@graemerocher Hmm... Sorry, I don't know how to get rid of slfj4j initialization correctly. The only way I know to remove this message is to add logback or slf4j-simple to dependencies

[graemerocher]

the code path that initializes SLF4J has to be removed from the compiler.

@graemerocher I went through all the code and all the dependencies. There is no use of slf4j anywhere in the project code itself.

What solutions do I see:

1. Remove the dependency on the swagger-core libraries (I have already done this anyway and will add the PR in the near future). You also need to remove the dependency on the micronaut-http library, because inside it uses slf4j - this is also not difficult to do.

2. Add to dependencies 'org.slf4j:slf4j-nop'

3. Add dependencies 'org.slf4j:slf4j-simple' or 'ch.qos.logback:logback-classic'
