these tests contain at least two test methods and are annotated with @Test on method- or class-level.
