Any updates on this issue please?

This problem is caused by the Gradle task writing the following to the build.gradle file

// build.gradle
classDirectories.setFrom fileTree(dir: "build/classes/java/main/").exclude(jacocoExcludes).include(jacocoIncludes)

In Gradle 6.x and later, classDirectories is read-only.
JacocoReport - Gradle DSL Version 7.6.1

In Gradle 5.x, it was possible to write values to classDirectories, so the problem did not occur.
JacocoReport - Gradle DSL Version 5.6.4

I have the same problem. I'm getting the following error: The value for this file collection is final and cannot be changed.
