How to find error in spring processAot task?

Question

I'm changing my application to the new spring boot 3.0.5 with native graal.

When executing the processAot task the error below happens:

Task :app:processAot

Even using --stacktrace or --debug the error message remains the same. I have already removed all VOID methods, however, without success. I can't know which method the error refers to.

Does anyone have any idea how I can try to make the error more specific?

I still haven't figured out how to make the AOT error messages more specific, but I found my problem. If anyone else needs it, AOT doesn't understand spring beans with VOID return.

I had a @Bean that didn't return anything:

@Configuration
class BouncyCastleConfig {

  @Bean
  fun addProviders() {
    Security.addProvider(BouncyCastleProvider())
  }
}

I switched to something static:

@Configuration
class BouncyCastleConfig {

  init {
    Security.addProvider(BouncyCastleProvider())
  }
}

an `@Bean` with a `void` return type is strange and is probably a sign you are doing something wrong and should use proper initiailization callbacks instead of this. – M. Deinum Apr 12 '23 at 06:31

yes, it really was an error, but the reported problem is not the Bean itself, it is the little information in the stacktrace in processAOT to inform what is wrong – Rafael Firmino Apr 12 '23 at 12:44
