我们已将 sonarqube 从 7.4 升级到 7.9.1，我们需要将 sonar-crowd 插件从 2.1.1 升级到 2.1.3。
升级后，声纳应用程序在没有 Crowd 配置的情况下按预期启动。但是在与人群一起启动时，它在启动时失败了。
这是声纳属性上的人群配置
#-------------------
# Sonar Crowd Plugin
#-------------------
# To first try to authenticate against the external sytem.
# If the external system is not reachable or if the user is not defined in the external system, the authentication will be performed through the SonarQube internal system.
sonar.security.realm=Crowd
# URL of the Crowd server.
crowd.url=https://mycompany:8443/crowd/
# Crowd application name.
# Default is 'sonar'.
crowd.application=sonar
# Crowd application password.
crowd.password=password
# Crowd group sync
crowd.groups.sync=true
# Don't use crowd for sonar account
sonar.security.localUsers=admin,sonar
# Don't save passwords incase Crowd is down
sonar.security.savePassword=false
# Don't create users, they must come from Crowd
sonar.authenticator.createUsers=false
sonar-crowd 2.1.3 是否有任何依赖插件？这是最新 sonarqube 版本（7.9.1）的网络日志错误
