docker repository和tag出现<none>

Question

我正试图从github构建docker镜像。我正在运行以下命令来构建映像。

docker build -t test1:latest https://github.com/syndy1989/Accessibility.git

我收到以下错误：

PS C:\Users\Administrator> docker build -t test1:latest https://github.com/syndy1989/Accessibility.git

当我在Docker容器内部检查时，sample.java被复制到文件夹C：/ axe_accessibility中。我能够在容器内编译，但在构建图像时它不能正常工作。对此有任何建议会有所帮助。提前谢谢。
