我正在尝试在Dockerfile的构建器阶段构建项目。 在下一阶段，我想将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
