![]() ![]() After all, these discussed usages are very commonly put together in many cases. ![]() Lombok annotations: Lombok provides a set of annotations to make our coding life easier. Enable annotation processing in Intellij: Preferences -> Build,Execution,Deployment -> Compiler -> Annotation Processors -> Enable Annotation processing. If you take a look at Lombok.sneakyThrow() source code, you'll see that it eventually does two things: A null. How many of them did you know Photo by Sabri Tuzcu on Unsplash Lombok is a Java library that can generate known. You will see project Lombok installed there. Add lombok to your dependency, and make sure the package is downloaded properly. The answer is that Lombok cheats the compiler - but what you've shown is a decompiled version of the compiled byte code - and the JVM running the byte code does not distinguish between checked and unchecked exceptions: it does not care. If the features from the annotations we’ve reviewed so far are of interest, we may want to examine and annotations too, as they behave as if a set of them had been applied to our classes. Feb 2 - 5 Explaining each of the 16 annotations in less than 20 seconds. Let’s consider this class we want to use as a JPA entity: class User implements Serializable ). Install the Lombok plugin: Settings > Plugins > Lombok. Right-click on that lombok-'version'.jar > Run As > Java Application (similar to double-clicking on the actual jar or running java -jar lombok-'version'.jar on the command line.) A GUI will appear, follow the instructions and one of the thing it does is to copy lombok.jar to your IDEs root. However, new Java language or compiler versions may result in new types of warnings or new deprecations. Typically, Lomboks code will not produce any warnings. However, this code needs to live in our sources and be maintained when a new property is added or a field renamed. Apart from other answers to enable annotation processing in Intellij IDE, we need to add a plugin to make the IDE understand Lombok Project. The question remains why Lombok would generated those suppression annotations. This is so common that most IDE’s support auto-generating code for these patterns (and more). Lombok is a popular library in the Java ecosystem that provides a variety of annotations to simplify common development tasks. Encapsulating object properties via public getter and setter methods is such a common practice in the Java world, and lots of frameworks rely on this “Java Bean” pattern extensively (a class with an empty constructor and get/set methods for “properties”).
