Could you please provide a small but detailed demo to reproduce this bug including testing environment, steps to take? Would be nice for use to investigate further into this problem.
Intuitively, this looks like a jar dependency conflicts to me, maybe we can start from here 😄

@heshengjun811 I think you can try add this to your logback.xml
```
<appender name="mqAsyncAppender1" class="ch.qos.logback.classic.AsyncAppender">
<queueSize>1024</queueSize>
<discardingThreshold>80</discardingThreshold>
<maxFlushTime>2000</maxFlushTime>
<neverBlock>true</neverBlock>
<appender-ref ref="mqAppender1"/>
</appender>
``` according to [logback example](https://rocketmq.apache.org/docs/logappender-example/)
The whole logback.xml looks like
```
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="mqAppender1" class="org.apache.rocketmq.logappender.logback.RocketmqLogbackAppender">
<tag>TagA</tag>
<topic>01_test</topic>
<producerGroup>group1</producerGroup>
<nameServerAddress>127.0.0.1:9876</nameServerAddress>
<layout>
<pattern>%date %p %t - %m%n</pattern>
</layout>
</appender>
<appender name="mqAsyncAppender1" class="ch.qos.logback.classic.AsyncAppender">
<queueSize>1024</queueSize>
<discardingThreshold>80</discardingThreshold>
<maxFlushTime>2000</maxFlushTime>
<neverBlock>true</neverBlock>
<appender-ref ref="mqAppender1"/>
</appender>
<root>
<level value="debug"/>
<appender-ref ref="mqAppender1"/>
</root>
<logger name="testLogger" level="debug" additivity="true">
<appender-ref ref="mqAppender1"/>
</logger>
</configuration>
```
Once I added this, it will work properly.

```
Once I added this, it will work properly. The reason for NoClassDefFoundError was because we missed some configuration entries, the static initialization process of some class (I don't know which exact class it is) failed, and throws NoClassDefFoundError.
