Error in setting up realm with kotlin

Question

I am using some kotlin classes in an existing Android project(already having realm), the kotlin classes are not using any realm feature, now on runtime I am getting this error

:app:compileDebugKotlin
Using kotlin incremental compilation
:app:compileDebugJavaWithJavac
Destination for generated sources was modified by kapt. Previous value = /home/debu/AndroidStudioProjects/WT_Application/app/build/generated/source/apt/debug

error: Annotation processor '__gen.AnnotationProcessorWrapper_debug_io_realm_processor_RealmProcessor' not found
1 error

:app:compileDebugJavaWithJavac FAILED
:app:copyDebugKotlinClasses SKIPPED

FAILURE: Build failed with an exception.

my app's build.gradle

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'realm-android'

android {
    def globalConfiguration = rootProject.extensions.getByName("ext")

allprojects {
    ext {
        androidApplicationId = 'com.wandertrails'
        androidVersionCode = 1
        androidVersionName = "1.0"
        testInstrumentationRunner = "android.support.test.runner.AndroidJUnitRunner"
        testApplicationId = 'com.wandertrails.test'
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Now can someone kindly figure out what is the reason of this error????

Please try to add the annotation processor dependencies to the `kapt` configuration as well: `kapt presentationDependencies.daggerCompiler`, `kapt presentationDependencies.butterKnifeCompiler`, and see if it works. — hotkey, May 18 '17 at 12:58
now I am getting the following error - Error:Circular dependency between the following tasks: :app:compileDebugKotlin \--- :app:kaptDebugKotlin \--- :app:compileDebugKotlin (*) (*) - details omitted (listed previously) — Debu, May 18 '17 at 13:14
If you are using Android Gradle plugin 3.0.0-alpha1, then the circular dependency is a known issue caused by Data Binding, please see http://stackoverflow.com/questions/44035504/how-to-use-data-binding-and-kotlin-in-android-studio-3-0-0; Probably the workaround described there (reverting to Kotlin 1.1.2-2 and disabling IC) will fix this. — hotkey, May 18 '17 at 13:26

3

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'realm-android'

And

kapt presentationDependencies.daggerCompiler
kapt presentationDependencies.butterKnifeCompiler

Might fix it.

after adding the lines errors are gone - annotationProcessor presentationDependencies.daggerCompiler annotationProcessor presentationDependencies.butterKnifeCompiler kapt presentationDependencies.daggerCompiler kapt presentationDependencies.butterKnife kapt "com.android.databinding:compiler:2.3.2" now a new problem arrives, butterknife not working(BK ver - 8.6.0, Gradle ver - 3.4.1) – Debu May 19 '17 at 06:58
@Debu Would you please accept this answer? This question has nothing to do with Butterknife. You'll want to open a new question for that. – G. Blake Meike May 19 '17 at 18:40
