Error while executing gradle command in docker file

FROM gradle:4.2.1-jdk8-alpine
WORKDIR /app
ADD --chown=gradle:gradle /app/producer /app
RUN ./gradlew build --stacktrace

Project Structure is as follows . It is a muti module project:

 <code>
        --springbootdocker (Root folder of project) <br>
          --producer (Sub module Producer) <br> 
            -- Dockerfile (for Producer)<br>
          --consumer (Sub module Consumer) <br>
            -- Dockerfile (for Consumer)<br
    </code>

This is the docker file.
While doing docker build: getting this error

failed to build: ADD failed: stat /var/lib/docker/tmp/docker-builder561553413/app/producer: no such file or directory

This is the dockerfile which is currently working without any error.

FROM gradle:4.10.0-jdk8-alpine AS build
COPY --chown=gradle:gradle . /home/gradle/src/producer
WORKDIR /home/gradle/src/producer
RUN gradle bootJar --no-daemon --stacktrace
FROM openjdk:8-jdk-alpine
ARG JAR_FILE=build/libs/*.jar
COPY --from=build /home/gradle/src/producer/build/libs/*.jar producer.jar
ENTRYPOINT ["java","-jar","/producer.jar"]

Here you have to fix a couple of things in your Dockerfile.

  1. ADD command ADD command requires two parameters <src> and <dest>. So, you should provide producer path from the host as src container path as dest. But in such cases recommended to use COPY command.

    COPY --chown=gradle:gradle producer /app/producer

  2. RUN ./gradlew It should be just gradle and it's WORKDIR should be /app/producer. If not it'll fail and you'll get,

    Failed to create parent directory '/app/.gradle' when creating directory '/app/.gradle/4.2.1/fileHashes' error when running gradle command. Because the WORKDIR /app owns by user root.

  3. Recommend to divide RUN gradle build --stacktrace as ENTRYPOINT and CMD.

    Complete Dockerfile

FROM gradle:4.2.1-jdk8-alpine
WORKDIR /app
COPY --chown=gradle:gradle producer /app/producer
WORKDIR /app/producer
ENTRYPOINT ["gradle"]
CMD ["build", "--stacktrace"]

The partial output of docker build

Starting a Gradle Daemon (subsequent builds will be faster)

ADDed files need to be under the directory where the docker build is being run from, so depending on your structure you probably want something like:

ADD myProject /app

Assuming you have a structure like:

Dockerfile
myProject/
