Android Studio/Kotlin : Gradle error - cannot find compile() method for arguments [com. android.support:recyclerview-v7:$support_version]

Question

我使用的是 Android Studio 3.0 Canary 6。我在处理 build.gradle(项目)文件时遇到了一些问题。

build.gradle 文件如下:

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

    buildscript {
        ext.kotlin_version = '1.1.3-2'
        ext.support_version = '26.0.1'
        repositories {
            google()
            jcenter()
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:3.0.0-alpha6'
            classpath "org.jetbrains.kotlin:kotlin-gradle-
                plugin:$kotlin_version"
            compile "com.android.support:appcompat-v7:$support_version"
            compile "com.android.support:recyclerview-v7:$support_version"

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

    allprojects {
        repositories {
            google()
            jcenter()
            mavenCentral()
        }
    }

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

我得到的错误是:

Error:Error:line (13)Could not find method compile() for arguments [com.android.support:appcompat-v7:26.0.1] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler. Please install the Android Support Repository from the Android SDK Manager. Open Android SDK Manager.

请帮我解决这个错误。

从顶级 build.gradle 中删除 compile 依赖项，并将其放入您的应用程序级别 build.gradle dependencies，在项目 View 的 app/src 下可用。

dependencies {
    compile "com.android.support:appcompat-v7:26.0.1"
    compile "com.android.support:recyclerview-v7:26.0.1"
}

应用级依赖项(主要以编译开头)应放在应用级 build.gradle 文件下，而不是顶层 build.gradle 下。

实际上，build.gradle文件是用Groovy语言编写的，compile是一个方法调用。在 Groovy 中，我们可以 leave the parenthesis for top-level expressions .这就是为什么您会收到如下错误:

Could not find method complie()
