Java Docker多级复制：没有这样的文件或目录

我试图在Dockerfile的builder阶段构建项目。 在下一个阶段，我想把lib_ivy复制到该阶段的WORKDIR

FROM pranaysankpal/ant:v0.1 as builder
ARG APP_DIR=/var/builder
COPY build-only $APP_DIR/build-only
COPY lib $APP_DIR/lib
COPY ivy.xml $APP_DIR
COPY ivysettings-local.xml $APP_DIR
COPY build.xml $APP_DIR
WORKDIR $APP_DIR
RUN ant clean resolve
RUN pwd
RUN ls -la

FROM pranaysankpal/ant:v0.1 as compiler
ARG APP_DIR=/var/www/we-api
WORKDIR $APP_DIR
COPY —-from=builder /var/builder/lib_ivy .
CMD tail -f /dev/null

ls和pwd步骤的输出为：

Step 10/16 : RUN pwd
 ---> Running in 26cab920f381
/var/builder

Step 11/16 : RUN ls -la

复制步骤的输出为：

STEP 15/16: COPY —-from=builder /var/builder/lib_ivy .
COPY failed: stat /var/lib/docker/tmp/docker-builder118710200/—-from=builder: no such file or directory

你在玩什么版本的Docker？（我认为CentOS/RHEL 7附带的版本太旧，无法支持

COPY-from

）我发现，这是一个字符编码问题<代码>复制--从，问题在于--非常好！谢谢你的帮助！你在玩什么版本的Docker？（我认为CentOS/RHEL 7附带的版本太旧，无法支持
