Gradle build failing after update

Question

Getting exception while gradle/gradlew build. Build without test cases is successful. This happening when I updated the gradle to 6.0.1

Works fine for gradle 5.6/6.2 version.

Could not write standard input to Gradle Test Executor 2.

I just had this happen, and found that stopping the gradle daemon resolved it for me:

gradle --stop

or

./gradlew --stop

depending on your setup (the daemon is relaunched when you attempt to build again).
