Sonar Maven plugin (3.0.1, 3.0) intermittent build failures

Hi All,

With the latest Sonar Maven plugins (3.0 and 3.0.1) our builds sometimes fail with the following error message:

The problem does not occur with the 2.6 version. Based on some debugging this is a multithreading issue, because if the execution is slower the plugin works correctly. After going through the sources the changes done as part of this issue are partially responsible, because previously the POM files were not considered as a source to be analysed by default. Could you please look into it? Thank you.

Versions:

• Maven: 3.0.5, 3.3.3, 3.3.9
• Java: 1.8.0_60
• SonarQube: 4.3.3
• Sonar Maven Plugin: 3.0.1, 3.0

Hi!

Could you please provide the version of SonarQube (server) you are using?

Is there anything special in your Maven build that would explain why the file /opt/build-dir/WLC-SBDEV-JOB1/module1/pom.xml would be missing? In JIRA you talked about concurrency issue. Are you running Maven with parallel options enabled?

Hi,

Yes, the SonarQube version is 4.3.3 and there is nothing special about the project. The file is there, but for some reason Sonar treats it as a folder.

Regarding the Maven command we are running it single-threaded.

Best Regards,

Arpad

SonarQube 4.3.3 is no more supported. You should update to at least the LTS (4.5.6). If for some reason you can't then you should lock the version of the Maven plugin to an old version.

You should have a WARN log saying:

"With SonarQube prior to 4.5, it is recommended to use maven-sonar-plugin 2.6"

Is it not the case?

[Arpad Toman-Marton]

Hi,

Yes, it is the case and it works fine with 2.6. However, the newer plugins also do sometimes. Do you think this could be a server issue?

Arpad

[Julien HENRY]

I'm sorry but I don't see how it could work. SonarQube 4.3.3 was not supporting passing files to sonar.sources so it is expected that it fails on pom.xml.
