SonarQube Troubleshooting

Java heap space error or java.lang.OutOfMemoryError,

Increase the memory via the SONAR_SCANNER_OPTS environment variable:

export SONAR_SCANNER_OPTS="-Xmx512m"

On Windows environments, avoid the double-quotes, since they get misinterpreted and combine the two parameters into a single one.

set SONAR_SCANNER_OPTS=-Xmx512m

Unsupported major.minor version

Upgrade the version of Java being used for analysis or use one of the native package (that embed its own Java runtime). SonarQube 5.6+ requires Java 8.

**For versions prior to SonarQube 4.1, you can enable debug logging by adding the following to conf/logback.xml:**

conf/logback.xml

<appender-ref ref="CONSOLE"/>

<appender-ref ref="SONAR_FILE"/>

</logger>

Time out when running SonarQube analysis using LDAP

These both following parameters can be set in the <SonarQube home>/conf/wrapper.conf file to manage time out :

/conf/wrapper.conf

wrapper.java.additional.6=-Dcom.sun.jndi.ldap.connect.pool.prefsize=0

wrapper.java.additional.7=-Dcom.sun.jndi.ldap.connect.pool.timeout=3600000
