This is a guest blog post from Iván López, one of the core members of the Micronaut and Grails development team at OCI In November 2019, IntelliJ IDEA introduced support for Micronaut, making it even easier to build fast, lightweight microservices and serverless applications with the framework. As JetBrains continues to add more Micronaut features to IntelliJ IDEA, the Micronaut team at Object Computing finds that the two technologies work extremely well together. Here are five specific features that make the Micronaut IntelliJ IDEA combo a terrific tool for any developer looking to boos

IntelliJ IDEA 2020.1 EAP has just been updated. The new build can render Javadocs right in the editor and enables you to create and split terminal sessions, vertically or horizontally, multiple times. In-editor Javadocs rendering Split terminal sessions vertically/horizontally In-editor Javadocs rendering Reading Javadocs in the editor might be annoying because of all the tags you have to cut through, especially when you need to interact with the reference links and images. This is why we’re adding a way to render Javadocs right in the editor. To enable this new experimental feature, g

We have Java Dataflow Analysis (DFA), which is able to derive facts about your program: possible exceptions, conditions that are always true/always false, and more. It performs an abstract interpretation of the source code, allowing it to gather information about the code execution before the code is executed. However, it knows almost nothing about the inputs to the code. Well technically, if the method parameter is annotated as `@NotNull` the analysis trusts this annotation and assumes that `null` cannot appear here, but this is only a tiny bit of information. On the other hand, we have th
