As the SonarQube guys removed that feature from their Maven plugin, I decided to write a new plugin which does exactly that. You can read the full story on the QAware blog. We decided to make this Maven plugin open source, and you can find it here.https://www.mkammerer.de/blog/things-i-wish-i-had-known-before-using-mssql-in-production/Mon, 11 Feb 2019 21:35:58 +0100https://www.mkammerer.de/blog/things-i-wish-i-had-known-before-using-mssql-in-production/The project I’m currently working on at work uses a MSSQL database in production. Since then I have learned a lot of things, which I want to summarize here. First: Name every unique constraint, foreign key or default constraint (yes, a DEFAULT clause on a column in MSSQL creates a constraint). If you don’t name your constraint, MSSQL will auto-generate a name for it, and this generated name is not deterministic.https://www.mkammerer.de/blog/visualizing-the-dependencies-between-maven-modules/Sat, 31 Mar 2018 15:57:44 +0200https://www.mkammerer.de/blog/visualizing-the-dependencies-between-maven-modules/I was looking for (and found) a way to visualize the dependencies between the Maven modules in a multi-module Maven project. In other words: draw a graph with the modules as nodes and the dependencies between them as edges. I found this plugin. By default it also shows the 3rd party dependencies, so I had to tweak the configuration a little bit. Running mvn com.github.ferstl:depgraph-maven-plugin:3.0.1:aggregate -DcreateImage=true -DreduceEdges=false -Dscope=compile "-Dincludes=your.group.id*:*" will create the file dependency-graph.https://www.mkammerer.de/blog/noke-reactive-spring-webflux-and-cassandra-note-taking/Wed, 18 Oct 2017 18:37:57 +0200https://www.mkammerer.de/blog/noke-reactive-spring-webflux-and-cassandra-note-taking/Hi, maybe you are interested in a small project I hacked together this afternoon: https://github.com/phxql/noke It’s a note taking software, which is built with the new Spring 5 Webflux. It uses the Spring Data reactive Cassandra repository, so it’s possible to run the whole application non-blocking. I wrote it primarly to learn the Spring Webflux and Project Reactor (the Mono and Flux you see all over the code). It’s pretty cool!https://www.mkammerer.de/blog/git-feature-branching-with-jenkins-and-sonarqube/Thu, 14 May 2015 11:34:37 +0200https://www.mkammerer.de/blog/git-feature-branching-with-jenkins-and-sonarqube/In this article I’m going to explain how to work with git feature branches and get CI with Jenkins and source code metrics with SonarQube. First, open your Jenkins Update center and install the Multi-Branch Project Plugin, the SonarQube Plugin and the Git plugin. Now create a new job, choose the “Freestyle multi-branch project” type. The setting “Sync Branches Schedule” determines how often the plugin should look for added/removed feature branches.https://www.mkammerer.de/blog/introducing-restwars/Wed, 18 Feb 2015 18:45:00 +0100https://www.mkammerer.de/blog/introducing-restwars/In this post, i’m going to introduce my hobby project, RESTwars to you. RESTwars is a multiplayer game like the good old browser games, but with a twist: instead of preventing bots from the game, it encourages bots to play the game. RESTwars itself has no GUI, it is playable, as the name suggests, via a REST interface. The game is set in a sci-fi universe with planets, ships and stuff.
