Could not initialize Logback Nacos logging from classpath:nacos-logback14.xml #7

问题描述

Nacos Client 升级至 2.4.0 以后，已有工程运行出错。

个人的环境是：Spring Boot 3.3.1、Spring Cloud 2023.0.3、Spring Cloud Alibaba 2023.0.1.2。

在这个环境下使用 Nacos Client 2.3.3 + Nacos Server 2.3.2 运行正常，全部切换至 2.4.0 出错。

手动将 Nacos Client 依赖的 logback-adapter 排除才能运行。

错误信息如下：

重现代码

重现，见 https://github.com/herodotus-ecosystem/nacos-reproduce

目测，是 Bootstrap 模式会加载日志两次。logback-adapter 包除了日志配置文件 nacos-logback14.xml 外，还有代码会动态往 logback 中加内容，所以启动报错。
