How to set sourceDirs with v6?

[gastendonk]

This is 5.0.13 code (Gradle 7.4.2). How can I write this with 6.0.9?

        task runSpotBugs(type: com.github.spotbugs.snom.SpotBugsTask) {
            sourceSets.findAll { s -> s.name != 'test' }.each { s ->
                sourceDirs    = files(sourceDirs,    s.allSource.sourceDirectories)
                classDirs     = files(classDirs,     s.output)
                auxClassPaths = files(auxClassPaths, s.compileClasspath)
                visitors = ['CallToUnsupportedMethod', ...]
            } ...
