I am facing problem to install Lombok on Eclipse, it shows an Error message attached screenshot.
I also tried with root (with sudo) user or with command sudo java -jar lombok.jar . I am using ubuntu 20.04 LTS. Kindly help, how I install lombok?
The reason behind this is, you've installed eclipse via snap. Snap is immutable directory, so you cannot add/update code in it.
There are two options to achieve your goal :
Opt 1 -> Create your own eclipse.ini file that runs with lombok. Here is a good description.
Opt 2 -> Uninstall eclipse from snap, install it via eclipse web page, than you can surely add your lombok plugin with installer.
