执行失败任务 ':app:kaptGenerateStubsDebugKotlin'

Question

当我想要运行应用程序时，我得到以下构建输出：

Execution failed for task ':app:kaptGenerateStubsDebugKotlin'.
> Could not resolve all files for configuration ':app:kapt'.
   > Could not find com.android.databinding:compiler:4.2.1.

我已经在 Whosebug 上搜索过了，但没有帮助。我在这个问题上停留了 2 天，这让我抓狂：/ 我的项目 build.gradle 文件：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    ext.kotlin_version = "1.5.10"
    ext.version_navigation = "2.3.0"
    ext.version_core = "1.3.1"
    ext.version_constraint_layout = "2.0.0-rc1"
    ext.version_lifecycle_extensions = "2.2.0"
    ext.version_material = "1.2.0"

    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.2.1"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"


        // Navigation
        classpath "androidx.navigation:navigation-safe-args-gradle-plugin:$version_navigation"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}


allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
    }
}

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

我的模块build.gradle文件：

    kapt "com.android.databinding:compiler:4.2.1"

我希望你能帮助我。如果您需要有关我的项目的更多信息（例如片段文件或类似文件），请写信给我。

你不需要放

kapt "com.android.databinding:compiler:4.2.1"

只需要在 gradle 中启用数据绑定，而您做到了
