Impossible de trouver le symbole DataBindingComponent sur le projet Kotlin d'Android Studio 3.2 Canary 16

Question

Je viens de créer un nouveau projet sur Android Studio 3.2 Canary 16 avec Kotlin activé. Puis j'ai également activé la liaison de données, mais je reçois une erreur disant qu'il ne pouvait pas trouver la classe DataBindingComponent.

Voici mon projet gradle :

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

buildscript {
    ext.kotlin_version = '1.2.41'
    ext.android_plugin_version = '3.2.0-alpha10'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0-alpha16'
        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 {
        google()
        jcenter()
    }
}

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

Le fichier gradle de mon module :

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-kapt'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "net.julianonunes.myapp"
        minSdkVersion 22
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dataBinding {
        enabled = true
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    implementation 'com.squareup.okhttp3:okhttp:3.10.0'
    implementation 'com.android.support:design:27.1.1'
    kapt "com.android.databinding:compiler:3.1.2"
}

Le xml de mon activité :

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <data>
        <variable
            name="data"
            type="net.julianonunes.myapp.RegisterData" />
    </data>

    ....
</layout>

Et voici le résultat de la construction :

Executing tasks: [clean, :app:assembleDebug]

Configuration on demand is an incubating feature.

Qu'est-ce qui ne va pas avec mon projet ?

PS : Le problème se pose également avec Android Studio 3.1.2.

Answer 1

Dans mon cas, Si vous utilisez le Dynamic Feature Module :

build.gradle(app)

dataBinding {
    enabled true
}

Ceci doit être activé dans les fichiers gradle Root et Child (n'oubliez pas d'ajouter le plugin kapt).

Answer 2

J'ai essayé classpath 'com.android.tools.build:gradle:3.2.0-beta05' avec et sans dépendance explicite kapt "androidx.databinding:databinding-compiler:3.3.0-alpha06"

Et j'obtiens toujours la même exception.

J'ai également essayé la version 3.3.0-alpha06 mais rien n'a changé.

UPDATE : Après 2 jours, j'ai résolu le problème. Ce que j'ai fait, c'est réparer manuellement tous les fichiers qui avaient des problèmes, à cause de Migration vers AndroidX (mauvais paquets dans les importations et les XML, etc.). En outre, j'ai dû mettre à jour Glide de 4.7 à 4.8. Lorsque j'ai corrigé tous les fichiers rouges, le problème a disparu.

Answer 3

C'est mon erreur la plus stupide ! J'ai en fait créé une variable privée pour le Databinding et c'est ce qui a causé ce problème.

Il suffit d'utiliser un lateinit var binding et ça a marché.

Cela pourrait aider quelqu'un !

Answer 4

Je le répare en mettant à jour Android Studio à Canary 16 ET ceci dans gradle.wrapper.properties distributionUrl=https\://services.gradle.org/distributions/gradle-4.7-all.zip

Answer 5

Dans mon cas, le problème a été résolu en changeant :

androidExtensions.experimental = true

(c'est-à-dire le DSL de gradle en une seule ligne)

à

androidExtensions {
    experimental = true
}

à l'exception de could not find the DataBindingComponent class J'ai aussi error: incompatible types: NonExistentClass cannot be converted to Annotation associé à kotlinx.android.parcel.Parcelize annotation (@Parcelize)
