If in case eclipse installation path is not detected then you need to manually click on Specify location and browse to the installation path. For example, in our case it is installed on /home/cyberithub/eclipse/java-2023-06/eclipse/eclipse path as you can see below. Once detected, click on Install/Update to proceed.
Lombok will be installed successfully and you should see below window with Install successful message. You can now quit the installer by clicking on Quit Installer and then restart your Eclipse IDE.
Once you restart eclipse IDE, you have to go to Help -> About section and look for Lombok version installed. If it shows like below then it confirms Lombok installed successfully in Eclipse IDE. Now you can start adding lombok.jar and build your projects.
