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 dependencies to use the JGit-internal @Nullable
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.

Use japicmp instead of clirr to detect API changes
Clirr doesn't support Java 8 hence use japicmp instead.
