Subject [jira] [Commented] (MNG-6276) Support reproducible builds
Date Mon, 28 Aug 2017 10:41:00 GMT

    [ https://issues.apache.org/jira/browse/MNG-6276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16143619#comment-16143619

Robert Scholte commented on MNG-6276:
-------------------------------------

I'm not convinced  that "reproducabile builds" is the most widely used term, especially if
https://reproducible-builds.org/ is used for that information. IMHO the term is not complete
enough. {{Idempotent}} is used within the http world and describes how GET, POST, PUT etc
should behave.
I like the word {{deterministic}}, which is indeed more common word and better reflects its
purpose.

The annotation is a way for the developer to say: this plugin supports X. Without it, it could
still support it, but there's no way to verify it. If you want to ensure a deterministic build,
all your plugins should support it. For instance: in case of maven-resource-plugin, you MUST
specify an EOL-String to ensure that line-endings of text-files don't depend on the OS.

>                 URL: https://issues.apache.org/jira/browse/MNG-6276
>             Project: Maven
>          Issue Type: New Feature
>          Components: core, General
>            Reporter: Paolo Sacconier

> A venerable build system like maven should support full build reproduibilty (i.e. producing
bit a bit identical binaries from the same source).
> As initiatives like https://reproducible-builds.org gain traction and the news of the
recent Debian policy change to mandate this build behavior (see https://reproducible.alioth.debian.org/blog/posts/121/),
this seems a feature that needs to be considered for inclusion into maven core.
> There is an indipendent ongoing effort to support this feature and the author stated
that he has found interest from maven project to integrate his work: https://github.com/Zlika/reproducible-build-maven-plugin/issues/6#issuecomment-325005883
> I hope this issue helps kickstart the effort.
