Buck changed export_deps from a boolean to be exported_deps, a list of
dependencies that are to be added to deps and also exported. This
allows libraries to have dependencies for implementation use only, but
not expose them to callers for linkage.
exported_deps aren't transparently transitive anymore. This mostly
impacts the plugin-api:lib rule.
This is the first time Gerrit is using upstream Buck with no patches.
- Java memory settings for Buck can now be supplied in a project
specific file using `.buckjavaargs` in the root directory. The file
replaces the `.buckrc` previously supported by Gerrit's fork.
- Temporary directories for java_application() invoked from genrule()
is now supplied as part of the arguments using $TMP. This removes
one of the patches Gerrit had for Buck.
- Unit tests use the system temporary directory during testing. This
can be faster if the temporary directory is a tmpfs. Unfortunately
not all passing tests clean up after themselves, making it possible
to exhaust system memory and swap with useless tmpfs contents.
Using the system temporary directory for tests removes another patch
Gerrit had on top of Buck.

buck build api
generates now javadocs.
buck build api_install
installs all plugin/extension related artifacts with javadocs in the
local Maven repository.

Guice 4.0-beta leaked the maven metadata files for Guava when it was
repacked to a private namespace. This confuses Buck when creating a
combined JAR that has both Guice and Guava.
Guice also leaked the source files for javax.annotation into its
binary JAR files. Buck sometimes finds and extracts these source
files at compile time, creating duplicate versions of the classes.

gerrit-review has been running on roughly this version for
months. Upgrade to the build available in Maven Central.

java_library() targets must now list every dependency they need for
an import. This permits buck to run more targets in parallel as it
has a better view of the dependency graph, and opens the door for
buck to make even more optimizations in the future.

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
