android - 无法在另一台 PC 上构建我的 android studio 项目，gradle 说“原因：路径可能不是 null 或空字符串。path='null'”

Question

我正在 Android Studio 3.5.2 中开发一些 android 应用程序。它工作正常，没有任何问题。

但是当我试图在另一台 PC 上构建它时它失败了。

摇篮 说： Cause: path may not be null or empty string. path='null'

详细错误信息：

PS 我阅读了这个错误堆栈跟踪，但我仍然无法解决问题，也无法理解其原因。

已解决：

我使用此命令找出原因： gradlew assembleDebug --info

首先我发现 gradle 无法编译，因为我的 JAVA_HOME 变量没有设置。此外，我安装了与我的 gradle 不兼容的 java 13，我还需要安装 java 11。

之后，我能够编译并运行我的项目。

查找我遇到这篇文章的异常

这通常发生在我们弄乱代码中的某些内容时，例如 id 或错误的导入，您可以使用

gradlew assembleDebug --info

编译代码并查看详细的错误日志。在那里你会发现你搞砸了。
