If you are having trouble adding a SonarQube server authentication token to Jenkins, follow these steps to troubleshoot and resolve the issue:
1. Verify SonarQube server URL and credentials: Ensure that you have the correct SonarQube server URL and credentials (username and password) for the authentication token. Double-check for any typos or errors in the information.
2. Generate a new authentication token: If you have already used the current authentication token or it has expired, generate a new one from the SonarQube server. To do this, log in to the SonarQube server, navigate to "Administration" > "Security" > "General Settings," and click the "Generate" button next to the "Authentication token" field. Copy the new token.
3. Update Jenkins with the new authentication token: In the Jenkins "Manage Jenkins" section, click on "Configure System." Scroll down to the "SonarQube Servers" section and select the SonarQube server you want to configure. Enter the updated SonarQube server URL, username, and the new authentication token in the respective fields. Save the changes.
4. Verify Jenkins plugin version: Ensure that you are using the latest version of the SonarQube Scanner plugin for Jenkins. Outdated plugins might not be compatible with the latest SonarQube server version. To update the plugin, go to "Manage Jenkins" > "Manage Plugins," find the SonarQube Scanner plugin, and click "Update."
5. Check Jenkins job configuration: Verify that your Jenkins job is configured to use the SonarQube server you just updated. In the job configuration, under the "Build" section, ensure that the "Analyze source code with SonarQube" checkbox is selected and the correct SonarQube server is selected from the dropdown menu.
6. Test the connection: Run a test Jenkins job to see if the connection to the SonarQube server is successful. If the job fails, check the console output for any error messages related to the SonarQube server or authentication token.
If you continue to face issues, consult the Jenkins and SonarQube documentation, or reach out to their support communities for further assistance.
