GradleException when multiple goals leave behind spotless-clean dir

Inizia riproducendo la sequenza nel progetto openapi-generator-client collegato: gradle clean openApiGenerate spotlessApply, seguita da gradle spotlessCheck o gradle build. Ispeziona la directory generata build/spotless-clean/spotlessJava/build/generate-resources/main/src/main/java/ e confronta il comportamento con un'esecuzione separata di spotlessApply o con un target esplicito; l'attività è completata quando il controllo o la build successiva riesce senza pulizia manuale.

In my project: https://github.com/sixcorners/openapi-generator-client/tree/7b2dfb9cda3fe366f0a45f76b60b1a1961311d65
If you run
gradle clean openApiGenerate spotlessApply
it leaves behind a build/spotless-clean/spotlessJava/build/generate-resources/main/src/main/java/ directory. If you then run gradle spotlessCheck or gradle build it throws an error:

Caused by: org.gradle.api.GradleException: There were 0 lint error(s), they must be fixed or suppressed.
Resolve these lints or suppress with `suppressLintsFor`
        at com.diffplug.gradle.spotless.SpotlessCheck.performAction(SpotlessCheck.java:85)
        at com.diffplug.gradle.spotless.SpotlessCheck.performAction(SpotlessCheck.java:57)

if you delete build/spotless-clean or just run gradle spotlessApply again then gradle build works again.
kind of annoying but it's not a big deal.
specifying the target manually also fixes it.

spotless {
  java {
    googleJavaFormat()
    target("src/main/java", "build/generate-resources/main/src/main/java")
  }
  kotlinGradle { ktfmt() }
}

I kind of thought the bug was something else but that disappeared so I kind of wonder if this can even be reproduced on other people's machines or if it will disappear too. It's also not a big deal since you can just run gradle spotlessApply in it's own cli invocation. Also running the build gradle goal in IntelliJ doesn't reproduce the issue. It's very fiddly. If you have trouble reproducing it I wouldn't mind if you just close this issue and leave it as a place for other people to find if they have something similar happen.
This is my gradle version running in a snap:

$ gradle --version
