Maven Docker COPY只复制一个子目录，而不是整个构建上下文

我创建了一个虚拟项目，使用Java中的“Maven原型”。我想将整个构建上下文复制到Docker容器中

当我在当前目录中执行

ls-al

时，我得到以下结果：

drwxr-xr-x  12 my.user  staff    384 19 Aug 15:57 .
drwxr-xr-x  12 my.user  staff    384 19 Aug 15:39 ..
-rw-r--r--   1 my.user  staff     53 19 Aug 15:39 .dockerignore
-rw-r--r--   1 my.user  staff    295 19 Aug 15:39 .gitignore
drwxr-xr-x   7 my.user  staff    224 19 Aug 15:45 .idea
drwxr-xr-x   3 my.user  staff     96 19 Aug 15:39 .mvn
-rw-r--r--   1 my.user  staff     78 19 Aug 15:57 Dockerfile
-rwxrwxr-x   1 my.user  staff  10078 19 Aug 15:39 mvnw
-rw-rw-r--   1 my.user  staff   6609 19 Aug 15:39 mvnw.cmd
-rw-r--r--   1 my.user  staff   3691 19 Aug 15:39 pom.xml
drwxr-xr-x   4 my.user  staff    128 19 Aug 15:39 src
drwxr-xr-x  15 my.user  staff    480 19 Aug 15:40 target

这是我的

Dockerfile

：

FROM maven:3-jdk-11-slim
WORKDIR /home/mvn
COPY ./ .
RUN ls -al
RUN mvn verify

不幸的是，只有目标文件夹被复制。这是docker build的结果输出。：

这里可能有什么错误？

Quarkus Maven原型添加了一个

.dockrignore

文件。其中只有

target

文件夹未从Docker中排除。因此，只复制了

目标

文件夹。

您的

.dockrignore

中添加了一些内容。@atline谢谢，这就是解决方案！您是否愿意将您的解决方案@HaroldL.Brown发布给未来的用户，让他们了解需要什么来修复它？
