Missing import of `symlink` from the `os` module causes an error:
Traceback (most recent call last):
File "/work/gerrit/tools/download_jar.py", line 108, in <module>
symlink(cache_ent, args.o)
NameError: name 'symlink' is not defined

Developers may now request buck to use a local mirror by setting
the URL into local.properties, a file already ignored under the
current buck build process, e.g.:
download.GERRIT = http://nexus.my-company.com/
download.MAVEN_CENTRAL = http://nexus.my-company.com/
To support this usage buck now passes to download_jar.py only the name
of the repository in the URL. download_jar parses local.properties
(if present) and replaces the "MAVEN_CENTRAL:" prefix with the URL
supplied by the user.
Because the URL can vary cache entries in buck-cache are now using the
SHA-1 we expect/verify against, instead of the SHA-1 of the URL. This
makes it easier to find a specific JAR in the cache. The artifact,
version and SHA-1 as named in the maven_jar() rule are the strings
used in the file name in buck-cache.
If no SHA-1 verification happens (e.g. source attachment JARs that
are not included into the build) then sha1(canonical_url) is used.
Here the canonical URL uses the repository id prefix string, e.g.:
MAVEN_CENTRAL:org/apache/mina/mina-core/2.0.5/mina-core-2.0.5-sources.jar

This option should permit curl to pick up proxy authentication
information from ~/.netrc rather than requiring it to be embedded into
the http_proxy environment variable. This is important on shared user
systems where the environment of a process is typically readable by
any user, while ~/.netrc is usually set with a mode 0600.

* Mostly involves changing print to be a function, and adding
"from __future__ import print_function" for copatibility.

When the build is downloading a lot of dependency JARs, there is
no output on the console.
Print the URL of the file that is being downloaded.

When calling curl with check_call, CalledProcessError can be
raised. Catch it to avoid an ugly python traceback in the build
log.

Implement a new build system using Buck[1], Facebook's
open source clone of Google's internal build system.
Pros:
- Concise build language
- Test and build output is concise
- Test failures and stack traces show on terminal
- Reliable incrementals; clean is unnecessary
- Extensible with simple blocks of Python
- Fast
buck: clean: 0.452s, full 1m21.083s [*], no-op: 7.145s,
mvn: clean: 4.596s, full 2m53.776s, no-op: 59.108s,
[*] full build includes downloading all dependencies,
time can vary due to remote server performance.
Cons:
- No Windows support
- No native Maven Central support (added by macros)
- No native GWT, Prolog, or WAR support (added by macros)
- Bootstrap of buck requires Ant
Getting started:
git clone https://gerrit.googlesource.com/buck
cd buck
ant
Mac OS X:
PATH="`pwd`/bin:/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands:$PATH"
Linux:
PATH="`pwd`/bin:$PATH"
Importing into Eclipse:
$ time buck build :eclipse
0m48.949s
Import existing project from `pwd`
Import 'gerrit' (do not import other Maven based projects)
Expand 'gerrit'
Right click 'buck-out' > Properties
Under Attributes check 'Derived'
If the code doesn't currently compile but an updated classpath
is needed, refresh the configs and obtain missing JARs:
$ buck build :eclipse_project :download
Running JUnit tests:
$ time buck test --all -e slow # skip slow tests
0m19.320s
$ time buck test --all # includes acceptance tests
5m17.517s
Building WAR:
$ buck build :gerrit
$ java -jar buck-out/gen/gerrit.war
Building release:
$ buck test --all && buck build :api :release
$ java -jar buck-out/gen/release.war
$ ls -lh buck-out/gen/{extension,plugin}-api.jar
Downloading dependencies:
Dependencies are normally downloaded automatically, but Buck can
inspect its graph and download missing dependencies so future
compiles can run without the network:
$ buck build :download
