可能的解决步骤 #

1. 确认父项目与依赖模块已构建
   当前项目依赖父工程openapi-generator-project及同项目下的openapi-generator模块，需确保父项目在本地目录结构中存在（对应<relativePath>../..</relativePath>），并已在父项目根目录执行mvn clean install，将相关模块安装到本地Maven仓库。

2. 强制更新快照依赖
   执行mvn clean install -U，-U参数会强制Maven更新快照版本依赖，避免本地缓存的旧快照导致解析失败。

3. 清理本地Maven仓库缓存
   删除本地Maven仓库中org/openapitools下的6.3.0-SNAPSHOT相关目录，再重新执行构建命令，解决缓存损坏或未更新的问题。

4. 验证目录结构与相对路径
   检查当前项目的目录层级是否符合父项目相对路径要求，示例正确结构：

   openapi-generator-project/
   └── [子目录]/
       └── openapi-generator-online/
           └── pom.xml
   

   若路径不符，修改<relativePath>为正确的父项目路径。

5. 检查Maven镜像配置
   确认settings.xml中的镜像仓库支持快照版本下载，部分公共镜像可能不允许获取快照依赖，可临时切换至Maven中央仓库或配置包含快照库的镜像。
