android - 最新 Android Studio 更新 3.3.2 后 Unresolved DataBinding 依赖关系

Question

在最新更新到 Android Studio 之后，DataBinding 依赖项丢失了。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

这是我应用程序的 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，但在我的案例中它导致了另一个额外的错误:

android.enableExperimentalFeatureDatabinding = true
android.databinding.enableV2=true

知道我必须做什么吗？

Answer 1

AS 3.3.2 Gradle 4.10.1 插件 3.3.2

我遇到了同样的问题，并通过执行以下操作解决了它:

转到 Project Non-Source Files 并打开 .idea libraries 文件夹 从此文件夹中删除所有数据绑定(bind)依赖项。

重建您的应用，应该没问题!
