`RUN ./gradlew build -x test` command error

Question

I have been trying to install conductor using docker but I have been constantly getting errors. I tried using [https://github.com/Netflix/conductor/tree/main/docker][1] commands as given in this. But the first command didnt work(gradlew build) I instead used gradlew init. When running the second command (docker build -t conductor:server ./server)

I am using windows I tried changing RUN ./gradlew build -x test to .\gradlew,gradlew,gradle,..\gradlew,../gradlew but nothing has worked.

Thank you

Answer 1

Let me disclose steps I've executed, which is explained on, https://github.com/Netflix/conductor/issues/1814.

1. Delete your current conductor folder
2. Run git config --global core.autocrlf false; or simply make sure it is already set if you ran in the past
3. Clone conductor repo again
4. Check if end of lines shows as CRLF via NotePad++ by opening a DockerFile, e.g. => conductor/docker/server/DockerFile
5. Run docker-compose up on conductor/docker

This worked for me!

Answer 2

The root cause is that the file gradlew is DOS format on windows. You need to transfer the file format to unix format in advance before compose or build, so you need add :

RUN apt-get update && apt-get install -y dos2unix && dos2unix gradlew
RUN find ./ -name "*.java" | xargs dos2unix

before

RUN ./gradlew build -x test

in the DockerFile which under server fold.
