Analysis parameters

On this page

Project analysis settings can be configured in multiple places. Each plugin and language analyzer adds its own properties which can be defined in the SonarQube UI; these properties can also be defined as analysis parameters, however, the descriptions of those properties and the best place to set them is in the UI when possible. Only parameters set through the UI are reusable for subsequent analysis and there is a structure to the way parameters are read by the scanner.

Here is the hierarchy in order of precedence:

Diagram showing settings hierarchy.
  1. Global properties: Apply to all projects. Defined in the UI in Administration > Configuration > General Settings
  2. Project properties: Apply to one project only. At project level, defined in the UI in Project Settings > General Settings
  3. Project analysis parameters: Defined in a project analysis configuration file or scanner configuration file
  4. Analysis / Command line parameters: Defined when launching an analysis with -D on the command line

Note that only parameters set through the UI are stored in the database. For example, if you override the sonar.exclusions parameter via the command line for a specific project, it will not be stored in the database. Subsequent analyses, or analyses in SonarLint with connected mode, would still be executed with the exclusions defined in the UI and therefore stored in the DB.

Most of the property keys shown in the interface at both global and project levels can also be set as analysis parameters, but the parameters listed below can only be set at analysis time.

For language-specific parameters related to test coverage and execution, see Test coverage. For language-specific parameters related to external issue reports, see External issues. And to learn more about controlling the scope of your analysis, see the page on Analysis scope.  

Mandatory parameters

This section lists analysis parameters (sonar properties) that, during a project analysis, cannot be set in the UI and are mandatory. It means that they must be set on the CI/CD host. The following default values are indicated for a parameter when applicable:

  • Default from build: It indicates from which build system(s) the scanner can read a default value for the sonar property. The build property used as the default value is not indicated: see the corresponding scanner section for more information.
  • Default: This value applies if the property was neither defined on the CI/CD host nor in the UI. 

In addition, if the analysis parameter can be set through an environment variable, the variable name is indicated.

Authentication to the server

Property key

Description

sonar.token

Token used by the scanner to authenticate to the SonarQube Server. A token can be specific to a project (allows you to run analyses on the specific project) or global (allows you to run analyses on any project). The corresponding SonarQube user must have the Execute Analysis permission on the project or the Global Execute Analysis permission, respectively. 

Note: Replaces sonar.login and sonar.password properties that are deprecated.

Environment variable: SONAR_TOKEN (not supported by SonarScanner for .NET)

Recommendation: It is recommended not to write passwords or authentication tokens in files and not to pass them as parameters in the command line.

Server connection

Property key

Description

Default

sonar.host.url

The URL to your SonarQube Server. You must define this URL because the SonarScanners also work with SonarCloud which uses a different URL.

Environment variable: SONAR_HOST_URL

For SonarScanner CLI from v6.0, SonarScanner for Maven v5.0, Gradle v6.0, .NET from v7.0, and NPM from v4.0:  https://sonarcloud.io

Project identification

Property key

Description

sonar.projectKey

The project's unique key. Can include up to 400 characters. All letters, digits, dash, underscore, periods, and colons are accepted.

Default from build

  • Maven
  • Gradle

Optional Parameters

This section lists analysis parameters (sonar properties) that, during a project analysis, cannot be set in the UI (or, like the sonar.projectName, cannot be changed in the UI) and are optional. It means that they can only be set on the CI/CD host. The following default values are indicated for a parameter when applicable:

  • Default from build: It indicates from which build system(s) the scanner can read a default value for the sonar property. The build property used as the default value is not indicated: see the corresponding scanner section for more information.
  • Default: This value applies if the property was neither defined on the CI/CD host nor in the UI. 

In addition, if the analysis parameter can be set through an environment variable, the variable name is indicated.

Project information

Property key

Description

sonar.projectName

The name of the project that will be displayed on the SonarQube UI.

Notes

  • Is set in the UI if the project is manually created in SonarQube (cannot be changed in the UI).
  • If passed in the command line, will only be read by the scanner if the command applies to the main branch. 
  • White space is allowed.

Default from build: Maven

sonar.projectVersion

The project version. Is mandatory in case you use the new code definition based on the previous version.

Note: Do not use your build number as the project version because:

  • This would overload the SonarQube database (Houskeeping would not apply to the analysis snapshots because they would be marked by the project version change event).
  • This would prevent a correct application of the new code definition based on the previous project version since the build version usually changes much more often than the project release version.

Default from build

  • Maven
  • Gradle
sonar.projectDescription

The project description.

Note: This property is not supported by the SonarScanner for .NET.

Default from build: Gradle

Analysis scope

Property key

Description

Default

sonar.sources

The analysis baseline for main source code (non-test code) in the project. 

*This property is not supported by the SonarScanner for .NET.

Possible values: Comma-separated paths to directories are included. An individual file in the list means that the file is included. A directory in the list means that all analyzable files and directories recursively below it are included. The path can be relative (to the sonar.projectBaseDir property) or absolute. Wildcards (*, ** and ?) are not allowed.

Default from build

  • Maven
  • Gradle
  • .NET
The value of the sonar.projectBaseDir property.
sonar.tests

The analysis baseline for test code in the project. 

*This property is not supported by the SonarScanner for .NET.

Possible values: See sonar.sources above.

Note: If this property is not defined, no code will be analyzed as test code as there is no default value.

Default from build

  • Maven
  • Gradle
  • .NET

sonar.projectBaseDir

The project’s base directory. Use this property when you need the analysis to take place in a directory other than the one from which it was started. For example, the analysis starts from jenkins/jobs/myjob/workspace but the files to be analyzed are in ftpdrop/cobol/project1

Possible values: The path may be relative (to the directory from which the analysis was started) or absolute. Specify not the source directory, but some ancestor of the source directory. The value specified here becomes the new "analysis directory", and other paths are then specified as though the analysis were starting from that specified value. 

Note: The analysis process will need Write permissions in this directory; it is where the sonar.working.directory will be created by default.

Default from build

  • Maven
  • Gradle
  • .NET
The directory from which the analysis was started.
sonar.scm.exclusions.disabled

For supported SCMs, defines whether files ignored by the SCM, e.g., files listed in .gitignore, will be excluded from the analysis or not. 

Possible values

  • true: exclusion disable
  • false: exclusion enabled
false
sonar.filesize.limit

Sets the limit in MB for files to be discarded from the analysis scope if the size is greater than specified.

Note: The sonar.javascript.maxFileSize property (default: 1000 KB) discards JavaScript and TypeScript files from the analysis scope if the file size is greater than specified (This parameter can be set in the UI).

20

Duplication check

Property key

Description

Default

sonar.cpd.<language>.minimumTokens

Is used for non-Java projects to define the duplication check rule: a piece of code is considered duplicated if sonar.cpd.<language>.minimumTokens identical tokens are found across at least sonar.cpd.<language>.minimumLines lines of code.

Note: For Java projects, a piece of code is considered duplicated when there is a series of at least 10 statements in a row, regardless of the number of tokens and lines. This threshold cannot be overridden.

100
sonar.cpd.<language>.minimumLinesIs used for non-Java projects to define the duplication check rule: see above.10

Analysis logging

Property key

Description

Default

sonar.log.level

Controls the quantity/level of logs produced during an analysis. 

Possible values: From least to most verbose: 

  • INFO
  • DEBUG
  • TRACE: like DEBUG with possible additional information output by plugins or libraries used by the scanner.
INFO
sonar.verbose

Possible values:

  • true: adds more details to the analysis logs by activating the DEBUG mode for the scanner.
  • false

Note: There is the potential for this setting to expose sensitive information such as passwords if they are stored as server-side environment variables.

false
sonar.scanner.metadataFilePathSets the location where the scanner writes the report-task.txt file containing among other things the ceTaskId.The value of sonar.working.directory.

Quality gate

Property key

Description

Default

sonar.qualitygate.wait
