Android Studio 抛出 "No signature of method"错误，指向 build.gradle :app

Question

尝试通过 Android Studio 运行 Kotlin 应用程序后出现此错误:

A problem occurred evaluating project ':app'.
> No signature of method: build_4blexxmb1pl0fsds689m8rkwz.android() is applicable for argument types: (build_4blexxmb1pl0fsds689m8rkwz$_run_closure1) values: [build_4blexxmb1pl0fsds689m8rkwz$_run_closure1@220b09f3]

错误将我指向 build.gradle:app 的这一部分文件(特别是带有 android { 的行):

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    buildFeatures {
        viewBinding = true

        defaultConfig {
            applicationId "com.example.bitfighter"
            minSdkVersion 19
            targetSdkVersion 30
            versionCode 1
            versionName "1.0"

            testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        }

        buildReleases {
            viewBinding = true
        }

此错误消息是什么意思，我可以更改什么来解决问题？

尝试像这样构造代码

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.example.bitfighter"
        minSdkVersion 19
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildFeatures {
        viewBinding = true
    }

defaultConfig 应该始终只在 android 中。子句而不是在 buildFeatures 中。除此之外，当您已经添加了 buildFeatures 子句时，您不需要 buildReleases 子句。
