Docker镜像构建成功但上传失败，需修复警告并上传至Amazon ECR

问题根源 #

你遇到的StageNameCasing警告并非来自Jenkins Pipeline的stage定义，而是来自构建镜像时使用的多阶段Dockerfile。报错提示的BUILD_IMAGE是Dockerfile中定义的构建阶段名称，ECR要求阶段名使用小写格式。

解决方案 #

找到Jenkins Pipeline中指定的Dockerfile路径./Docker-files/app/multistage/Dockerfile，将其中大写的阶段名BUILD_IMAGE改为小写（比如build_image），同时同步修改所有引用该阶段的代码。

修改示例 #

原Dockerfile中的阶段定义：

FROM maven:3.8.6-openjdk-17 AS BUILD_IMAGE
# 构建步骤...

修改后：

FROM maven:3.8.6-openjdk-17 AS build_image
# 构建步骤...

如果Dockerfile中后续有引用该阶段的代码，也要同步改为小写：

COPY --from=build_image /path/to/artifact /target/path

验证步骤 #

1. 保存修改后的Dockerfile
2. 重新运行Jenkins Pipeline，触发镜像构建与上传
3. 检查是否仍有StageNameCasing警告，确认镜像成功上传至ECR

你的Jenkins Pipeline代码参考 #
