Answer 1

Original error: Could not find 'apksigner.jar' in ["C:\Users\admin\Downloads\commandlinetools-win-6858069_latest\cmdline-tools\bin\path-to-where-cmdline-tools-is\platform-tools\apksigner.jar"

它在错误中清楚地说明了缺少了什么。试着安装最新的构建工具

https://developer.android.com/studio/intro/update

Answer 2

如果您下载了命令行工具，但尚未解压“build”文件夹，则打开cmd，转到SDKManager所在的文件夹位置，然后运行以下命令：

//sdkmanager build-tools version number like following command

sdkmanager build-tools;31.0.0 

apksigner.jar位于build\version\lib文件夹中。

运行上述命令后，在环境变量中设置路径(在其中存在apksigner.jar )。

您可以从以下链接检查生成工具版本列表：https://developer.android.com/studio/releases/build-tools

或者只需在cmd中运行以下命令：

sdkmanager --list

Answer 3

解决办法：

• 在路径.JAR中检查/Android/sdk/build-tools/33.0.0/apksigner
• 我用的是33.0.0，这个版本对你来说可能不一样，但重点是位置
• 如果找不到.JAR，我会说请重新安装android-sdk。
• 因为修复大型android中的每个文件可能是一项繁琐的任务。重新安装可以轻松地修复问题。
