Docker for Windows exits with code 127 when building image

When I try to build this Docker-Image, I get the following error:

Log

FROM java:8

WORKDIR /app

ADD . /app

EXPOSE 8080

RUN ./gradlew build

CMD ./gradlew bootRun

When I just build the app with "gradlew build" it runs and when I try to run this Docker Image with a Mac, it works too, just not for windows

EDIT:

RUN ls Image

Worked for me, adding in the dockerfile, before RUN ./gradlew lib:build:

RUN apt-get update && \
    apt-get install dos2unix && \
    apt-get clean
RUN dos2unix gradlew
RUN chmod +x gradlew
RUN ./gradlew lib:build

This is not a great answer, but what I found is that when Windows mounts files into Docker from Windows, it leaves Windows-like line endings on the mounted files. A janky way to solve it in your Dockerfile would be to install dos2unix in the container and add a

RUN dos2unix gradlew

prior to executing your build process. Unfortunately, this is a TERRIBLE solution. Hopefully Docker for Windows on WSL2 that is supposed to release soon will solve this better but for now you are stuck with this janky solution.

gradlew must be marked as executable.

chmod +x gradlew

Mac and Linux share permissions scheme but Windows needs to use a virtual FS so it copies files with default permissions - 644 and you need 755.
