----------------------------------
Summary: Make Beam released artifacts reproducible
Key: BEAM-2727
URL: https://issues.apache.org/jira/browse/BEAM-2727
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
http://reproducible-builds.org/
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.
