Question

我已经从他们的GitHub镜像存储库中检出了openmeetings的最新代码。在运行openmeeting-web时，我遇到了异常。

我理解异常是由于多个slf4j罐子而来。但我没有得到解决此错误的确切解决方案。请帮忙。

如果您从源代码构建，则最需要unpacked构建，如下所述： http://openmeetings.apache.org/BuildInstructions.html#Tips_and_Gotchas

然后执行

cd openmeetings-server/target/server ./red5-debug.sh

运行openmeeting-web时发生异常
