SonarQube Scanner execution execution Error --- Failed to upload report - 500: An error has occurred

問題緣由：mysql參數設置問題

檢查mysql參數：

mysql> SHOW VARIABLES LIKE 'max_allowed_packet';

修改/etc/my.cnf文件：

[mysqld]

max_allowed_packet = 50M

重啓mysql服務：

[root@sonar-test]# service mysql restart

重啓sonar服務

[sonar@sonar-test]$ sonar.sh restart
