- 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).

Add missing source bundles for
- org.eclipse.jgit.ant
- org.eclipse.jgit.archive
- org.eclipse.jgit.http.apache
- org.eclipse.jgit.http.server
- org.eclipse.jgit.junit
- org.eclipse.jgit.junit.http
- org.eclipse.jgit.junit.ssh
- org.eclipse.jgit.lfs
- org.eclipse.jgit.lfs.server
- org.eclipse.jgit.ui
Combine all source bundles into a single source feature
org.eclipse.jgit.source and delete the other source features.
Ensure all bundles are added to the jgit p2 repository.

Create the bundle and move the SshTestGitServer there. Verified that
the Eclipse build still works and ran JSchSshTest and ApacheSshTest as
junit tests inside Eclipse.
Update maven build and features to account for that. Verified by
running full maven build including packaging.
Update bazel build files to account for that. Verified by a
clean-slate bazel build :all, followed by running the JSchSshTest
and the ApacheSshTest via bazel.

Add a simple ssh git server based on Apache MINA sshd, and use it
in new tests that verify ssh operations and in particular a number
of bugs that had cropped up over time in JSch.
The git server supports fetching only, and sftp access.
The tests are all in an abstract base class; the concrete JschSshTest
class only provides ssh-specific test setup. So the same tests could
be run easily also with some other ssh client.
