In response to this problem, Project Lombok was created. This issue is a common pain point for developers and can be exemplified by tens or even hundreds of lines of getter and setter methods per source file, as well as extensive class constructors. In Object-Oriented Java development, the necessity of ensuring the encapsulation and immutability of objects only adds to the amount of boilerplate code required. Java developers, particularly those coming from other programming languages, have long complained about the overwhelming amount of boilerplate code found in Java codebases. Lombok provides the annotation which can provide useful information in case of NullPointerException.Lombok: The Good, The Bad, and The Controversial Private String address = "22B Baker Street" This generates public Accessors (the Getter and the Setter methods) for those fields (you can see those methods in the “Outline” view in case of Eclipse IDE) during the compilation process. annotations can be used at individual field levels too. Lombok simplifies this by providing and annotations at a class level which, by default, annotates all the non-static fields in that class with the and annotations in the background. At that time, I simply thought that why should someone write this long repetitive, low-value code which contains only the setters and getters for all the fields. Lombok – Accessors time when I encountered this feature, I instantly remembered a long POJO class which I wrote once for Serialization. m2 repositories respectively) -> a wizard will open up -> check and select for IDE (if the wizard recognizes your IDE) -> if IDE is not recognized, navigate to the location where the IDE is setup by clicking on “Specify Location…” -> Click Install/Update -> “Install Successful” will be displayed -> Restart Eclipse -> And you are good to go. To configure and add it as plugin, click on the lombok.jar file (for gradle and maven you can find it inside the. ProvidedCompile group: 'org.projectlombok', name: 'lombok', version: '1.18.12'įor Maven, add the below dependency in the pom.xml file Īlso, remember to configure Lombok to your IDE (and ask other team members to add to their IDE as well), otherwise it won’t compile. I mostly use Gradle, so I add the below dependency to my adle files. Or we can add Lombok as dependency to our build tools as well, like Gradle and Maven. To use Lombok in our code, we need to download and add the Lombok jar to our classpath. Amazing, isn’t it? Thanks to the guys who created and contributed to the “ProjectLombok”. In the backend, it automatically compiles from the annotations used for the boilerplate code and generates the byte code in the “.class” files instead of the boilerplate code actually being written in the source files by the programmer. Java code becomes too verbose sometimes forcing the coders to write a lot of low-value- repetitive, error-prone code which actually perform minimal tasks (boilerplate code). Thereby, making our Java code shorter, cleaner, simpler, more manageable and readable. It can get plugged in our IDE of choice, be it Eclipse/ Netbeans/ IntelliJIDEA/ STS/ VSCode, and using annotation processor it generates those code for our programs during compilation. It uses annotations to specify which boilerplate code do we want Lombok to implement for us. Lombok is a java library which acts as a pre-processor and eliminates the need for Java coders to write some standard boilerplate code. I decided to give it a try and this blog post is a summarization of what I learnt about Lombok and its annotations (along with step-by-step setup of Lombok). While going through a long list of comments in a Twitter thread last month, I came to know how popular, productive and time-saver this library is for the programmers who code in Java. I came to know about this powerful Java library “Lombok” last year from a colleague of mine when we were debugging an issue related to automation logs, but didn’t get time since to dig deep into it.
