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

This ensures the compiler compiles against the public, supported and
documented API for a specific VM version (here 11) [1]. This also means
that
we don't need EE descriptors in Eclipse anymore in order to ensure that
only supported APIs of the selected Java version can be used.
According to [2] if option --release is used --source and --target
options can't be used.
While we are at it also add default value for all new jdt core options
added in Eclipse 4.21.

Different archive formats support a compression level in the range
[0-9]. The value 0 is for lowest compressions and 9 for highest. Highest
levels produce output files of smaller sizes but require more memory to
do the compression.
This change allows passing a "compression-level" option to the git
archive command and implements using it for different file formats.

Since [1] the gerrit project includes jgit as a submodule, and has this
warning enabled, resulting in 100s of warnings in the console.
Also enable the warning here, and fix them.
At the same time, add missing braces around adjacent and nearby one-line
blocks.

The code base has several @SuppressWarnings annotations to suppress
warnings raised by Error Prone, but those are not recognized by
Eclipse and there is currently no way to tell it about them [1].
Suppress them for now.

The commit message template contains a superfluous blank at the end of
the first line, which is deleted by this change. This is only relevant
for jgit contributors using Eclipse, not for jgit users.

Do not automatically organize imports using a save action since this
seems to be buggy and removed some annotations org.eclipse.jgit.pgm
needs to use args4j.

Revert the following save actions which were introduced in c0ad77d8:
- always use braces around blocks
- remove unused imports
Other than I expected save actions are run globally on edited files -
and not only on edited code lines only.
Hence revert the save action "Convert control statement bodies to
blocks" which would affect a large number of code lines not affected by
the change editing some small part of a class. This would generate a
large number of changes which may lead to many unnecessary conflicts.
Total number of affected lines across jgit would be around 10k lines.
Also revert "Remove unused imports" since it erroneously removes imports
of some annotations needed by pgm classes using args4j.

Add the following Eclipse save actions executed when saving modified
lines. This should help to reduce manual work needed to maintain a clean
and consistent code style:
- organize imports
- always use braces around blocks
- add missing annotations
- @Override including implementation of interface methods
- @Deprecated
- remove
- unused imports
- unnecessary $NON-NLS$ tags
- redundant type arguments
Also add default values for new settings that were introduced in recent
Eclipse versions up to Neon since we updated save rules the last time.

Since the introduction of generic type parameter inference in Java 7,
it's not necessary to explicitly specify the type of generic parameters.
Enable the warning in Eclipse, and fix all occurrences.

Set missingOverrideAnnotation=warning in Eclipse compiler preferences
which enables the warning:
The method <method> of type <type> should be tagged with @Override
since it actually overrides a superclass method
Justification for this warning is described in:
http://stackoverflow.com/a/94411/381622
Enabling this causes in excess of 1000 warnings across the entire
code-base. They are very easy to fix automatically with Eclipse's
"Quick Fix" tool.
Fix all of them except 2 which cause compilation failure when the
project is built with mvn; add TODO comments on those for further
investigation.

Update the project-specific Eclipse settings to replace the use of the
org.eclipse.jdt.annotation.Nullable class the new JGit-specific
@Nullable annotation. I verified that Eclipse reports errors when the
return value of a method annotated with
@org.eclipse.jgit.annotations.Nullable is dereferenced without a null
check.
Also remove the Maven and MANIFEST.MF dependencies on
org.eclipse.jdt.annotation.
Eclipse null analysis uses three annotations: @Nullable, @NonNull and
@NonNullByDefault. All three are updated in this patch because it is
invalid to set the Eclipse preferences to empty values. So far only
@Nullable has been introduced in org.eclipse.jgit.annotations.
My personal preference is to follow the advice in Effective Java and
avoid the null-return idiom, and to avoid passing null values in
general. This sets the expectation is that arguments and return types
are assumed non-null unless otherwise documented. If that is the
expectation, then consistent application of @NonNull is redundant and
hurts readability by cluttering the code, obscuring the occasional
@Nullable annotation that really requires attention.
If the JGit community decides there is value in using the @NonNull and
@NonNullByDefault annotations we can add them--this change configures
Eclipse to use them.

Allow use of ArchiveCommand without depending on the jgit command-line
tools.
To avoid complicating the process of installing and upgrading JGit,
this does not add a dependency by the org.eclipse.jgit bundle on
commons-compress. Instead, the caller is responsible for registering
any formats they want to use by calling ArchiveCommand.registerFormat.
This patch puts functionality that requires an archiver into a
separate org.eclipse.jgit.archive bundle for people who want it. One
can use it by calling ArchiveCommand.registerFormat directly to
register its formats or by relying on OSGi class loading to load
org.eclipse.jgit.archive.FormatActivator, which takes care of
registration automatically.
Once the appropriate formats are registered, you can make a tar or zip
from a git tree object as follows:
ArchiveCommand cmd = git.archive();
try {
cmd.setTree(tree).setFormat(fmt).setOutputStream(out).call();
} finally {
cmd.release();
}
