How to solve the error, while running "docker build" on macOS terminal

trying to build Docker on my Mac. On Windows I did the same thing and it worked perfectly. But on Mac, I am getting this issue. I have tried "docker build --add-host=docker:10.180.0.1 . " to fix this but I am not quite sure why this thing is happening. since I am new in docker, maybe on Mac it needs some other setting than Windows. I also tried to run from root user, but failed.

gobinda@macos project-dev % docker-compose up --build

ERROR: Service 'app-server' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder412226086/known_hosts: no such file or directory

my Dockerfile: 

### Should only be used with mvn dockerfile:build
### Simple docker build . will produce errors

FROM nandi/repo:java8-mvn3.6.3
WORKDIR /app

VOLUME /tmp

# Build all the dependencies in preparation to go offline.
# This is a separate step so the dependencies will be cached unless
# the pom.xml file has changed.
COPY pom.xml .

RUN mvn dependency:go-offline -B

# Copy the project source
COPY src src

# Package the application
COPY additional/ /root/.repo/
RUN mvn package -DskipTests
RUN mkdir /root/fsys
COPY known_hosts /root/.ssh/known_hosts

##### Stage 2: A minimal docker image with command to run the app
#FROM openjdk:8-jre-alpine
#
#ARG DEPENDENCY=/target/dependency
#
## Copy project dependencies from the build stage
#COPY --from=build ${DEPENDENCY}/ /app/
##COPY --from=build ${DEPENDENCY}/META-INF /app/META-INF
##COPY --from=build ${DEPENDENCY}/BOOT-INF/classes /app

ENTRYPOINT ["java","-jar", "target/repo-1.0-SNAPSHOT.jar"]

what could be the possible solution for this? thanks in advance :)

Check if this file exists known_hosts in your codebase, maybe this file is ignored by .gitignore or .dockerignore your docker build is not working because it can't copy this file also check the permission of this file on mac.
