it's weird because I have this in my dependencies, but of course I don't see that module

|    +--- ch.qos.logback:logback-core:1.2.11 (c)

but I'm filtering logging in my dependencies

  modules {
    module("org.springframework.boot:spring-boot-starter-logging") {
      replacedBy("org.springframework.boot:spring-boot-starter-log4j2")
    }
  }

Comment From: wilkinsona

A replacement alone isn't sufficient, you need to declare a dependency on Log4j2 as well. This is described in the documentation.

This isn't directly related to you r problem but spring-boot-starter-parent is intended for use as the parent of a module built with Maven. When using Gradle, you should use spring-boot-dependencies.

If you have any further questions, please follow up on Stack Overflow or Gitter. As mentioned in the guidelines for contributing, we prefer to use GitHub issues only for bugs and enhancements.

oh... I see what's going on. It's ending up there at the compiletime classpath because something is including it there, I have the log4j 2 starter included as runtime only because I don't having everything it adds on the compiletime classpath. honestly I kind of hate that starters always want me to be able to import all the things. I've made a giant libs.versions.toml just to try to avoid this stuff, and it still fails at a lot of it. This also explains why I really only noticed the problem in intellij.
