Can not execute Findbugs Caused by: This project contains Java source files that are not compiled

Question

I am currently using the sonarqube server 5.6 with scanner 2.6.1 and I keep getting errors during analysis for a java project. It appears to complain about some java files not compiled in the binaries folder (there aren't any at all in the binaries folder). Once I add the -X parameter I get more exceptions (flagged as ignored), see below. any clues?

sonar-project.properties followed by logs

sonar.projectKey=myproj
sonar.projectName=myproj
sonar.projectVersion=1.1
sonar.branch=1.1
sonar.sources=./java
sonar.binaries=./deploy
sonar.log.level=DEBUG
sonar.verbose=false
sonar.sourceEncoding=UTF-8

execution without the -e param

with the -X parameter

then multiple exceptions DEBUG: Keep looking, ignoring exception com.puppycrawl.tools.checkstyle.api.CheckstyleException: Unable to find class for com.puppycrawl.tools.checkstyle.checks.sizes.WhitespaceAroundCheck

Answer 1

It works for me after defining :

sonar.java.binaries=[YOUR_BUILD_DIR] (target/classes)
