GradleException when multiple goals leave behind spotless-clean dir

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

リンクされている openapi-generator-client プロジェクトで次のシーケンスを再現することから始めます: `gradle clean openApiGenerate spotlessApply`。続けて `gradle spotlessCheck` または `gradle build` を実行します。生成された `build/spotless-clean/spotlessJava/build/generate-resources/main/src/main/java/` ディレクトリを調べ、別途 `spotlessApply` を実行した場合、または明示的なターゲットを指定した場合の動作と比較します。後続のチェックまたはビルドが手動でクリーンアップせずに成功すれば完了です。
