Sonarqube scanner report upload error 500

Question

When every I create a new project with SonarQube project properties, I get this error:

My sonar-project.properties file is:

sonar.host.url=http : // sonarqube_server:9000
sonar.projectKey=sonar.org:projectname
sonar.projectName=WP_projectname
sonar.projectVersion=1.0
sonar.exclusions=bower_components/**,public_html/bower_components/**
sonar.sources=.

Answer 1

The problem often is that SonarQube generates a huge report and then tries to upload it in one shot, causing HTTP 500, because MySQL refuses to accept such a large request body.

The quick fix is to change the server config (my.ini file), to increase packed size (from default 4MB, to whatever is your report size):

[mysqld]
max_allowed_packet = 16M

per https://groups.google.com/forum/#!msg/sonarqube/c_DcwoN4qlg/wmnosoJkBAAJ

p.s.: you will also need to restart both MySQL and sonar services to apply changes.

Answer 2

I faced same issue with following error message visible in sonarqube-6.7.4/logs/web.log:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: The size of BLOB/TEXT data
inserted in one transaction is greater than 10% of redo log size.
Increase the redo log size using innodb_log_file_size.

Again, best option is to reduce report archives size excluding non relevant folders or files.

By the way, if you really have to tune MySQL for 30 MiB compressed reports, you may create /etc/mysql/conf.d/sonarqube.cnf on Debian-based Linux system with content:

# Work-around Sonarqube large report storage trouble
[mysqld]
innodb_log_file_size = 150994944
