Sonarqube Webapp没有启动
我在Windows下使用PostgreSQL9.5安装SN5.5。 不幸的是，我遇到了错误“Webapp没有启动”。
以下是完整的堆栈跟踪。 我想我得到了错误，首先在“异常发送上下文初始化事件到类org.sonar.server.platform.PlatformServletContextListener的监听器实例”

<-- Wrapper Stopped
org.sonar.api.utils.MessageException: Current version is too old. Please upgrade to Long Term Support version firstly.
这个日志意味着你要升级到最新版本。 你应该先升级到最接近的LTS版本（可能是4.5.X），然后你就可以升级到5.5。
有关升级策略的更多信息，请参见http://docs.sonarqube.org/display/SONAR/Upgrading。
你可以尝试在wrapper.conf文件中添加下面的属性。 它为我做了诡计。
