I tried this before and it never worked, but after this video I finally got it to work! Thanks! But I got one question, how can I make annotations to generate code into the same class and make it usuable while coding? (Just like Lombok with @Getter, @Setter, etc...)

[@geekific]

Nice! Check this video, it'll answer your question: kzbin.info/www/bejne/jJPGYox-i7x5nsk. Any annotation you create can be usable while coding.

I have similar use case but using custom annotation i want to generate a logger object Something similar to what @sl4j of lombos does. I have done all the steps but unable to get object of my custom logger class when I use the custom class level annotation

[@iamshakiransari]

Excellent 👍 Is it possible to change or modify existing class such as @NotNull annotations?

[@geekific]

You can name the annotations you create anything you want, just take care with your imports!

[@iamshakiransari]

Thanks for replying.. what i meant how to make changes in existing Java class, what you showed it creates a new class

[@Grynjolf]

How do I do it without having to pull in a package?

[@wasim289]

but how process method is getting called?

[@geekific]

When you compile your code, the compiler will call it automatically. You can make use of the command provided at 7:22 and add a break point inside it to make sure it does. Hope this helps! Cheers!

@@geekific This assumes you're using maven as your build tool.
