无法执行目标org.sonarsource.scanner.maven：sonar-maven-plugin：null：MojoExecutionException：NullPointerException

问题描述

*当我运行mvn sonar：sonar时，出现此错误。我尝试了许多方法来解决它，并且在pom.xml文件中做了很多更改，但是找不到正确的解决方案。 我使用了7.6版本的Sonar Qube java8。

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）：目标：NullPointerException-> [帮助1]

找不到解决方案，任何人都可以提供解决方案 这个错误？

这是我项目的pom.xml文件。
