如何在Windows命令行中生成用于Android Studio密钥库签名的.jpk签名文件？

Question

我正尝试在Android Studio中生成密钥库路径，如何找到java.io文件？我在Windows命令行中阅读并实现了一个解决方案：How can I create a keystore?。然后，我在执行解决方案后收到一个错误。我以管理员身份运行操作系统。

我了解到java.io是通用的。我在PC上搜索java.io文件，但没有找到。我了解到，这些问题中的许多都可以通过切换到Linux操作系统来避免。

预期的结果是.jpk密钥库签名文件。实际的结果是一个java.io.FileNotFoundException: my-release-key.keystore (访问被拒绝)错误。

要从命令行生成密钥库文件，必须以管理员身份运行命令行。这是通过在搜索栏中键入cmd，然后右键单击命令提示符应用程序，然后选择以管理员身份运行来实现的。https://www.howtogeek.com/howto/windows-vista/enable-the-hidden-administrator-account-on-windows-vista/按照How can I create a keystore?中概述的说明进行操作
