Dear List, I'm currently trying to make Processing <https://processing.org> build reproducibly (so building it twice yields the exact same output file). Currently this involves, as far as I can tell, unzipping every JAR file, touching the files with a constant modification time, and re-zipping it. (Even if you were to touch the .class files in advance, there's MANIFEST.MF, which is created by Ant and which you have to unzip to access.)
Unless there's some efficient way of doing this that I've missed, could you advise me on how I'd go about writing a patch for Ant that makes reproducible JARs easier? I'd been thinking of adding a "modificationtime" attribute to the jar and zip tasks, and giving that time to all the files, but I'd be grateful if you could give me a rough idea of how Ant works and which files I'd need to be looking at and editing. Thanks, George Bateman. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@ant.apache.org For additional commands, e-mail: dev-h...@ant.apache.org
