Answer 1

The Exception message is clear about the problem, but not about the solution, which is: at the same place where you defined the sonar.sources property, add a sonar.binaries property that points to the location of the compiled code. For example, in a maven project you would typically have sonar.binaries=target/classes.

Answer 2

Include the below lines in the jenkins job configuration under execute SonarQube Scanner:

sonar.java.binaries=${workspace}/target/classes/

sonar.binaries=${workspace}/target/classes/
