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

Answer 1

It works for me after defining :

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

seen in :

https://github.com/SonarQubeCommunity/sonar-findbugs/issues/49

Answer 2

We had the same issue for some projects (mainly Play Framework projects). I reverted the FindBugs plugin in SonarQube from version 3.4.3 to 3.3 (that I used on SonarQube 5.5) and then the analysis worked again.

Answer 3

My working configuration for SonarQube 6.2 with Maven-Multi-Module project

Parent

-- Module1

-- Module2

sonar.projectKey=projectKey
sonar.projectName=Project Name
sonar.projectVersion=1.0

sonar.modules=Module1,Module2

sonar.sources=src
sonar.sourceEncoding=UTF-8
sonar.language=java
