当我在Android Studio 3.1.3中创建新项目时。总是得到此错误在项目'：app'中找不到任务'prepareReleaseUnitTestDependencies'

Question

成绩文件

在Android Studio 3.1.3中创建新项目时，这是gradle文件。但是，当将项目导入到另一台PC或从bitbucket或git克隆项目时，它可以完美运行。

apply plugin: 'com.android.application'
android
{
compileSdkVersion 28
defaultConfig {
    applicationId "com.example.murtuzanalawala.testdemo"
    minSdkVersion 14
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner 
  "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies
    {
       implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation 'com.android.support:appcompat-v7:28.0.0-beta01'
        implementation 'com.android.support.constraint:constraint-layout:1.1.2'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'com.android.support.test:runner:1.0.2'
        androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

}
