最新 Android Studio 更新 3.3.2 后未解决的 DataBinding 依赖关系

Question

在对 Android Studio 进行最新更新后，缺少 DataBinding 依赖项。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

这是我的应用 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

当我在 Android Studio 的 3.3.2 版本中进行 Gradle 更新时，我遇到了这个问题。但是在我看来，Android Studio 并没有为这次更新做好充分的准备。所以我将 gradle 的版本返回到 3.3.1，一切都恢复了。

glideVersion = '4.8.0'

gradle版本 = '3.3.1'

Answer 2

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：

转到项目非源文件并打开 .idea 库文件夹从此文件夹中删除所有数据绑定依赖项。

重新构建您的应用，应该没问题！

Answer 3

当您的代码中出现小错误时，问题就开始了（因为升级到 android x，R id 可能几乎没有变化）所以预处理器无法解释代码。并生成 classes 然后 class 名称猜测功能自 3.2.0 开始无法正常工作。

并导致错误：无法猜测 com.PackageName.ClassName。（如果您需要下面的堆栈跟踪）

问题出在 com.PackageName.ClassName 它猜测 com.PackageName 我相信它会搜索第一个大写字母并将其设为 class

所以解决方案是让包名以小写字母开头

我在这个帖子中找到了答案：只需将包名称更改为小写即可。

有效地进行重构：

错误是针对为布局生成的 classes。

让所有包都变成小写。
在每个数据绑定中 layout.xml
在变量中，
在类型属性中，
右击包名，
然后点击重命名。
选中两个复选框。点击确定。
单击“重构”按钮。

无法猜测包名的堆栈跟踪：

Answer 4

我遇到了同样的问题。我在这些步骤中修复了它。

1.在 build.gradle（应用级别）

添加 kotlin "KAPT" 插件

apply plugin: 'kotlin-kapt'

2。添加此依赖项并重建您的应用程序

implementation "androidx.lifecycle:lifecycle-extensions:2.2.0-rc02"
