: Android SDK 30 requires Java 9 (have Java 8). Tests won't be run on SDK 30 unless explicitly requested.?

I am developing android todo app but when I run the project I am getting following error and warnings com.intellij.rt.junit.JUnitStarter -ideVersion5 -junit4 com.example.todo.TodoRoomRepositoryTest [Robolectric] WARN: Android SDK 29 requires Java 9 (have Java 8). Tests won't be run on SDK 29 unless explicitly requested. [Robolectric] WARN: Android SDK 30 requires Java 9 (have Java 8). Tests won't be run on SDK 30 unless explicitly requested. WARNING: No manifest file found at .\AndroidManifest.xml. Falling back to the Android OS resources only. To remove this warning, annotate your test class with @Config(manifest=Config.NONE). No such manifest file: .\AndroidManifest.xml

java.lang.IllegalStateException: Could not initialize plugin: interface org.mockito.plugins.MockMaker (alternate: null)

I have followed following stackoverflow answer Does Robolectric require Java 9?

but it did not solve my issue below my test class in kotlin
