NullPointerException with Sonar Gradle Plugin version 7.2.3.7755

SonarQube Server / Community Build Plugin Development
1

We use the lates version of Sonar Gradle Plugin (org.sonarqube:7.2.3.7755) with the following sonar configuration in gradle.build.

sonar {
    properties {
        property 'sonar.host.url', "${sonarHostURL}"
        property 'sonar.projectKey', "${sonarProjectKey}"
        property 'sonar.token', "${System.env.SONAR_AUTH_TOKEN}"
        property 'sonar.projectDescription' , 'Sample'
    }
}

If I start the “sonar” Gradle task I get the following Exception:

Caused by: java.lang.NullPointerException: Cannot invoke "Object.equals(Object)" because the return value of "java.util.Map.get(Object)" is null

If I use previous version of Gradle plugin (org.sonartype:7.2.2.6593) everything works fine.

If I remove the property “sonar.projectDescription” from the Gradle configuration the exception does not occur even with the lates version of the Gradle plugin.

Hint for workaround of fix for problem would be appreciated.

Hello @j2fxprgee,

Thank you for the feedback! This is a bug that was introduced in the latest version of the scanner. I have created a ticket for us to fix it.
