未找到gradle dsl方法＆＃39; android（）＆＃39;错误（19 0）

Question

我收到此错误并尝试清理项目并重建它。但它没有用。
而且我也试图从gradle中删除一些代码，但仍无法正常工作。

请指教。
感谢。

错误：

这是Build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
//        classpath 'com.google.gms:google-services:1.3.0-beta1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        jcenter()
    }
}

android {
    compileSdkVersion 21
    buildToolsVersion '20.0.0'
}
dependencies {
}

这是来自app \ build.gradle

apply plugin: 'com.android.application'
//apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 21
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "me.kevingleason.pubnubchat"
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.pubnub:pubnub-android:3.7.4'
    compile 'com.google.android.gms:play-services:7.5.0'
}

Answer 1

尝试以下操作，看看是否有效。另外，为我提供你正在使用和构建工具版本的android studio版本。

的build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.1.2'

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

allprojects {
  repositories {
    jcenter()
  }
}

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

应用程序/的build.gradle

apply plugin: 'com.android.application'

android {
compileSdkVersion 21
buildToolsVersion '24.0.0' //replace with your buildtoolsversion here

defaultConfig {
    applicationId "me.kevingleason.pubnubchat"
    minSdkVersion 15
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    provided 'com.android.support:support-annotations:23.3.0'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:design:23.4.0'
    compile 'com.google.android.gms:play-services:9.0.2'
    compile 'com.android.support:support-v4:23.4.0'
    compile 'com.pubnub:pubnub-android:3.7.4' //erase if error is given and recompile
}

Answer 2

您的问题首先是外部dependencies中的第二个buil.gradle。这实际上是错误消息中的第19行。删除它（在第一个末尾）：

dependencies {
}

然后上面有一些NOTE评论说明：

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

因此，根据经验，请记住始终将您的依赖项放在app-module build.gradle中，而不是项目的依赖项。

希望您觉得这很有帮助。
