当我尝试生成apk时，我收到以下错误。如何解决？

错误：任务执行失败'：app：transformClassesWithMultidexlistForDebug'。

  

java.io.IOException：错误的类路径：找不到文件“/ Users / gowthamichintha / Downloads / 20”

这是我的gradle控制台

请检查此json文件路径，如果可能，请更改json文件路径并尝试构建应用程序。

 Parsing json file: /Users/gowthamichintha/Downloads/20:03:2018 
 android/app/google-services.json

您正在使用已弃用的关键字来实现外部存储库。请按照以下步骤操作。

将google()个回复添加到project>build.gradle这样的

中 
allprojects {
    repositories {
        google() //this is for to download Google's repo like admob, playservices,maps firebase and all
        jcenter() 
    }
}

现在使用实施替换所有编译关键字<{1}} 

app>build.gradle

答案 2 :(得分：0)

您的项目位于无效命名的文件夹（20:03:2018 android）内。虽然在文件夹名称中使用冒号:可能对Unix有效，但它可能会导致其他应用程序出现问题。例如，在Gradle中（如this bug report中所示），冒号是一个保留的键字符，一个指定特定构建类型将应用于模块的分隔符。

我建议将项目文件夹重命名为Gradle-friendly，例如使用连字符和下划线，即：20-03-2018_android。请务必先关闭Android Studio，然后在下次打开Android Studio时手动打开该项目。
