android - After adding Kapt plugin - A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution

Question

First of all,

I'm pretty much aware that a lot of questions on this error had been posted already here, and none of them seems to be having a proper solution especially the one I need.

I'm stuck with the following error for over a week.

I'm working on an android project which is being built using Kotlin, MVVM, Clean Arch, and Navigation Components.

I recently added realm database, and for that I had to add the following plugins.

apply plugin: 'kotlin-kapt'

apply plugin: 'realm-android'

The real problem started from here I think.

(After that I added a DatabaseManager class which makes use of some realm extension functions I wrote to make db operations.)

When I compile the project after this, the following error occurred overall.

A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution

Along with the following

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:kaptDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution
   > java.lang.reflect.InvocationTargetException (no error message)

It points to my MainActivity class which is unaltered and doesn't seem to have any errors or typos for that matter. I'm pretty much sure that the kapt annotation processor does some dirty job here that I do not seem to figure out.

I will be greatly relieved if I could get past this weird error.

Additional note:

1. I have separated my entire project into three modules. All three got kapt plugin (just incase)

2. I use Koin for DI

Hope someone will help me out!

Answer 1

Replacing

kapt "android.arch.persistence.room:compiler:$room_version"

by

implementation "androidx.room:room-runtime:$room_version"
kapt "androidx.room:room-compiler:$room_version"

might fix it as well.
