Build with Buck 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 [1] http://facebook.github.io/buck/ Change-Id: I40853b108bd8e153cefa0896a5280a9a5ff81655
