Answer 1

SonarQube Scanner 3.1.0.1141 (19:49:25.211 INFO: SonarQube Scanner 3.1.0.1141) is compatible with SonarQube 5.6+ (LTS) (read more here). You have SonarQube server 5.0.1 (19:49:25.610 INFO: SonarQube server 5.0.1) so those two tools are incompatible (class org/sonar/batch/bootstrapper/LogOutput$Level has been added in 5.2).

You can:

• use an older version of the scanner (download sonar-runner 2.4 - read about runner vs scanner)
• upgrade SonarQube server to at least 5.6
