Lombok Not Running in IntelliJ

Question

I downloaded a project from my companies source repo. In this project there are lines such as the following:

@RequiredArgsConstructor(onConstructor = @_(@Inject))

Given the language level this does not compile as _ is a reserved keyword. What is (apparently) supposed to happen is that, as a precompilation step, lombok replaces the underscore. However this does not occur.

I am using IntelliJ 2022.3.1 which comes with lombok preinstalled and it doesn't seem as if uninstalling and reinstalling is an option. Any help would be appreciated.

Answer 1

Consider downgrading SDK and language level to Java 1.8

Use of '_' as an identifier is not supported in releases since Java 9

also worth checking that annotation processing is enabled

Preferences -> Build, Execution, Deployment -> Compiler -> Annotation Processors -> Enable annotation processing
