Although I love lombok, it gives too much problems while configuring sometimes, specially in Linux. When I was trying to install it, I was getting the following error:
Double-click lombok.jar (downloadable from this site, or from your maven repository; it's the same jar).
This starts the eclipse/STS installer which will find eclipse (and eclipse variants as listed above), and offers to install lombok into these eclipse installations. The same tool can also uninstall lombok. Source: https://projectlombok.org/setup/eclipse
