未能执行目标 org.sonarsource.scanner.maven:sonar-maven-plugin: null: MojoExecutionException: NullPointerException

Question

* 当我运行 mvn sonar:sonar 时，我得到了这个错误。我尝试了很多方法来解决它，并对 pom.xml 文件进行了很多更改，但无法找到正确的解决方案。 我用的是java8，Sonar Qube 7.6版本。

如何在 SonarQube 上集成 maven 项目或如何在 pom.xml 文件中生成 maven 项目的报告？

[错误] 无法在项目 BankAccount 上执行目标 org.sonarsource.scanner.maven:sonar-maven-plugin:3.7.0.1746:sonar (default-cli): null: MojoExecutionException: NullPointerException -> [帮助1]

找不到解决办法，谁能给个解决办法 这个错误？

这是我项目的 pom.xml 文件。
