How can I solve this error : Data Binding annotation processor version needs to match the Android Gradle Plugin version

Question

我正在尝试对我的项目进行数据绑定，但我的 Gradle 文件中出现此错误我是初学者，所以让我知道您需要哪些文件或您还需要哪些其他信息？

Data Binding annotation processor version needs to match the Android Gradle Plugin version. You can remove the kapt dependency androidx.databinding:databinding-compiler:7.1.0-alpha01 and Android Gradle Plugin will inject the right version.

build.gradle (:app)

plugins {
    id 'com.android.application'
    id 'kotlin-android'
//    id 'kotlin-android-extensions'
    id 'kotlin-kapt'
    id 'kotlin-parcelize'
//    id "androidx.navigation.safeargs.kotlin"
    id 'androidx.navigation.safeargs.kotlin'
}

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

defaultConfig {
    applicationId "com.example.todoappstevdzaskillshare1"
    minSdkVersion 26
    targetSdkVersion 30
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
    jvmTarget = '1.8'
}

dataBinding {
    enabled = true
 }
} 

 dependencies {

implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'androidx.core:core-ktx:1.5.0'
implementation 'androidx.appcompat:appcompat:1.3.0'
implementation 'com.google.android.material:material:1.3.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

//DataBinding
kapt 'androidx.databinding:databinding-compiler:7.1.0-alpha01'

// Navigation Component
implementation 'androidx.navigation:navigation-fragment-ktx:2.3.5'
implementation 'androidx.navigation:navigation-ui-ktx:2.3.5'

// Room components
implementation "androidx.room:room-runtime:2.3.0"
kapt "androidx.room:room-compiler:2.3.0"
implementation "androidx.room:room-ktx:2.3.0"
androidTestImplementation "androidx.room:room-testing:2.3.0"

// Lifecycle components
implementation "androidx.lifecycle:lifecycle-extensions:2.2.0"
implementation "androidx.lifecycle:lifecycle-common-java8:2.3.1"
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.1"

}

注意：让我知道您还需要哪些文件，我会编辑问题。

您需要删除这行代码kapt'androidx.databinding:databinding-compiler:7.1.0-alpha01'并重新编译。根据Google的open databinding文档，打开databinding的方法是：

android {
        ...
        dataBinding {
            enabled = true
        }
    }

我认为您的 gradle 中已经启用了数据绑定。所以只要删除依赖，应该不会出现这个错误。
