Once the SonarQube platform has been installed, you're ready to install an analyzer and begin creating projects. A project is created in the platform automatically on its first analysis. However, if you need to set some configuration on your project before its first analysis, you have the option of provisioning it.

Scope of Analysis: Types of Files and Data

SonarQube can perform analysis on 20+ different languages. The outcome of this analysis will be quality measures and issues (instances where coding rules were broken). However, what gets analyzed will vary depending on the language:

  • On all languages, "blame" data will automatically be imported from supported SCM providers. Git and SVN are supported automatically. Other providers require additional plugins.
  • On all languages, a static analysis of source code is performed (Java files, COBOL programs, etc.)
  • A static analysis of compiled code can be performed for certain languages (.class files in Java, .dll files in C#, etc.)
  • A dynamic analysis of code can be performed on certain languages.

Unrecognized files

By default, only files that are recognized by a language plugin are loaded into the project during analysis. For example if your SonarQube instance has the Java and JavaScript plugins on board, all .java and .js files will be loaded, but .xml files will be ignored. However, it is possible to import all text files in the analysis encoding in a project by setting Settings > Exclusions > Files > Import unknown files to true. 

During Analysis

During analysis, data is requested from the server, the files provided to the analysis are analyzed, and the resulting data is sent back to the server at the end in the form of a report, which is then analyzed asynchronously server-side.

Analysis reports are queued, and processed sequentially, so it is quite possible that for a brief period after your analysis log shows completion, the updated values are not visible in your SonarQube project. However, you will be able to tell what's going on because an icon will be added next to the project name. Mouse over it for more detail (and links if you're logged in with the proper permissions.)

The icon goes away once processing is complete, but if analysis report processing fails for some reason, the icon will change:

For more detail on analysis report processing, see Background Tasks.

Running Analysis

First, you should install the plugin(s) for the language(s) of the project to be analyzed, either by a direct download or through the update center.

Then, you need to choose an analysis method. The following are available:

Note that we do not recommend running an antivirus on the machine where a SonarQube analysis runs, it could result in unpredictable behavior. User?

If you are using and TravisCI, you can use the folllowing Travis Add-On to directly feed with the minimum of configuration:
