执行部署命令后不停的重复打包上传

因为包大小超过了 50M，部署时选择使用 NAS

第一次部署，命令行显示是成功的（调用函数报错说找不到 /code/boostrap，但这应该是别的问题了）

后面执行 fun build，再 fun deploy -y，就出现了重复打包上传的问题：

Fun has automatically uploaded your code dependency to NAS, then fun will use 'fun deploy todomato-user-service/user-function' to redeploy.

这是一个 Spring Boot 项目，先前使用 fun deploy -y 转换成函数计算
template.yml：

```yml

boostrap:

```sh
#!/usr/bin/env bash
export PORT=9000
export CLASSPATH="$CLASSPATH:./target/user-service-1.0.jar"
java -Dserver.port=$PORT org.springframework.boot.loader.PropertiesLauncher
```

Start with template.yml, especially CodeUri, NasConfig, and the generated user-function, then reproduce the sequence with fun build followed by fun deploy -y. Trace the packaging and NAS upload flow shown in the deployment output and compare it with the bootstrap entry point. Done means one deployment packages and uploads the code once instead of repeatedly.
