Error:null cannot be cast to non-null type org.jetbrains.kotlin.gradle.internal.WrappedVariantData<*>
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><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
