分析错误信息:
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.
得到以下结论:
构建当前的项目缺少下面的android sdk
所以下载这个sdk即可:
build-tools;28.0.2 Android SDK Build-Tools 28.0.2
解决办法:
使用android命令 列出sdk相关的列表，以便我们选择和自己项目匹配的SDK版本
android list sdk --all
输出如下所示：
从上图可以看出,Android SDK Build-Tools 28.0.2对应的序号是7,使用android update命令安装:
android update sdk -u -a -t 7
安装完成:
再次在app目录下,测试gradle clean命令,就执行成功了:
