- 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

Packfiles having an equivalent .keep file are associated with in-flight
pushes that haven't been completed, with potentially a set of git
objects not yet referenced by a ref.
If the Git client is not up-to-date, it may result in pushing a
packfile, generating a <packfile>.keep on the server, which
may also contain existing commits due to the lack of Git protocol
negotiation in the git-receive-pack.
The Git protocol negotiation is the phase where the client and the
server exchange the list of refs they have for trying to find a common
base and minimise the amount of objects to be transferred.
The repack phase in GC was previously skipping all objects that were
contained in all packfiles having a <packfile>.keep file associated
(aka "locked packfiles"), which did not take into consideration the
fact that excluding the existing commits would have resulted in the
generation of an invalid bitmap file.
The code for excluding the objects in the locked packfiles was written
well before the bitmap was introduced, hence could not consider a use
case that did not exist at that time.
However, when the bitmap was introduced, the exclusion of locked
packfiles was not changed, hence creating a potential problem.
The issue went unnoticed for many years because the bitmap generation
was disabled when JGit noticed any locked packfiles; however, the
bitmaps are enabled again since Id722e68d9f , and the the issue is now
visible and is impacting the GC repack phase.
Introduce the '--pack-kept-objects' option in GC for including the
objects contained in the locked packfiles during the repack phase,
which is not an issue because of the following:
- If there are any existing commits duplicated in the packfiles
they will be just considered once anyway because the repack doesn't
generate duplicates in the output packfile.
- If there are any new commits that do not have any ref pointing to
them, they will be automatically excluded from the output repacked
packfile.
The same identical solution is adopted in the C implementation of git
in repack.c.
Because the locked packfile is not pruned, any new commits not pointed
by any refs will remain in the repository and there will not be any
accidental pruning or object loss as it is today before this change.
As a side-effect of this change, it is now potentially possible to still
have duplicate BLOBs after GC when the keep packfile contained existing
objects. However, it is way better to keep the duplication until the
next GC phase rather than omitting existing objects from repacking and,
therefore generating an invalid bitmap and incorrect packfile.

OSGi can have its plugin localization at an arbitrary place; there is
no need to have it in a top-level plugin.properties file. In non-OSGi
environments having the files at the root level may mean that these
files clash with each other, or, as in the referenced bug, with some
third-party plug-in's plugin.properties, which may not even have
anything to do with localization.
Move our OSGi localization to a subfolder OSGI-INF/l10n. For OSGi
environments, that's just as good, and for non-OSGi environments it
avoid clashes with other root level items on the classpath or in a fat
JAR.
For fragments, use neither plugin.properties (which would clash with the
host plug-in's plugin.properties) nor fragment.properties (which might
clash with other fragments for the same fragment host bundle). Instead
use names "relative" to the host bundle.

This fixes all the javadoc warnings, stops ignoring doclint 'missing'
category and fails the build on javadoc warnings for public and
protected classes and class members.
Since javadoc doesn't allow access specifiers when specifying doclint
configuration we cannot set `-Xdoclint:all,-missing/private`
hence there is no simple way to skip private elements from doclint.
Therefore we check javadoc using the Eclipse Java compiler
(which is used by default) and javadoc configuration in
`.settings/org.eclipse.jdt.core.prefs` files.
This allows more fine grained configuration.
We can reconsider this when javadoc starts supporting access specifiers
in the doclint configuration.
Below are detailled explanations for most modifications.
@inheritDoc
===========
doclint complains about explicits `{@inheritDoc}` when the parent does
not have any documentation. As far as I can tell, javadoc defaults to
inherit comments and should only be used when one wants to append extra
documentation from the parent. Given the parent has no documentation,
remove those usages which doclint complains about.
In some case I have moved up the documentation from the concrete class
up to the abstract class.
Remove `{@inheritDoc}` on overriden methods which don't add additional
documentation since javadoc defaults to inherit javadoc of overridden
methods.
@value to @link
===============
In PackConfig, DEFAULT_SEARCH_FOR_REUSE_TIMEOUT and similar are forged
from Integer.MAX_VALUE and are thus not considered constants (I guess
cause the value would depends on the platform). Replace it with a link
to `Integer.MAX_VALUE`.
In `StringUtils.toBoolean`, @value was used to refer to the
`stringValue` parameter. I have replaced it with `{@code stringValue}`.
{@link <url>} to <a>
====================
@link does not support being given an external URL. Replaces them with
HTML `<a>`.
@since: being invalid
=====================
org.eclipse.jgit/src/org/eclipse/jgit/util/Equality.java has an invalid
tag `@since: ` due to the extra `:`. Javadoc does not complain about it
with version 11.0.18+10 but does with 11.0.19.7. It is invalid
regardless.
invalid HTML syntax
===================
- javadoc doesn't allow <br/>, <p/> and </p> anymore, use <br> and <p>
instead
- replace <tt>code</tt> by {@code code}
- <table> tags don't allow summary attribute, specify caption as
<caption>caption</caption> to fix this
doclint visibility issue
========================
In the private abstract classes `BaseDirCacheEditor` and
`BasePackConnection` links to other methods in the abstract class are
inherited in the public subclasses but doclint gets confused and
considers them unreachable. The HTML documentation for the sub classes
shows the relative links in the sub classes, so it is all correct. It
must be a bug somewhere in javadoc.
Mute those warnings with: @SuppressWarnings("doclint:missing")
Misc
====
Replace `<` and `>` with HTML encoded entities (`< and `>`).
In `SshConstants` I went enclosing a serie of -> arrows in @literal.
Additional tags
===============
Configure maven-javad0c-plugin to allow the following additional tags
defined in https://openjdk.org/jeps/8068562:
- apiNote
- implSpec
- implNote
Missing javadoc
===============
Add missing @params and descriptions
