Gradle sync失败：无法在android studio

Question

我是android编程的新手，当我尝试构建我的第一个项目时，我收到以下错误 -

  

Gradle sync失败：无法在根项目＆＃39; MyApplication＆＃39;上找到参数[build_ed74sxwq3zd69j7x0p9x4y5fb $ _run_closure3 @ 3d54d64f]的方法android（）。类型为org.gradle.api.Project。

＆＃13;

＆＃13;

// 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:2.3.0'

        // 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
}

android {
    compileSdkVersion 19
    buildToolsVersion '25.0.2'
    dexOptions {
        incremental true
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_6
        targetCompatibility JavaVersion.VERSION_1_6
    }
}
dependencies {compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'

＆＃13;

＆＃13;

＆＃13;

app / build / gradle文件是 -

＆＃13;

＆＃13;

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.surabhi.myapplication"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        externalNativeBuild {
            cmake {
                cppFlags "-std=c++11"
            }
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    externalNativeBuild {
        cmake {
            path "CMakeLists.txt"
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'

Answer 1

您使用的是错误的 build.gradle文件。

您无法在顶级文件中定义 android块。

您

中有删除此部分

android {
    compileSdkVersion 19
    buildToolsVersion '25.0.2'
    dexOptions {
        incremental true
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_6
        targetCompatibility JavaVersion.VERSION_1_6
    }
}
dependencies {compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'

Answer 2

我在android studio 2.3.3中遇到了同样的问题，我错误的是我的依赖项是错误的build.gradle（这是错误的）

我们需要的build.gradle是带有android选项的那个，如下面的`apply plugin：'com.android.application'

android {     compileSdkVersion 23     buildToolsVersion '23 .0.0'

defaultConfig {
    applicationId "com.movas.mservice12"
    minSdkVersion 9
    targetSdkVersion 23
    versionCode 11
    versionName "2.0"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
lintOptions {
    abortOnError false
}
dexOptions {
   // incremental = true
    preDexLibraries = false
    javaMaxHeapSize "4g" // 2g should be also OK
}

}` 您可以在android花括号内添加dexOptions。

当我将它添加到项目级别的 gradle 文件时，我遇到了同样的错误。将其移至应用级 gradle 文件，您应该会好起来。
