Android - Build fails with databinding and kapt with gradle 3.2.1

Question

I'm facing a problem with databinding and kapt I am using kotlin with Android Studio 3.2.1 The problem is when I use kapt (which I have to use I think if I want to use DBFlow), the build fails.

I have tried several solutions I found like invalidating caches and restarting or cleaning the project and rebuilding it, adding or deleting kapt 'com.android.databinding:compiler:3.1.4' but it is apparently useless to add it with the recent versions of kapt

Here is the gradle file of the project

buildscript {
    ext.kotlin_version = '1.3.10'
    ext.dbflow_version = '4.2.4'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        mavenCentral()
        maven { url "https://www.jitpack.io" }
        google()
        jcenter()
    }
}

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

And the gradle file of the app

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

android {
    compileSdkVersion 28

    defaultConfig {
        applicationId "paf.songrecorder"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dataBinding {
        enabled = true
    }

    androidExtensions {
        experimental = true
    }

    kapt {
        generateStubs = true
    }

}

dependencies {
    annotationProcessor "com.github.raizlabs.dbflow:dbflow-processor:$dbflow_version"
    kapt "com.github.raizlabs.dbflow:dbflow-processor:$dbflow_version"

    implementation "com.github.raizlabs.dbflow:dbflow-core:$dbflow_version"
    implementation "com.github.raizlabs.dbflow:dbflow:$dbflow_version"
    implementation "com.github.raizlabs.dbflow:dbflow-kotlinextensions:$dbflow_version"

    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'

    implementation 'com.android.support:recyclerview-v7:28.0.0'

    implementation 'com.squareup.retrofit2:retrofit:2.4.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.3.0'

    implementation 'com.android.support:design:28.0.0'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

When the app is building it can't find in the DataBinderMapperImpl class the BindingImpl classes

[Edit]

I have this error without adding the line :

import paf.songrecorder.databinding.SongBindingImpl; ^ symbol: class SongBindingImpl location: package paf.songrecorder.databinding – PAF 11 mins ago

And after adding kapt "com.android.databinding:compiler:$android_plugin_version" :

Do you have any idea of what could be the cause of this issue?

Answer 1

Please refer to answer at https://stackoverflow.com/a/54071510/1726296

As of Android Studio 3.2, this kapt plugin is no longer required.

However, without this plug in, the error message in case of any error, while compiling is cryptic. So, only option now it seems now is to downgrade your Gradle version to 3.1.4.
