SonarQube 6.7.4 incremental scan - sonarqube

We are evaluating how incremental Sonar static code analysis can be achieved. We usually do full code quality check and post the results on Sonarqube dashboard. The requirement is to run incremental scan on the modified changes from Git repository. My concern is results will be overwritten every time incremental scan is executed. Is there a way to resolve that issue? I need to have full report and also delta scan results (on every build) on Sonarqube project. Is it possible?

Narrow SonarQube analysis to single commit

SonarQube analysis in our project lasts arround 5 hours, because of large code base.
Is there any way to narrow SonarQube analysis to single commit, so that after push, sonarqube will analyse only that single commit, and form report, based on new code in this commit?
I expect a solution, that allow sonarqube to run analysis on single commit or any other solution, so analysis time will be shortened as much as possible

Can sonarqube gitlab plugin only scan changed files

I'm using gitlab-ci pipeline, it will run a new docker container with following commands:
mvn --batch-mode verify sonar:sonar
-Dsonar.analysis.mode=preview
-Dsonar.gitlab.project_id=$CI_PROJECT_ID
-Dsonar.gitlab.commit_sha=$CI_COMMIT_SHA
-Dsonar.gitlab.only_issue_from_commit_file=true
-Dsonar.gitlab.ref_name=$CI_COMMIT_REF_NAME
-Dsonar.host.url=xxx
-Dsonar.test.inclusions="/src/test/java/**/*.java"
-Dsonar.login=xxx
It becomes quite slow for my project, almost run for 20mins.
I found it will scan all files instead of only the commited files.
Is there anything wrong with my configurations?
In some past SonarQube versions we changed the preview mode to only scan changed files. But it has some drawback, like not being able to properly detect cross file issues.
In recent SonarQube versions, the preview mode is deprecated in favor of pull request analysis. But even this PR analysis feature is scanning all files, for the same reasons (cross file issues, coverage measures, duplication detections, ...).
We stopped trying to do partial analysis, and are instead trying to optimize full analysis duration. How big is your project? Is SonarQube analysis time long compared to your regular build (compile + tests)? If yes, then I suggest you report you case on the SonarSource community forum.

See history of Sonar analyses in SonarQube

I am triggering a Sonar analysis from Jenkins whenever a user commits any change to any branch of my project. In SonarQube I see the project analysis result, and quality gate status, for the most recently run analysis. It only shows the most recently run analysis for a given project.
How can I see a 'history' of previous analyses that were run prior? Specifically I would like to see the coverage from before and the where in the codebase specific 'critical' issues triggered a quality gate failure. Basically I want a historical snapshot of the 'project overview' page for each time the analysis is run. Since I am triggering the analysis from different branches I need to be able to differentiate an analysis of Branch A vs. a previous analysis of Branch B.
If you use SonarQube up to version 5.6: Use the Sonar Timeline Plugin, which allows you to add a graph to your dashboard.
If you use SonarQube version 6.5 or later (to be released in August 2017): Get feature rich history graphs out of the box (no plugin required)!
It looks like you have to make a custom dashboard and add a history widget. It looks like it shows you just the times the gate changed (which i guess is what I should have expected) for example the project I tested with only changed status 3 times so even though I asked for 10 columns it only showed 3.
This is on the Sonar homepage for your project, not the sonar widget in jenkins fyi

Coverage Reports on SonarQube Preview/Incremental analysis

We've recently set our Continuous Integration environment to do an incremental code analysis before a Merge Request on Git can be accepted. We already use the HTML issues report and the Build Breaker plugin. Everything works beautifully. The thing is, we're having some issues because the build is broken on < 85% code coverage. I didn't find any plugin to let the user know where the coverage dropped. Is there any way to show that comparison between the analisys that is recorded on my server and the one Jenkins is incrementally building ?
Thanks a lot!
Im using sonar4.5.4 and we use the Coverage on new code metric in our quality gate, in that metric we compare with the previous analysis

User specific sonar reports for same project

I have configured one project in sonar and integrated sonar with maven for build time analysis of the project.
After analysis, report is generated and uploaded to Sonar for browsing. But once another user compiles the same project their report overwrites mine.
Basically I want that one user's report on one project is not overwritten by report from other user. A user must be able to see their current violations independently. Is it possible in Sonar?
Sonar stores it's analysis on a daily basis, which explains why it's kind of pointless to run analysis several times in a day. Each analysis run will overwrite that day's existing results, which in turn spoils ongoing statistical analysis.
I would suggest running Sonar, from a dedicated build server like Jenkins (which has a Sonar plug-in). This daily analysis will populate the Sonar database and keep the project dashboard current. This architecture also enables you to keep the database credentials confidential.
Obviously developers would like to see the results of their bug fixing. For that I'd recommend running the Sonar Eclipse plug-in. The latest version will run the same Sonar analysis locally. Recent versions of Sonar also enable you to assign violations to developers for resolution.
This is not possible, last performed analysis will always be the one you browse in the interface. However, I guess what you need is the Issue Report Plugin which will enable analysis to store results locally, with the dry-run option.
This way your developers will be able to run an analysis on their code and see the violation delta without pushing the results.
You can do it by explicitly setting the below properties in pom.xml
<properties>
<sonar.projectKey>Test</sonar.projectKey>
<sonar.projectName>Test</sonar.projectName>
</properties>
Every user should set different projectKey and projectName, if you want that one user's report on one project is not overwritten by report from other user.
