Enable Maven reproducible builds - 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 [1] https://maven.apache.org/guides/mini/guide-reproducible-builds.html [2] https://wiki.eclipse.org/Tycho/Reproducible_Version_Qualifiers [3] https://github.com/CycloneDX/cyclonedx-maven-plugin/issues/84 [4] https://maven.apache.org/plugins/maven-artifact-plugin/compare-mojo.html [5] https://github.com/eclipse-tycho/tycho/issues/233 Change-Id: I0202f55a1b6ae0edd922cfef638beb39d2ce9417
