2. Solution 1

2.1 modify configuration file
You can edit my.cnf to modify it (my.ini under windows), in the [mysqld] section or the server configuration section of mysql.
max_allowed_packet = 20M 
If you can't find my.cnf, you can
mysql –help | grep my.cnf 
Go to find my.cnf file.
Under linux, the file is under / etc /.
2.2. Modify in mysql command line
Run in mysql command line
set global max_allowed_packet = 2*1024*1024*10 
Then exit the command line, restart the mysql service, and enter again.
show VARIABLES like '%max_allowed_packet%'; 
Check whether the max allowed packet is edited successfully

3. Scheme II

Modify profile

sonar.projectKey=xx:xxx
sonar.projectName=xxx
sonar.projectVersion=0.0.1-SNAPSHOT
sonar.sourceEncoding=UTF-8
sonar.sources=src/main/java/com/xxx/xxx ###Specifies the exact location of the file, reducing the size of the error file
sonar.java.binaries=target/classes
