I am facing this problem from some few days.
When I try to build the project gradle thorws this message.
I cleaned the project re downloaded the dependencies but still problem has not be solved.
Help me to find out the fix.
Error:org.gradle.api.internal.changedetection.state.DefaultFileCollectionSnapshotter$FileCollectionSnapshotImpl cannot be cast to org.gradle.api.internal.changedetection.state.OutputFilesCollectionSnapshotter$OutputFilesSnapshot
Possible causes for this unexpected error include:<ul><li>Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
<a href="syncProject">Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
<a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
