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.

Never seen that before, but a ClassNotFoundException could indicate that your Gradle installation is corrupted somehow. If you have a working version, try running gradle wrapper with that to regenerate the wrapper scripts. If it still doesn't work, try deleting the broken distribution in $HOME/.gradle/wrapper/dists. – Domett

anyone found the issue ? I am getting this, and clearing gradle cache, wrapper didn't help – Salford

since this is the underlying issue, can you feature it a little bit more prominently: Caused by: java.lang.ClassNotFoundException: worker.org.gradle.process.internal.worker.GradleWorkerMain the answer given is also the appropriate one, so it would be great if it was accepted – Juliettajuliette

Answer 1

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).

i just hit this issue and this answered absolutely helped, thank you! – Vizierate

Answer 2

I encountered this error and the one method I found was dump the whole $HOME/.gradle cache and then rebuild the project.

Starting/Stopping IntellijIDEA and/or rebuilding did not help.

You know you have jumped the complexity shark somewhere when running lowly test cases starts to fail for obscure reasons.

Granted, this happened after a machine crash. But still..

Answer 3

If its a windows system, then try deleting the .gradle folder from the user directory and try to build the gradle. This should solve the issue
