Cannot set the value of read-only property 'classDirectories' for task '...' of type org.gradle.testing.jacoco.tasks.JacocoReport

Found the response here : https://docs.gradle.org/current/userguide/upgrading_version_5.html#other_deprecated_behaviors_and_apis

And here : Filter JaCoCo coverage reports with Gradle

For example, classDirectories is replaced by classDirectories.from

You'll need to change from classDirectories = SOME_DIRS to getClassDirectories().setFrom(SOME_DIRS).

Works OK with Gradle 6.1.1
