Today there are plenty of modern build tool systems available in the
wild (in no particular order):
* http://bazel.io
* https://pantsbuild.github.io
* http://shakebuild.com
* https://ninja-build.org
* https://buckbuild.com
The attributes, that all these build tools have in common, are:
* reliable
* correct
* very fast
* reproducible
It must not always be the other build tool, this project is currently
using. Or, quoting Gerrit Code Review maintainer here:
"Friends, don't let friends use <the other build tool system>!"
This change is non-complete implementation of JGit build in Buck,
needed by Gerrit Code Review to replace its dependency with standlone
JGit cell. This is very useful when a developer is working on both
projects and is trying to integrate changes made in JGit in Gerrit.
The supported workflow is:
$ cd jgit
$ emacs <hack>
$ cd ../gerrit
$ buck build --config repositories.jgit=../jgit gerrit
With --config repositories.jgit=../jgit jgit cell is routed through
JGit development tree.
To build jgit, issue:
$ buck build //:jgit
[-] PROCESSING BUCK FILES...FINISHED 0,0s
Yes, you can't measure no-op build time, given that Buck daemon is
used.

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.

Current ArchiveCommand design doesn't allow to pass in options to
underlying stream implementations. To overcome this, client has to
implement custom format implementation (it cannot be derived from
the existing one, because the classes are marked as final), and set
the options using ThreadLocal, before the method
ArchiveOutputStream createArchiveOutputStream(OutputStream s)
is get called.
This change extends the ArchiveCommand.Format by allowing to pass
option map during creation of ArchiveOutputStream.
ArchiveCommand is extended correspondingly. That way client can
easily pass options to the underlying streams:
Map<String, Object> level = ImmutableMap.<String, Object> of(
"level", new Integer(9));
new ArchiveCommand(repo)
.setFormat("zip")
.setFormatOptions(level)
.setTree(tree)
.setPaths(paths)
.setPrefix(prefix)
.setOutputStream(sidebandOut)
.call();

Entries for directories are optional and mostly wasted space in most
archive formats (except as a place to hang ownership and filesystem
permissions), but "git archive" includes them. Follow suit.
This will make it easier in a later change to include empty
directories as placeholders for missing submodules.

Introduce a setFilename() method for ArchiveCommand so callers can
specify the intended filename of the produced archive. If the
filename ends with .tar, the format will default to tar; if .zip, zip;
if .tar.gz, gzip-compressed tar; and so on.
This doesn't affect "jgit archive" because it doesn't support the
--output=<file> option yet. A later patch might do that.

That's because the default longFileMode is LONGFILE_ERROR, which
throws an exception for filenames longer than 100 characters. Switch
to LONGFILE_POSIX. While at it, handle large files and filenames with
strange encodings, too.
This requires commons compress 1.4, which introduced support for large
files and POSIX long filenames.

While at it, build a list of registered formats at start() time, so
stop() doesn't have to repeat the same list of formats.

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();
}
