– Lisa Quinlan-Rahman, Head of Digital
sonar-project.properties
Add a sonar-project.properties file to the same level as the .sln file
# must be unique in a given SonarQube instance
sonar.projectKey=com.organisation.project
# this is the name displayed in the SonarQube UI
sonar.projectName=ExampleProjectName
sonar.projectVersion=trunk
# Path is relative to the sonar-project.properties file. Replace "" by "/" on Windows.
sonar.sources=.
sonar.exclusions=**obj**,**Package**,**packages**,**globalize**,**node_modules**,**CMS**
