JettyDaemon invokes buck build to ensure GWT JS is up-to-date before
running the server. To be completely compatible with the command line
build it uses the same PATH environment variable, ignoring the PATH
that is inherited from Eclipse.
Including the PATH as part of the genrule() command ensures buck will
rewrite the properties file anytime the user modifies the PATH, rather
than only when there are updates to GWT Java sources.
Using a properties file frees us from worrying about double quoting in
shell: once in the genrule, again in the script itself.
Using a single properties file ensures any GWT UI can be computed or
verified by JettyDaemon. This change simplifies bootstrap for a
developer as they no longer need to build the UI before launching the
server from within Eclipse. JettyDaemon now takes care of it.

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

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
