Jenkins Maven - No SNAPSHOT project in the reactor projects list

Two Common Issues With Maven-Release-Plugin

Recently, when working with maven-release-plugin (used in some old, long forgotten codebase) we encountered few issues. This post explains two of them.


SQL Database Diagrams with SchemaSpy, HSQLDB and Groovy

The source code is available at github. Enjoy !

Will Hibernate Switch From Maven to Gradle?

Based on 'Gradle: why?' blog post from Steve Ebersole it seems like Hibernate is moving from Maven2 to Gradle!

Steve's post is really worth reading. He sums up his 2,5 year of Maven experiences and explains why he thinks of its time to move.

That would be just great for Gradle to "capture" such famous project! Go Gradle, go! :)

[Updated 2010-09-24 Hibernate's trunk still uses Maven. I can see two Gradle branches though:]

Gradle talk - Java Camp #3, 10 April 2010, Cracow, Poland

If you happen to be in Cracow (Poland) this Saturday (10 April 2010) and you know polish :) you might be interested in attending the Java Camp #3 conference. See for detailed agenda.

I'm happy to announce that I will give a talk on Gradle at 11 am. I have 1,5 hour to present Gradle and show how it compares to Ant/Maven. My plan is to show a lot of code to present how Gradle can solve real-life scenarios ...and bash Ant/Maven along the way ;).

Hope you will be there !

Do you know this nice tool called Clirr and its Maven plugin ? Well, it is very nice, although it fails miserably in case of some inner class changes. Thus, it doesn't work for some of my projects. :(
