如何修复错误：没有此类属性：类的javaOutputs:com.android.build.gradle.internal.scope.VariantScopeImpl

嗨，我是Kotlin的新手，我想做单元测试。 因此，我添加了从该链接获得的配置：

以下是我补充的内容： 内建gradle

dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    /** Add junit5 plugin as a buildscript dependency**/
    classpath 'de.mannodermaus.gradle.plugins:android-junit5:1.0.0-M2'

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

这是我的应用程序build.gradle：

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

/**  Run the junit's plugin as part of the build**/
apply plugin: 'de.mannodermaus.android-junit5'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.tharwa.solid.tharwa"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

/**

 **/
junitPlatform {
    jupiterVersion '5.0.0-M3'
    platformVersion '1.0.0-M3'
}

    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

一旦我将项目与Gradle文件同步，我总是会出现以下错误：

Error:No such property: javaOuptuts for class: com.android.build.gradle.internal.scope.VariantScopeImpl

Gradle sync failed: No such property: javaOuptuts for class: com.android.build.gradle.internal.scope.VariantScopeImpl
            Consult IDE log for more details (Help | Show Log) (11s 191ms)

我有安卓3.0.1版本。 我已经搜索和尝试了一些东西，但它不适合我。 有人能帮忙吗。

我在工作室升级gradle时发生了一个错误。我进入了它使用的项目设置中，该版本升级失败。我把它降级回升级前使用的版本，它重新开始工作

你有什么解决办法吗？
