Michael Osipov commented on MSHARED-837:
----------------------------------------
As for the style: The ISO definition provides two styles basic and extended.
Basic can drop {{-}} and {{::}} delimiters while extended retains them. All
components date, time, offset but be either basic or extended format. You are
not allowed to mix them. Just using {{X}} with the extended style would allow
{{2019-10-11T10:56:00+02}} (valid), {{2019-10-11T10:56:00+0200}} (invalid) and
{{2019-10-11T10:56:00+02}} (valid). In basic format this would be
{{20191011T105600+02}} (valid), {{20191011T105600+0200}} (valid) and
{{20191011T105600+02:00}} (invalid).
This is due to the lenient and telescoping nature of SDF. See also
[here|https://stackoverflow.com/q/13088140/696632]. So you can only use the
extended format with this implementation and stick to {{XXX}} and all is fine.
I don't think that just changing code and updating test would have really
helped because I wanted you just to understand what I object here since you
didn't understand how telescoping in SDF works. Principal understanding is more
important that pure code. I will change my branch accordingly with the tests.

> Reporter: Herve Boutemy
> Assignee: Herve Boutemy

> Fix For: maven-archiver-3.4.1

>
> creating an archive in a Reproducible Builds way requires to configure
> archiver with an output timestamp: see
> https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=74682318
> The timestamp value can't be natively injected as Date with Plexus, because
> Plexus Date injection uses local timezone, then is not reproducible: see
> https://codehaus-plexus.github.io/plexus-containers/plexus-container-default/xref/org/codehaus/plexus/component/configurator/converters/basic/DateConverter.html
> Then we need top inject ${project.build.outputTimestamp} as a String and
> provide an API to parse this String to a Date, before calling
> plexus-archiver's configureReproducible
