Adding a profile for a custom language breaks other projects (with a NullPointerException within Sonar)

[petr.h...@iongroup.com]

Hello.

I created a custom Sonar plugin that adds a new language, new rules for that language a sensor for that language.

The project that I created afterwards that uses that plugin works fine as a multilanguage project, with both the new language and Java.

However, other projects, whether created before or after that, fail.

When I attempt to run "mvn sonar:sonar" on them, the following error results:

[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.4.0.905:sonar (default-cli) on project SampleProjectSonar2: Unable to load component class org.sonar.scanner.report.MetadataPublisher: Unable to load component class org.sonar.scanner.rule.ModuleQProfiles: E

When I go in Sonar web server log, it shows:

018.01.09 11:45:48 ERROR web[AWDByNoDzJDcGU53AAFe][o.s.s.w.WebServiceEngine] Fail to process request http://localhost:9000/api/qualityprofiles/search.protobuf?projectKey=java.sk.hudecekpetr%3ASampleProjectSonar2

No other logs show anything abnormal.

The new project doesn't show the quality profile for the new language in its Quality Profiles, its quality profiles can no longer be changed (assigning new profiles to it seems to work, but they never show up on the project screen) and the page "Administration->Quality Profiles" for those projects is empty  and the line "Failed to load resource: the server responded with a status of 500 ()" shows up in console log.

Do you know what causes this and how can I avoid it?

Best regards,

Petr

Hi Petr,

Could you please tell use which version of SonarQube you're using ?

Could you also please return the result of <YOUR_SONARQUBE_SERVER>/api/qualityprofiles/search?language=<YOUR_NEW_LANGUAGE> ?

Thanks.

Regards,

Hello Julien

The SonarQube version is 6.7.0.33306.

The API call you described returns this:

{
   "profiles":[
      {
         "key":"AWBqxsxep-FMzANyV-n-",
         "name":"Robot Profile Test",
         "language":"robot",
         "languageName":"Robot Framework DSL",
         "isInherited":false,
         "isDefault":false,
         "activeRuleCount":13,
         "activeDeprecatedRuleCount":0,
         "projectCount":1,
         "rulesUpdatedAt":"2017-12-22T14:04:40+0000",
         "lastUsed":"2018-01-09T11:46:48+0100",
         "userUpdatedAt":"2017-12-22T15:04:40+0100",
         "organization":"default-organization",
         "isBuiltIn":false,
         "actions":{
            "edit":true,
            "setAsDefault":true,
            "copy":true
         }
      }
   ],
   "actions":{
      "create":true
   }
}

Thank you very much for looking at this.

Best regards,

Bump.

If somebody has an idea of what I could try to bypass this error, I would be grateful. Is it possible that I forgot some initialization for the new language or something?

Best regards,

Petr

Hi Petr,

Sorry for the delai replying you, I think I've found the issue : there's no default quality profile for your new language. 

It's most probably because you've not defined a built-in one. You can use this API define one, and see how it's used in the plugin used in our integration test.

I hope it will fix your issue.

Regards

And in fact a ticket already exists to properly fail in your case : https://jira.sonarsource.com/browse/SONAR-10283.

[petr.h...@iongroup.com]

Hello Julien.

Thank you! That looks like my issue, yep. In the meantime, I have bypassed it by adding the rules to the 'java' language but applying them to files with the '.robot' extension. Inelegant, but it worked. 

Best regards,

Petr

Hi Petr,

I'm happy that you've solved your issue. I would have recommend you to provide a built-in quality profile in your plugin in order to fix this issue, but it's up to you !
