exclude configuration works with classes, so the
.class extension is relevant in specifying the path.
In this post, I’ll be using Swagger to build a REST API with Java and Spring Boot. Swagger is an API framework. It uses a YAML-based language to define an API and it has a code generator that supports multiple languages.

In this post I’m using the Maven Enforcer plugin to break the build when certain files don’t follow the expected naming convention. It’s always a good idea to take the time and implement these checks inside the build pipeline. The alternative is hoping that code reviewers will spot the problems, which is a manual, tedious and error prone approach. Automate all the things!

A little bit more than a month ago, I created an improved Maven archetype project. Similar to the default quickstart archetype, but for Java 8 and with recent jUnit dependency. In order for someone to use it, they’d have to clone the repo, as I had not published it in Maven. After a bit of studying, I figured out what is needed to make the package public. More importantly, I implemented the process in Travis, so that a new version gets published automatically.

In this post we’ll create a small Java application, run it inside a Docker container, and use IntelliJ IDEA to debug. The source code is available here. This is a rather large post, so take your time.

Code Coverage is a useful set of metrics that show you how much of your code you’re impacting during testing. It doesn’t say much about the quality of your tests (you can read more in the old post What is code coverage?), but a 30% coverage is definitely worse than 90%. Let’s see how we can use JaCoCo to see our code coverage in the Java world. We’ll check a few options to use it, such as using it manually, using it within a CI, breaking the build with it, etc. The assumption is we’re working with a Maven project.
