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
