Sonar-Scanner执行扫描时报错

转载自：https://blog.csdn.net/qq_33912215/article/details/88711526

问题：

用Sonar-Scanner在远端执行扫描时，遇到如下一个报错：

ERROR: Error during SonarQube Scanner execution
ERROR: Failed to upload report - An error has occurred. Please contact your administrator

上传扫描结果失败。

定位日志：

查看sonar安装目录下的logs中的web.log，里面有如下报错信息

问题出在这里

com.mysql.jdbc.PacketTooBigException: Packet for query is too large (18307204 > 16777216). You can change this value on the server by setting the max_allowed_packet' variable.

是说向MySQL数据库中写数据的时候超过了单次最大数据量，可通过修改MySQL中max_allowed_packet参数进行解决。

解决步骤：
1、查看MySQL数据库的配置文件mysql.cnf，里面有配置（或命令show VARIABLES like '%max_allowed_packet%';）
max_allowed_packet     = 16M
2、修改成

max_allowed_packet     = 64M
3、然后重启MySQL容器，通过命令查看如下

show VARIABLES like '%max_allowed_packet%';

4、然后再重启sonar容器，一定要重启
5、重新执行sonar-scanner，可成功上传sonar report
6、等待sonar-server执行完分析后，即可在sonar web中查看报告。
