我遇到了“拒绝访问”的问题。连接到Sonar数据库时出错。跟踪下方：

在Jenkins配置中，正确设置了数据库URL，数据库登录和数据库密码。使用此URL和凭据，可以通过mysql命令行客户端登录，我们可以查看声纳数据库表。 我们还检查了数据库用户的权限，并正确设置了这些权限。 我们检查了sonar.properties文件，所有内容都被注释掉了。
如果我们将sonar.jdbc.username和sonar.jdbc.password添加到项目属性，则与数据库的连接是成功的。但密码是纯文本，这是不可取的。
有谁知道为什么不使用系统配置的凭据？什么是解决方案？这是SonarQube中的错误吗？
