 The ability to execute the SonarQube analysis via a regular Gradle task makes it available anywhere Gradle is available (developer build, CI server, etc.), without the need to manually download, setup, and maintain a SonarQube Runner installation. The Gradle build already has much of the information needed for SonarQube to successfully analyze a project. By preconfiguring the analysis based on that information, the need for manual configuration is reduced significantly. 
 
 ## Prerequisites
-* Gradle versions 2.14+
+* Gradle versions 3+
 * At least the minimal version of Java supported by your SonarQube server is in use 
 
 Bytecode created by javac compilation is required for Java analysis, including Android projects.

 ## Task dependencies
-All tasks that produce output that should be included in the SonarQube analysis need to be executed before the `sonarqube` task runs. Typically, these are compile tasks, test tasks, and code coverage tasks. To meet these needs, the plugins adds a task dependency from `sonarqube` on `test` if the Java plugin is applied. Further task dependencies can be added as needed. For example:

+
+Starting with v3.0 of the SonarScanner for Gradle, task dependencies are no longer added automatically. Instead, the SonarScanner plugin enforces the correct order of tasks with `mustRunAfter`. You need to be either manually run the tasks that produce output before `sonarqube`, or you can add a dependency to the build script:

 ```
 // build.gradle
 project.tasks["sonarqube"].dependsOn "anotherTask"
