After discussing the ApplicationIndexBuildItem and CombinedIndexBuildItem, let’s continue exploring Quarkus build items with the AdditionalBeanBuildItem. This build item is part of the configuration items for the Arc library , which handles dependency injection in Quarkus. Quarkus and Dependency Injection Quarkus heavily relies on dependency injection, allowing for loose coupling between different objects in a Quarkus application. Quarkus uses a library called Arc that automatically scans the application’s classpath and references all classes declared as beans (e.

Quarkus has a very powerful extension system based on the concept of BuildItem. Each BuildItem allows you to configure an extension in a specific way. However, the documentation for these BuildItems is very incomplete. Among the hundreds of BuildItems that exist, I propose to study two of them in this post. Let’s focus on ApplicationIndexBuildItem and CombinedIndexBuildItem. A Story of Jandex Quarkus needs to gather information about the application at build time.
