findbug 3.4.4 failed to work with sonarqube 5.6

[stanle...@servicemax.com]

hello all

We had sonar scan for a java project, which is organized by maven and there are multiple modules.

we once used sonarqube 5.4 and seems findbug 3.1, at that time. 

The scan works well though we didn't compile the source code.

But we can see warning like this 

22:22:24 22:23:04.877 [main] WARN  o.s.plugins.findbugs.FindbugsSensor - Findbugs needs sources to be compiled. Please build project before executing sonar or check the location of compiled classes to make it possible for Findbugs to analyse your project.
22:22:24 INFO: Sensor org.sonar.plugins.findbugs.FindbugsSensor (done) | time=10ms

Recently we upgraded sonarqube to 5.6 and findbug to 3.4.3, and then it failed to work,  the scan kept failing at findbug plugin with blow errors

I tried to google it, someone mentiond we can add properties like 

"sonar.binaries=prj1/**/target/classes/" etc but it seems didn't work for me.

Here is my original properties file

sonar.projectKey=test

sonar.projectName=test (Java Code)

sonar.projectVersion=${git_branch}_${git_id}

sonar.sourceEncoding=UTF-8

sonar.login=admin

sonar.password=password

sonar.language=java

sonar.profile=JAVA

sonar.java.libraries=proj/**/*.jar

sonar.sources= proj

sonar.exclusions= proj/test_suite/**/*.java, proj/**/src/test/**, proj/testutils/**/*.java, proj/polyglot.ruby/src/main/resources/**/*.java

sonar.jacoco.reportMissing.force.zero=true

sonar.dependencyCheck.reportPath=dependency-check-report.xml

Any suggestion to fix the issue?

Thanks in advance.

Stanley

Hi Stanley,

Since FindBugs analyzes bytecode and only bytecode, it has always been required for successful FindBugs analysis. Now that's more obvious. :-)

Regarding your properties file, I don't actually see a property that points to your binaries...?

Yes, the post properties file doesn't have it.

I tried to compile the project and add property like "sonar.binaries=prj1/**/target/classes/" etc but it doesn't work for me.

I still see the error.

I didn't find a workable solution yet,  so I am wondering what could be the correct way to make it work?

Regards,

Stanley

Hi Stanley,

Try using `sonar.java.binaries` (I should have mentioned that before. If that doesn't work, take a look at the plugin's issues. This sounds kinda familiar.
