Review Comment:
> 1. We need `project.build.outputTimestamp` in the `pom.xml` as it's
used by maven plugins to ensure the build is reproducible.
Yes. I think so too.
> 2. `project.build.outputTimestamp` value has to be fixed (not changing
at each build). The value doesn't matter if it's always the same. That's the
purpose of the setting the value (it's what I did in all other Apache projects
where I'm working on).
Yes. I think so too.
> 3. We can't use `1970-01-01` else maven-assembly-plugin complains,
that's why I used the first allowed value in the range which is
`1980-01-01T00:00:02Z`. So I used the same in the `test-helper.rb` to be in
sync.
Yes and no. We don't need to use special timestamps such as `1970-...` and
`1980-...` in `pom.xml`. `test-helper.rb` normalizes all timestamps such as
`2023-12-13T00:00:00Z` in `pom.xml`. So we don't need to synchronize timestamps
in `pom.xml` and `test-helper.rb`. So we can use `2023-12-13T00:00:00Z` in
`pom.xml` like you did.
