I'm still trying. If the following dependencies in pom.xml of shenyu-bootstrap are commented out during packaging, there will be no problem in running
```
<!-- apache shenyu data sync start use nacos-->
<dependency>
<groupId>org.apache.shenyu</groupId>
<artifactId>shenyu-spring-boot-starter-sync-data-nacos</artifactId>
<version>${project.version}</version>
</dependency>

I used the latest code to start locally and reported no repetition error. Please try to clean up the workspace thoroughly and repackage it.

It has been solved. It seems that it is really a version problem. 2.5.1-SNAPSHOT can be replaced by 2.5.1. Thank you very much for your answer
