【问题描述】：
Android Studio 最新更新后，DataBinding 依赖项丢失。我收到此错误消息：
ERROR: Failed to resolve: androidx.databinding:databinding-runtime:3.3.2
Show in Project Structure dialog
Affected Modules: app
ERROR: Failed to resolve: androidx.databinding:databinding-adapters:3.3.2
Show in Project Structure dialog
Affected Modules: app
这是我应用的 build.gradle：
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.soulfetch2"
minSdkVersion 21
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
}
compileOptions {
sourceCompatibility 1.8
targetCompatibility 1.8
}
}
dependencies {
def acraVersion = '5.1.3'
implementation "ch.acra:acra-mail:$acraVersion"
implementation "ch.acra:acra-dialog:$acraVersion"
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'
implementation 'androidx.core:core-ktx:1.1.0-alpha04'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.2-alpha01'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.2-alpha01'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.1.1'
implementation 'androidx.preference:preference:1.0.0'
implementation 'androidx.recyclerview:recyclerview:1.0.0'
implementation "androidx.lifecycle:lifecycle-runtime:2.0.0"
dependencies {
def nav_version = "1.0.0-rc02"
implementation "android.arch.navigation:navigation-fragment-ktx:$nav_version"
implementation "android.arch.navigation:navigation-ui-ktx:$nav_version"
}
}
我尝试添加这些依赖项，但没有效果。
implementation 'androidx.databinding:databinding-adapters:3.3.2'
implementation 'androidx.databinding:databinding-runtime:3.3.2'
通过将这些添加到 gradle.properties 解决了这里的另一个问题，但在我的情况下它导致了另一个额外的错误：
android.enableExperimentalFeatureDatabinding = true
android.databinding.enableV2=true
知道我要做什么吗？
