java.lang.ClassNotFoundException

tip

Update "latest" to Java 8 on DockerHub.

tip

This might be caused by and outdated version of Java, SonarQube now uses Java 8 as default. You might upgrade java or use an older version of SonarQube.

tip

You're using an older version of java with classes compiled for java7

tip

If you're using intellij plugin of sonarqube, you might have to set the JAVA_HOME ambient variable manually.

You have a different solution? A short tip here would help you and many other users who saw this issue last week.
