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'.

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!

Solution 1

After a week's struggle, I finally found the issue.

I added the kotlin-kapt plugin for realm.

And I had a folder named interface itself to hold some interfaces.

I implemented one of the interfaces from the interface folder in MainActivity.

Now the import for the interface was something like this,

import com.android.app.java.interface.Listener

Where, the keyword interface confused the annotation processor, hence caused error while generating stub.

I renamed the folder (from interface to intrface).

That solved the error.

This is a very simple mistake that cost me a week.

Anyway, found the issue. Yay!

Solution 2

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.

Solution 3

I had the same problem. I forgot to add @Dao annotation in my room database

Solution 4

I had the same problem because i had forgotten to add a converter in a list included in entity..In room you have to add converters in order to store lists in databas

Solution 5

check your fields in Model DB maybe you have val, change to var like this:

open class User(var id: Int?= null,
            var name: String? = null,
            var lastName: String? = null): RealmObject()

Check your Dao classes. When converted from java, may make mistake with methods that names start with "get"
