Android Studio 重复生成的文件
Posted
技术标签:
【中文标题】Android Studio 重复生成的文件【英文标题】：Android Studio duplicate generated files 【发布时间】：2020-02-10 09:36:52 【问题描述】：android Studio 不断创建生成的类，即使它们已经存在。
我猜这个问题与 NavigationArgs 有关，但它总是会产生一些重复错误。
现在解决我的问题的唯一方法是每次运行应用程序之前清理整个项目。
有谁知道如何解决这个问题，我怎么知道是哪个实现导致了这个错误？

【问题讨论】：
我也有同样的问题 我只是在切换风格时删除了生成的文件夹作为解决方法。我已向导航开发人员提交了有关此问题的错误。 【参考方案1】：选项 1：
请删除文件夹
点击 assembleDebug 后删除文件夹：
执行此命令后AssembleDebug你会得到你的错误。
选项 2：
按照以下说明解决。
项目级 build.gradle
使用
maven url "https://www.jitpack.io"
而不是
maven url "https://jitpack.io"
【讨论】：
没有解决问题，抱歉：/ 试试这个：选项 2 像魔术一样为我工作......但我删除了两个文件夹“.gradle”和“build”然后正常运行应用程序，它会自动重新生成文件夹，从而删除重复实例 您能否解释一下选项 2 是如何解决问题的？我得到同样的问题。选项 1 临时修复它，但在 2-3 次构建后它开始重新出现。 同样的问题，尝试了很多东西。没有布宜诺【参考方案2】：进入菜单并选择：Build -> Clean Project，完成后，Build -> Rebuild project
【讨论】：
【参考方案3】：如果点击 Build -> Clean project 或 Rebuild project 不能解决这个问题，应该有另一个问题导致构建失败。修复其他问题，重建可能会成功。
还要检查包中是否存在真实的BuildConfig文件，删除后重试。
