Solution 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.

Solution 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/

Solution 3

The issue is pretty clear:

Caused by: org.sonar.api.utils.SonarException: Findbugs needs sources to be compiled. Please build project before executing sonar and check the location of compiled classes.

Indeed FindBugs needs bytecode to look for violations.

we are using ant to build project and compiled classes are in bin folder do I need to put some extra tags in build.xml to make it work. Please guide me. Thanks

[Amit Kumar]

we are using sonar version 2.11 and jdk version as 1.6.0_29. We are using custom quality rule including PMD, checkstyle and findbugs. I upload this file in sonar and link it to particular project.

[Amit Kumar]

Can anybody help me out ??

@AmitKumar, I guess you haven't correctly set the value of the 'sonar.binaries' property

[yvolk]

Thank you, I changed sonar.binaries to bin/classes (in my case, for Android) and it worked!
