SonarCloud | Advanced setup | Analysis parameters

Analysis parameters

Most project analysis settings can be configured in three different places: in the UI, in a configuration file, or on the command line. In most cases, 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.

Setting configuration in the SonarCloud UI

Many analysis parameters can be configured in the SonarCloud UI itself. These can be found under Your Organization > Your Project > Administration > General Settings.

Setting configuration in a file

Analysis parameters can also be set in a configuration file within your project. The file used depends on your setup:

Maven Java project: pom.xml
Gradle Java project: build.gradle
Other CI-based analysis: sonar-project.properties
Automatic analysis: .sonarcloud.properties

Any setting made in a configuration file will override settings made in the UI.

Setting configuration on the command line

For CI-based analysis (not automatic analysis), parameters can also be set on the command line using the -D option indicator when launching an analysis. This can be done with the standalone command-line tool sonar-scanner, as well as with any of the build-tool-specific variants like SonarScanner for Maven and SonarScanner for Gradle.

Settings stored in database

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 database.

Most of the property keys shown in the UI 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 the documentation on Test coverage. For language-specific parameters related to external issue reports, see the page about External analyzer reports.

If you are looking for information about the SonarCloudPrepare task, see instead the documentation for the SonarCloud Extension for Azure DevOps.

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 SonarCloud server. The corresponding SonarCloud user must have the Execute Analysis permission on the project.

Notes: Replaces sonar.login and sonar.password properties which are deprecated.

Environment variable: SONAR_TOKEN (not supported by SonarScaner 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 of the SonarCloud server. Must be defined as https://sonarcloud.io.

Environment variable: SONAR_HOST_URL

For SonarScanners CLI from v6.0, SonarScanner for Maven (from v5.0), Gradle (from v6.0), .NET from v7.0, NPM from v4.0, and Python: https://sonarcloud.io
Otherwise: http://localhost:9000

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

sonar.organization The key of the organization to which the project belongs

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

Name of the project that will be displayed on the web interface.

Notes:

Is set in the UI if the project is manually created in SonarCloud (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. It should be set for long-lived branch analysis 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 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

Analysis scope

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>.minimumLines Is 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.branch.target`	The name of the target branch of the branch to be analyzed.

Pull request analysis

The following parameters relate to Pull request analysis and are only required for manual projects. For detailed information on their use, see Pull request analysis.

Property key Description Default

Property key	Description	Default
`sonar.pullrequest.key`	This property is the unique identifier of your Pull Request. Must correspond to the key of the Pull Request in your DevOps platform. Example: `sonar.pullrequest.key=5`
`sonar.pullrequest.branch`	This property is the name of the branch that contains the changes to be merged. Example: `sonar.pullrequest.branch=feature/my-new-feature`

sonar.pullrequest.key

This property is the unique identifier of your Pull Request. Must correspond to the key of the Pull Request in your DevOps platform.

Example: sonar.pullrequest.key=5

sonar.pullrequest.branch

This property is the name of the branch that contains the changes to be merged.

Example: sonar.pullrequest.branch=feature/my-new-feature

sonar.pullrequest.base

The branch into which the pull request will be merged (target branch).

Example: sonar.pullrequest.base=main

main branch

Other parameters

Property key	Description	Default
`sonar.scm.revision`	Overrides the revision, for instance, the Git `sha1`, displayed in analysis results. Note: May be provided by the CI environment or guessed from the checked-out sources.
`sonar.buildString`	The string passed with this property will be stored with the analysis and available in the results of `api/project_analyses/search`, thus allowing you to later identify a specific analysis and obtain its key for use with `api/project_analyses/set_baseline` on the SPECIFIC_ANALYSIS type.
`sonar.sourceEncoding`	Encoding of the source files. For example, `UTF-8`, `MacRoman`, `Shift_JIS`. The list of available encodings depends on your JVM. Default from build: Maven Gradle	The system encoding
`sonar.working.directory`	Path to the working directory used by the Sonar scanner during a project analysis to store temporary data. This property is not compatible with the SonarScanner for .NET.

Default from build: Maven Gradle	`.sonar`
`sonar.scm.forceReloadAll`	By default, blame information is only retrieved for changed files. Set this property to `true` to load blame information for all files, which may significantly increase analysis duration. This can be useful if you feel that some SCM data is outdated but SonarCloud does not get the latest information from the SCM engine and this analysis parameter should not be a permanent part of your analysis configuration.	`false`
`sonar.analysis.<key>=<value>`	This property stub allows you to insert custom key/value pairs into the analysis context, which will also be passed forward to webhooks. Example: `sonar.analysis.buildNumber=12345` Note: Depending on the environment, using this property in the command line may not work.
`sonar.userHome`	The base directory for various locations, such as the user cache. It must be located inside the user home directory. Environment variable: `SONAR_USER_HOME`	`~/.sonar`
`sonar.scanner.javaOpts`	Since SonarScanner CLI 6.0.0, the scanner engine will be started as a separate Java process. This property is used to pass arguments to the JVM running the forked scanner engine process. Can be used only with the SonarScanner CLI (from v6.0), SonarScanner for Maven (from v5.0), Gradle (from v6.0) and NPM (from v4.0). Examples: `SONAR_SCANNER_JAVA_OPTS=”-Xmx4g"` Or `SONAR_SCANNER_JAVA_OPTS=”-Xmx512m”` Environment variable: `SONAR_SCANNER_JAVA_OPTS`

Deprecated parameters

These parameters are listed for completeness, but are deprecated and should not be used in new analyses. They will be removed in the future. A user warning appears on the project interface if you activate this parameter.

sonar.login
sonar.password
sonar.projectDate

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

Property key	Description
`sonar.scanner.os`	The operating system of the machine hosting the SonarScanner. Default: the autodetected value Environment variable: `SONAR_SCANNER_OS` Not supported by the SonarScanner for .NET. Possible values: `windows`, `linux`, `macos`, `alpine`.
`sonar.scanner.arch`	The CPU architecture type. Environment variable: `SONAR_SCANNER_ARCH` Not supported by the SonarScanner for .NET. Default: the autodetected value Possible values: `x64`, `aarch64`.
`sonar.scanner.skipJreProvisioning`	Defines whether the JRE auto-detection is disabled (`true`) or not (`false`). Environment variable: `SONAR_SCANNER_SKIP_JRE_PROVISIONING` Not supported by the SonarScanner for .NET. Default: `false`
`sonar.scanner.javaExePath`	If defined, the SonarScanner will be run with this JRE. Environment variable: `SONAR_SCANNER_JAVA_EXE_PATH` Not supported by the SonarScanner for .NET. Default: The provisioned JRE, or use java from your PATH if `sonar.scanner.skipJreProvisioning=true`.
