>          Issue Type: Bug
>          Components: unit tests
>    Affects Versions: 3.6.0

> On current dev branch, gradle 8.x fails while trying to generate test coverage reports as stated in the README, e.g. by running "./gradlew clients:reportCoverage -PenableTestCoverage=true -Dorg.gradle.parallel=false". The error message states:
> "Could not set unknown property 'enabled' for Report html of type org.gradle.api.reporting.internal.TaskGeneratedSingleDirectoryReport"
> In "build.gradle", the library "jacoco" which is used to generate test coverage reports for the Java code is configured in two different places with these settings:
> jacocoTestReport {
>     dependsOn tasks.test
>     sourceSets sourceSets.main
>     reports {
>         html.enabled = true
>         xml.enabled = true
>         csv.enabled = false
>     }
> }
> With the latest version of jacoco, shipped with gradle 8.x, these config options are not compatible anymore. A correct configuration might look like like this:
> jacocoTestReport {
>     dependsOn tasks.test
>     sourceSets sourceSets.main
>     reports {
>         html {
>           required = true
>         }
>         xml {
>           required = true
>         }
>         csv {
>           required = false
>         }
>     }
> }
> However, even with these settings being accepted by Gradle, I was unable to generate any test coverage report. This might be due to some OOM issues, but I tried a lots of settings including increasing the maximum heap for the JVM gradle tasks without getting this to work.
