Question

我正在尝试基于MVVM创建一个新项目，并添加了所需的所有依赖项。到目前为止，这是我添加并完成的操作：

在gradle文件中添加了依赖项
添加了插件
启用dataBinding为true
在gradle文件中添加了类路径类路径“ androidx.navigation：navigation-safe-args-gradle-plugin：2.1.0-alpha05”
添加了android.databinding.enableV2 = true 在gradle.properties内部

我正在关注此youtube播放列表中的指南：

到目前为止我尝试过的东西：

我已经检查过 android.useAndroidX = true和android.enableJetifier = true
替换为gradle文件中的minifyEnable false

该应用程序甚至无法编译并且一直显示错误

这是我的gradle项目文件：

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

    buildscript {
ext.kotlin_version = '1.3.50'
repositories {
    google()
    jcenter()

}
dependencies {
    classpath 'com.android.tools.build:gradle: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

    classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.1.0-alpha05"
}
    }

    allprojects {
repositories {
    google()
    jcenter()

}
    }

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

这是我的gradle Module：app文件：

    apply plugin: 'com.android.application'

    apply plugin: 'kotlin-android'

    apply plugin: 'kotlin-android-extensions'

    //kotlin kapt and navigation safeargs plugin
    apply plugin: 'kotlin-kapt'

    apply plugin: "androidx.navigation.safeargs"

    android {
compileSdkVersion 28
defaultConfig {
    applicationId "com.example.mvvmsampleapp"
    minSdkVersion 22
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }

}

dataBinding {
    enabled = true
}
    [This is the error][1]}

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

implementation 'com.xwray:groupie:2.3.0'
implementation 'com.xwray:groupie-kotlin-android-extensions:2.3.0'
implementation 'com.xwray:groupie-databinding:2.3.0'

    }

这是我的错误消息

    /Users/garylim/Downloads/MVVMSampleApp/app/build/generated/source/kapt/debug/com/example/mvvmsampleapp/DataBinderMapperImpl.java:9: error: cannot find symbol
    import com.example.mvvmsampleapp.databinding.ActivityLoginBindingImpl;

      symbol:   class ActivityLoginBindingImpl
      location: package com.example.mvvmsampleapp.databinding

P.S。无法发布图片

添加具有此错误的依赖项后，谁知道如何解决？
