How to compile and install Stunt Rally on Fedora

Stunt Rally is an open source racing game, one of a few available for Linux. It caught the attention of my son because it supports network mutiplayer mode as well as split screen multiplayer mode.

If you do not want those for any reason, you might find this compilation guide useful. Read more...

Grouping Quarkus extension tests for faster execution

Testing is a substantial ingredient of software quality. Projects producing Quarkus extensions are not an exception. While testing on traditional JVMs is rather fast and well understood, testing GraalVM native executables brings new challenges, especially because it takes long: It is one or more minutes for common test projects that we have in Camel Quarkus. Multiply it with our ~300 extensions and you end up with tens of hours for a single pass of the CI. Let’s discuss some ways how to speed up the native testing, esp. by merging several test modules into a single test module. Read more...

When -DskipTests is not fast enough: skip Maven mojos properly

-DskipTests is a well known way to skip the execution of unit tests during a Maven build and thus save time. This is handy e.g. after pulling the changes from a team git repository which are supposed to have been tested by a CI already. Read more...

History of Camel Quarkus from the very beginning to 1.0.0

I have originally written this for the upcoming Camel Quarkus 1.0.0 announcement, but then decided to remove it from there based on some review comments. I still think the history deserves to be written somewhere, so I am pasting it here. Read more...

Resuming large Maven releases

I happen to have released large Maven projects with hundreds of modules many times in the past and I am doing it right now as well for Camel Quarkus. The current Camel Quarkus 1.0.0-CR3 release comprises 694 Maven modules. That’s rather big. Read more...
