docker build fails during ./mvnw clean package

[apeiris]

I have installed maven :
C:\Users\mapei\eclipse-workspace\OpenAs2App>mvnw --version
Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T07:57:37-04:00)

OS name: "windows 11", version: "10.0", arch: "amd64", family: "dos"

when the docker build -t openas2:latest .
it fails with
=> [builder 5/11] RUN rm -f Remote/dist/* 0.8s
=> [builder 6/11] RUN rm -f Bundle/dist/* 1.0s
=> ERROR [builder 7/11] RUN ./mvnw clean package

Try running the command on its own to get a better idea of what is failing:
./mvnw clean package

Hi, Make sure you have allocated enough resources for your Docker containers. Java typically is very memory hungry when it comes to compiling and building. Regards, J

fork @ https://github.com/anbansal/OpenAs2App has the solution implemented with sed command. It is because of line-ending character mismatch when bundling the docker image

changes as below can solve the issue (works in Windows 11)

RUN rm -f Bundle/dist/*

RUN sed -i 's/\r$//' mvnw

RUN ./mvnw clean package
RUN mkdir ./Runtime && unzip Server/dist/OpenAS2Server-*.zip -d Runtime
RUN ./mvnw clean

Not sure if you are using the OpenAS2 official package or a fork but hethis command:
sed -i 's/\r$//' mvnw
... has no effect because the file ( mvnw in the root of the OpenAS2 repository) does not contain \r characters in the official OpenAS2 deployment and never has had.

Just a mention why this is necessary on Windows: The default of Git for Windows is to set line endings of text files to "CR LF" on pull. Pushing the files will replace the line ending back to "LF", see https://docs.github.com/de/get-started/getting-started-with-git/configuring-git-to-handle-line-endings.

This is always an issue with Docker images if the files are just copied into the image as the line ending is "CR LF" then.

There are typically two ways to handle this:

• Set the line endings to LF in the repo via .gitattributes ("* text=auto eol=lf" in the first line)
• Replace "CR LF" to "LF" as shown with sed above during build
