wifi_connect_demo.c无法编译？

neptune开发板，neptunt-hARMony-os1.1-iot-master源码，测试wifi_connect_demo.c时，无法编译。但是测试wifi_scan_demo.c这个样本时，编译通过，并且能够下载到开发板中，能够得到scan后的wifi地址，按照说明更改BUILD.gn后，添加wifi_cnnect_demo.c后，编译无法通过，提示报警“./../applications/sample/wifi-iot/app/wifi/wifi_connect_demo.c:39:28: fatal error: lwip/api_shell.h: No such file or directory”，这个问题如何解决？
下面是build.log 信息：

The variable "ohos_build_datetime" was set as a build argument
but never appeared in a declare_args() block in any buildfile.

To view all possible args, run "gn args --list "

The build continued as if that argument was unspecified.

Done. Made 78 targets from 63 files in 195ms
