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.

Hey @j2fxprgee,
We did not hear back from you in this thread. Is it safe to assume that the latest release has been resolved for you?
