Android, Realm, Gradle: Error:Annotation processor: RealmProcessor not found

Question

Android Studio 2.3.3

My project bulid.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.1.3'
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'com.google.gms:google-services:2.0.0-alpha6'
        classpath "io.realm:realm-gradle-plugin:3.5.0"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url 'https://dl.bintray.com/jetbrains/anko' }
    }
}

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

My app build.gradle.

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
    mavenCentral()
}

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.0"
    dexOptions {
        jumboMode = true
    }

    defaultConfig {
        applicationId "my.project.com"
        minSdkVersion 15

        }
    }

    // exclude buildTypes = "debug" from build Variants
    variantFilter { variant ->
        if (variant.buildType.name.equals('debug')) {
            variant.setIgnore(true);
        }
    }

    buildTypes {
        def APP_NAME_STAGE = "My project Stage"
        def APP_ID_SUFFIX_STAGE = ".stage"

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

    lintOptions {
        abortOnError false
    }
}

def AAVersion = '4.3.0'

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    compile('com.digits.sdk.android:digits:1.11.0@aar') {
        transitive = true;
    }
    compile('com.crashlytics.sdk.android:crashlytics:2.6.0@aar') {
        transitive = true;
    }
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.volley:volley:1.0.0'
    compile 'com.baoyz.swipemenulistview:library:1.3.0'

    compile 'org.jetbrains.anko:anko-sdk15:0.9.1'
    annotationProcessor "org.androidannotations:androidannotations:$AAVersion"
    compile "org.androidannotations:androidannotations-api:$AAVersion"
    testCompile 'junit:junit:4.12'
}

And project bulid and run success. So now I want to add Realm. I add in build.gradle

apply plugin: 'realm-android'

And as result I get error.

Error:Annotation processor '__gen.AnnotationProcessorWrapper_stage_io_realm_processor_RealmProcessor' not found Error:Execution failed for task ':app:compileStageJavaWithJavac'.

Compilation failed; see the compiler error output for details. :app:compileDevJavaWithJavac Destination for generated sources was modified by kapt. Previous value = myProject\app\build\generated\source\apt\dev error: Annotation processor '__gen.AnnotationProcessorWrapper_dev_io_realm_processor_RealmProcessor' not found

Answer 1

I found solution. Two approach:

1. By apt plugin

in app's budile.gradle:

apply plugin: 'com.neenbedankt.android-apt'

apt {
    arguments {

        resourcePackageName android.defaultConfig.applicationId

        androidManifestFile variant.outputs[0]?.processResources?.manifestFile
    }

}

dependencies {
apt 'io.realm:realm-android-library:3.5.0'
apt "org.androidannotations:androidannotations:$AAVersion"
}

OR

2. By kapt plugin

   apply plugin: 'kotlin-kapt'
   
   kapt {
   
       arguments {
   
           arg( "resourcePackageName", android.defaultConfig.applicationId)
   
           arg( "androidManifestFile", 
   
           variant.outputs[0]?.processResourcesTask?.manifestFile)
   
       }
   
   }
   

   dependencies {

   kapt 'io.realm:realm-android-library:3.5.0'
   
   kapt "org.androidannotations:androidannotations:$AAVersion"
   

   }

Answer 2

If you use Kotlin, then you'll need to use KAPT.

annotationProcessor "org.androidannotations:androidannotations:$AAVersion"

should be

kapt "org.androidannotations:androidannotations:$AAVersion"

and

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

should be

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

and

 //       javaCompileOptions {
 //           annotationProcessorOptions {
 //               arguments = ["resourcePackageName": android.defaultConfig.applicationId]
 //           }
 //       }

kapt {
    arguments {
        arg('resourcePackageName', android.defaultConfig.applicationId)
    }
}

EDIT: based on https://stackoverflow.com/a/34708575/2413303

kapt {
    arguments {
        arg('androidManifestFile', variant.outputs[0]?.processResources?.manifestFile)
        arg('resourcePackageName', android.defaultConfig.applicationId)
    }
}

If that still doesn't work, then the question becomes AndroidAnnotations related.
