I was just started learning Retrofit2 with Moshi but having difficulty during compilation/building.

This is the error from Build Output

```
Execution failed for task ':app:kaptDebugKotlin'.

A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask$KaptExecutionWorkAction
java.lang.reflect.InvocationTargetException (no error message)
