Hi, At Log4j we have solved all the reproducibility problems mentioned on the wiki page[1] and we are approaching the problem of reproducibility between different OSes.
My goal is for the following procedure to work regardless of the operating system of the user: 1. a user checks out a tagged release from the Git repository, 2. the user runs the Maven Wrapper: 'mvn package' 3. the user checks the SHA256 of the resulting JAR file with the one from Maven Central. The only problem I have encountered so far is the difference between line endings on Windows and UNIX systems. The line endings of static resources can be easily fixed using a `.gitattributes` file, but the line endings of resources generated by plugins may vary. Many plugins respect `System.lineSeparator()`, but setting the `line.separator` Java system property on the command line is no trivial task and it can not certainly be done in `.mvn/jvm.config`. What do you think about introducing a POM-like system property (e.g. `project.build.lineSeparator`) that would allow setting `line.separator` using a simple `-Dproject.build.lineSeparator=LF` or `-Dproject.build.lineSeparator=CRLF`? Ideally this could be a real POM property, but I am afraid that by the time the POM is resolved, `System.lineSeparator()` is already initialized.
