bug日记-缺少licences

报错信息

编译打包报错：Android SDK packages as some licences have not been accepted

报错信息如下
Failed to install the following Android SDK packages as some licences have not been accepted.
     build-tools;28.0.2 Android SDK Build-Tools 28.0.2
  To build this project, accept the SDK license agreements and install the missing components using the Android Studio SDK Manager.
  Alternatively, to transfer the license agreements from one workstation to another, see http://d.android.com/r/studio-ui/export-licenses.html

分析

明显缺少 build-tools;28.0.2 的licenses

升级 licenses

• 首先这肯定是 sdk 包里缺少对应 licenses，命令如下

sdkmanager --update && yes | sdkmanager --licenses

• sdkmanager 命令路径在 sdk 安装路径的tools/bin 下
• sdkmanager 官方介绍

总结

• 首先sdkmanager 等命令行工具在 sdk 的tools/bin
• 使用 sdkmanager 升级命令获取 licenses
