How to Install Lombok for Java Eclipse with Gradle (Windows) Guide

How to Install Lombok in Eclipse

As per Project Lombok, “Lombok is a Java library that automatically plugs into your editor and builds tools, spicing up your Java. Never write another getter or equals method again, with one annotation, your class has a fully-featured builder, automates your logging variables, and much more.”

This blog focuses on installing Lombok into the Eclipse IDE on Windows and additionally features steps specific to Gradle Apps.

Step 1

Download lombok.jar file from here: https://projectlombok.org/download

Step 2

Open the terminal and change the directory to the path where the downloaded file is located.

Step 3

In the terminal, run this command: java -jar lombok.jar

With the above command, an installer will open and automatically scan for the installation of the Eclipse IDE. If you already know the IDE installation location, provide it by clicking the “Specify Location” button.

Step 4

Once the wizard has located the IDE installation location, click the “Install button”. Close the Installer when done.

Step 5

Restart the Eclipse IDE if already running.

Steps Specific to Gradle

Step 6

The Installer will auto-add the dependency to your build.gradle file. If it didn’t, open your build.gradle file and add the following dependencies.

repositories {

mavenCentral()

}

dependencies {

// other dependencies

compileOnly ‘org.projectlombok:lombok:1.18.8’

annotationProcessor ‘org.projectlombok:lombok:1.18.8’

// other dependencies

}

Sync the Gradle build.

Step 7

Run the App.

That’s all. Now you can use Lombok’s annotations to save your efforts and reduce the overall size of your code.

What is Lombok used for in Eclipse?

Lombok is a Java library that automatically generates commonly used code like getters, setters, constructors, and toString methods, reducing manual coding in Eclipse.

How do I know if Lombok is installed correctly in Eclipse?

After installation, restart Eclipse. If you can use annotations like @Getter or @Data without any compilation errors, Lombok is successfully integrated.

Do I need to manually add Lombok to every new project?

Yes, you’ll need to include the Lombok JAR in each project or define it in your Gradle/Maven dependencies to make it available across projects.

Why is Lombok not working in Eclipse after installation?

This may happen if the Lombok JAR isn’t linked correctly to the Eclipse IDE. Re-run the Lombok installer and ensure it’s associated with your Eclipse installation directory.

Can I use Lombok with Gradle in Eclipse?

Absolutely. Just add the Lombok dependency to your build.gradle file and refresh your Gradle project. Eclipse will automatically recognize it once Lombok is configured.

Is Lombok safe to use in production code?

Yes, Lombok is widely used and considered stable for production environments. However, always ensure your team is familiar with Lombok annotations for easier code maintenance.
