在这里你可以解决这个问题，你需要添加productFlavors的名称flavorDimension，并需要定义维度，参见下面的示例，更多信息请参阅https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html

flavorDimensions 'yourAppName' //here defined dimensions
productFlavors {
    production {
        dimension 'yourAppName' //you just need to add this line
        //here you no need to write applicationIdSuffix because by default it will point to your app package which is also available inside manifest.xml file.

    }

    staging {
        dimension 'yourAppName' //added here also
        applicationIdSuffix ".staging"//(.staging) will be added after your default package name.
        //or you can also use applicationId="your_package_name.staging" instead of applicationIdSuffix but remember if you are using applicationId then You have to mention full package name.
        //versionNameSuffix "-staging"

    }

    develop {
        dimension 'yourAppName' //add here too
        applicationIdSuffix ".develop"
        //versionNameSuffix "-develop"

    }

如果你不想用尺寸，你应该用这条线

android { 
compileSdkVersion 24

...
flavorDimensions "default"
...
}

但是如果你想使用维度，你应该先声明你的维度名，然后再使用这个名称 这个例子来自文档:

android {
...
buildTypes {
debug {...}
release {...}
}

  // Specifies the flavor dimensions you want to use. The order in which you
  // list each dimension determines its priority, from highest to lowest,
  // when Gradle merges variant sources and configurations. You must assign
  // each product flavor you configure to one of the flavor dimensions.
  flavorDimensions "api", "mode"

  productFlavors {
    demo {
  // Assigns this product flavor to the "mode" flavor dimension.
  dimension "mode"
  ...
}

full {
  dimension "mode"
  ...
}

// Configurations in the "api" product flavors override those in "mode"
// flavors and the defaultConfig block. Gradle determines the priority
// between flavor dimensions based on the order in which they appear next
// to the flavorDimensions property above--the first dimension has a higher
// priority than the second, and so on.
minApi24 {
  dimension "api"
  minSdkVersion 24
  // To ensure the target device receives the version of the app with
  // the highest compatible API level, assign version codes in increasing
  // value with API level. To learn more about assigning version codes to
  // support app updates and uploading to Google Play, read Multiple APK Support
  versionCode 30000 + android.defaultConfig.versionCode
  versionNameSuffix "-minApi24"
  ...
}

minApi23 {
  dimension "api"
  minSdkVersion 23
  versionCode 20000  + android.defaultConfig.versionCode
  versionNameSuffix "-minApi23"
  ...
}

minApi21 {
  dimension "api"
  minSdkVersion 21
  versionCode 10000  + android.defaultConfig.versionCode
  versionNameSuffix "-minApi21"
  ...
    }
  }
}
...

经过尝试和仔细阅读，我自己解决了。 解决方案是在build.gradle中添加以下行。

flavorDimensions“versionCode”

android { 
       compileSdkVersion 24
       .....
       flavorDimensions "versionCode"
} 

在KotlinDSL中，你可以这样使用:

flavorDimensions ("PlaceApp")
productFlavors {
    create("tapsi") {
        setDimension("PlaceApp")
        buildConfigField("String", "API_BASE_URL", "https://xxx/x/x/")
    }

}

在这里你可以解决这个问题，你需要添加productFlavors的名称flavorDimension，并需要定义维度，参见下面的示例，更多信息请参阅https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html

flavorDimensions 'yourAppName' //here defined dimensions
productFlavors {
    production {
        dimension 'yourAppName' //you just need to add this line
        //here you no need to write applicationIdSuffix because by default it will point to your app package which is also available inside manifest.xml file.

    }

    staging {
        dimension 'yourAppName' //added here also
        applicationIdSuffix ".staging"//(.staging) will be added after your default package name.
        //or you can also use applicationId="your_package_name.staging" instead of applicationIdSuffix but remember if you are using applicationId then You have to mention full package name.
        //versionNameSuffix "-staging"

    }

    develop {
        dimension 'yourAppName' //add here too
        applicationIdSuffix ".develop"
        //versionNameSuffix "-develop"

    }

如果您真的不需要这种机制，只需在构建中指定一个随机的风味维度。Gradle或build.gradle.kts:

android { 
    ...
    flavorDimensions("default")
    ...
}
