>                 Key: BEAM-2727
>                 URL:
>             Project: Beam
>          Issue Type: Improvement
>          Components: build-system
>    Affects Versions: Not applicable
>            Reporter: Ismaël Mejía
>            Assignee: Ismaël Mejía
>            Priority: Minor
> There is a recent movement to create a verifiable path from source code to binary releases
in different open source projects. See
> For the case of Java binaries (classes and jars) if we want to have a reproducible build
we need to have a consistent build environment so we can reproduce those.
> For Beam we need to create an environment with a fixed version of the Java compiler,
maven and its plugins. This is addressed by BEAM-1534. But also by including the (JDK/Maven
versions) used to generate the jar artifacts in the information to validate at the vote. Additionally
we need to fix the Jar files because by default the maven-jar-plugin include the timestamp
of the build in the files which breaks the reproducibility of the process, fortunately there
is a Maven plugin that fixes this and that we can include in the release build.
