执行flutter build aar后报错：

FAILURE: Build failed with an exception.* Where: Initialization script '/Users/temp/Documents/flutter/packages/flutter_tools/gradle/aar_init_script.gradle' line: 19* What went wrong: Android property not found.* Try: Run with --stacktrace option to get the stack trace.

【记录一个flutter打包aar异常问题】问题定位flutter目录下aar_init_script.gradle文件，插入throw代码段，即可显示哪里出错。

if (!project.hasProperty("android")) { throw new GradleException(project.toString()) throw new GradleException("Android property not found.") }

重新执行build操作

FAILURE: Build failed with an exception.* Where: Initialization script '/Users/temp/Documents/flutter/packages/flutter_tools/gradle/aar_init_script.gradle' line: 19* What went wrong: project ':url_launcher_macos'* Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

显示url_launcher_macos出错，到flutter目录下隐藏文件.pub-cache内的hosted目录下

将pub.dartlang.org与pub.flutter-io.cn文件夹目录下的url_launcher_macos相关缓存都删除了，重新执行build aar操作，打包成功。
