RUN mv - Directory not found at Dockerfile

I'm doing a Dockerfile to construct a Gradle program at Cloud, I'm having an issue at the command RUN mv build/libs/ComponentName-?.?.?.jar build/libs/app.jar that says that the directory build/libs/app.jar doesn't exist.

I already looking in internet trying to find solutions and all said that is basically a Syntax problem but not really what I need, I'm new in all of this of Docker so I'm not sure what to do.

This is the dockerfile block:

FROM maven:3.8.5-openjdk-17 as builder
RUN mkdir /app
WORKDIR /app
ARG ARTIFACTORY_USER
ARG ARTIFACTORY_PASSWORD
COPY . /app
RUN ./gradlew build
RUN mv build/libs/Component-Name-?.?.?.jar build/libs/app.jar
RUN ls -l build/libs

FROM registry.access.redhat.com/ubi9/openjdk-17-runtime:latest
USER 0
RUN mkdir /app
RUN chown -R 185:0 /app
RUN microdnf update -y

USER 185
WORKDIR /app
ARG APP_NAME=Component-Name-k8s
COPY --from=builder /app/build/libs/app.jar /app

# Start service
EXPOSE 8093
ENTRYPOINT java -jar app.jar

And this is the error that I'm recieving:

ERROR: process "/bin/sh -c mv build/libs/Component-Name-?.?.?.jar build/libs/app.jar" did not complete successfully: exit code: 1

Solution

  • You probably have multiple files that match build/libs/Component-Name-?.?.?.jar.

    In that case, you give 3 or more arguments to mv.

    If you give 3 or more arguments to mv, the last argument has to be an existing diretory into which all other arguments are moved.

    To make it work with wildcards, make sure to only match one file, for example by deleting build/libs/Component-Name-?.?.?.jar before running the build, or similar.
