<p class="MsoNormal">Hi everybody,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am trying to understand how someone can independently verify the reproducibility of Java projects on Maven Central. Having explored the repositories on Maven Central, I could not find examples where the “buildinfo” file was present.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The archives of this mailing list pointed out examples such as
<a href="https://repo1.maven.org/maven2/com/typesafe/akka/akka-actor_2.13/2.6.4/akka-actor_2.13-2.6.4.buildinfo">
https://repo1.maven.org/maven2/com/typesafe/akka/akka-actor_2.13/2.6.4/akka-actor_2.13-2.6.4.buildinfo</a>, and yet my understanding is that this is not enough [but why?], hence reproducible-central was created to address some sort of gap.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So far, my mental model is that:<o:p></o:p></p>
<ul style="margin-top:0cm" type="disc">
<li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1">By including buildinfo in the artifacts on Maven Central, library authors empower users to check for themselves if the build is reproducible or not.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1 lfo1">Reproducible-central takes it a step further and attempts to do a build and then gives you a “yes/no” result.<o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thus, the former makes the problem solvable in principle, whereas the latter actually solves it. Is my understanding is correct?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Besides that, I have some additional questions:<o:p></o:p></p>
<p class="MsoNormal">1. Can you provide references to documentation that explains how to make sure buildinfo ends up on Maven Central?<o:p></o:p></p>
<p class="MsoNormal">2. Is there a tutorial that describes how to get featured on Reproducible Central?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I had a look at <a href="https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/doc/BUILDSPEC.md">
https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/doc/BUILDSPEC.md</a>, and my understanding is that this is not working for projects built on Windows, because it relies on rebuild.sh, which implies one has bash. The library I publish on
Maven Central is built on a Windows computer – does this mean that I won’t be able to list it in reproducible-builds?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Looking forward to your feedback,<o:p></o:p></p>
<p class="MsoNormal">Alex<o:p></o:p></p>
