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

Question

Please help. I use room. But I have such a mistake. If you remove this code

@Database(
entities = [Current::class],
version = 1
)

But I definitely need it to be in my code otherwise everything will be wrong.

This my ForecastDatabase.kt

package com.ggenius.whattowearkotlin.data.db

import android.content.Context
import androidx.room.Database
import androidx.room.Room
import androidx.room.RoomDatabase
import com.ggenius.whattowearkotlin.data.db.entity.Current

@Database(
    entities = [Current::class],
    version = 1
)
abstract class ForecastDatabase : RoomDatabase() {
    abstract fun currentWeatherDao(): CurrentWeatherDao

    companion object {
        @Volatile private var instance: ForecastDatabase? = null
        private val LOCK = Any()

        operator fun invoke(context: Context) = instance ?: synchronized(LOCK) {
            instance ?: buildDatabase(context).also { instance = it }
        }
        private fun buildDatabase(context: Context) =
            Room.databaseBuilder(context.applicationContext,
                ForecastDatabase::class.java, "forecast.db")
                .build()
    }
}

Its my gradle. Check Room

    id 'com.android.application'

In this screenshot, there is an error due to which my application does not start enter image description here

Answer 1

You don't appear to have implementation 'androidx.room:room-ktx:2.4.0' in the build gradle.
