Gradle 生成apk ion ionic3项目时发生梯度生成错误

早上好devloper请在尝试从ionic3项目构建apk时，继续获取下面的错误

无法为com.android.build.gradle.LibraryExtension类型的对象获取未知属性“cdvCompileSdkVersion”

我的身材在下面

buildscript {
    repositories {
        maven {
            url "https://maven.google.com"
        }
        jcenter()
    }


    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0+'
    }
}

    apply plugin: 'com.android.library'

    dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    debugCompile project(path: ":CordovaLib", configuration: "debug")
    releaseCompile project(path: ":CordovaLib", configuration: "release")
}

    android {
    compileSdkVersion cdvCompileSdkVersion
    buildToolsVersion cdvBuildToolsVersion
    publishNonDefault true

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_6
        targetCompatibility JavaVersion.VERSION_1_6
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
            jniLibs.srcDirs = ['libs']
        }
    }
}

    if (file('build-extras.gradle').exists()) {
    apply from: 'build-extras.gradle'
}

下面是我的package.json，如果需要更多详细信息，我已经尝试删除build.gradle，但似乎没有帮助
