For some time I've been bugged by a
Netbeans problem that I couldn't find any solution to. When running a unit test from within Netbeans from time to time it happended that the tests just failed. They seemed to be executed in an old state. Running them again didn't help either, it seemed that some parts of the project didn't get recompiled. When executing the tests from a command line Maven build there were never any problems and afterwards the tests could be run again from Netbeans. The problem only occured very infrequently but nevertheless it was really annoying. I started not running the tests from Netbeans at all but only using Maven. That is also not a good solution as you either run all tests or have to edit the command line all the time for running only a single test.
Recently I noticed what caused the problem: Netbeans has its
compile on save feature on for tests. This means it is using its internal incremental compile feature which doesn't seem to work fine at least for some project setups.
You can disable it in the project properties on the Build/Compile node. I haven't seen any problems since disabling it. Saves me a lot of time to run the tests from the IDE again.

Yesterday I attended the
Softwerkskammer Karlsruhe meetup for the first time. Softwerkskammer tries to connect the Software craftmanship community in Germany.
The topic for the evening was simple: More Code. We looked at a lot of samples from a real project and discussed what's wrong with them and what could be done better. There were a lot of different opinions but that's a good thing as I got to question some habits I have when programming.
This has been the first time I've been to a meeting where there is a lively discussion like this. The conferences and
user groups I attend mostly have classic talks with one speaker and far less audience participation. Talking about code is a really good way to learn and this won't be the last time I attended a meetup. Thanks to the organizers.

Sometimes it's comfortable to not be an absolute expert in a certain technology. This makes it really easy to learn new stuff, e.g. by profane methods like reading a book. Even if you are a Spring expert it is still likely that you will take something from the latest edition of Spring in Action by Craig Walls as it covers a wide range of topics. I haven't read one of the predecessors but people told me that those are even better.
