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This might be caused by and outdated version of Java, SonarQube now uses Java 8 as default.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

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

tip

Update "latest" to Java 8 on DockerHub.

tip

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

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