I can't get Jacoco excludes to work

[xenomachina]

My root project's build.gradle.kts contains:

import org.kordamp.gradle.plugin.base.ProjectConfigurationExtension

// ...

plugins {
    // org-kordamp-gradle-jacoco = "org.kordamp.gradle.jacoco:0.54.0"
    alias(libs.plugins.org.kordamp.gradle.jacoco)
}

// ...

config {
    coverage {
        jacoco {
            enabled = true
            excludes = setOf(
                "**/com/example/foo/bar/*",
            )
        }
    }
}

When I run aggregateJacocoReport, an aggregate HTML report is produced at build/reports/jacoco/aggregate/html/index.html

This report always contains all of the classes from the subprojects, no matter what I put in excludes. It behaves exactly as if I hadn't specified any excludes. I've even tried excluding "**", and still doesn't seem to exclude anything from the aggregate report.

Does excludes work for anyone else?

Is there any way I can debug this to figure out where the excludes are getting "dropped"?

I'm using Gradle 8.5 on 21.0.2 JVM.

It looks like people have also reported a similar problem with the jacoco-report-aggregation
plugin.
