'app:bundleDebugJsAndAssets' as a task with that name already exists

Add productFlavor: productFlavors { Beta { manifestPlaceholders = [UMENG_CHANNEL:“Beta”] buildConfigField “String”, “CHANNEL”, “"Beta"” }

    Qianmi {
        manifestPlaceholders = [UMENG_CHANNEL:"WEB"]
        buildConfigField "String", "CHANNEL", "\"WEB\""
    }

}
