- configure Maven to run build reproducibly [1]
- use UTC timestamp of checked out commit as build timestamp
- add git-describe, git-commit-id, git-commit-id, git-tags,
git-remote-origin-url to MANIFEST.MF files
- configure cyclonedx-maven-plugin to also use UTC timestamp of
checked out commit
- for packaging build use tycho-buildtimestamp-jgit [2] to ensure
version uses the timestamp of the last commit
- SBOMs are not reproducible by design [3] they should have a build
timestamp matching the time when the build was executed and a serial
number which is a unique UUID per build run. Hence exclude them from
comparison [4].
- Use gmavenplus-plugin to format build timestamps. Maven expects
build timestamp in ISO-8601 format, to replace the qualifier in
versions the timestamp format must be compatible with rules for OSGi
version numbers. Didn't find a way to read the properties set by the
git-commit-id-maven-plugin from another plugin. Hence use JGit in a
groovy script to get the commit time of the current HEAD and provide
it in these two formats.
TODO: packaging build (features and p2 repository) is not yet binary
reproducible since that's not yet supported by Tycho [5], artefacts have
reproducible version numbers but file lastModified timestamps are not
yet reproducible.
Test plan for Maven build:
- build using
mvn clean install"
- verify second build is reproducible:
mvn -T1 clean verify artifact:compare
verification seems not to be thread-safe, hence run it with a single
thread using option -T1
For packaging build (still fails due to non-reproducible file
timestamps):
- build using
mvn -f org.eclipse.jgit.packaging/pom.xml clean install
- verify second build is reproducible:
mvn -T1 -f org.eclipse.jgit.packaging/pom.xml clean verify artifact:compare

Purpose of the next branch is preparation of breaking changes before
we know when we will release it. Bump the version to the next major
release 6.0.0-SNAPSHOT in order to prevent build results compete with
build results from the version currently used on the master branch
(5.7.0-SNAPSHOT).
