Overview

Buck

Buck is a build tool. To see what Buck can do for you, check out the documentation at http://buck.build/.

Installation

Since Buck is used to build Buck, the initial build process involves 2 phases:

1. Clone the Buck repository and bootstrap it with ant:

git clone --depth 1 https://github.com/facebook/buck.git
cd buck
ant

You must be using Java 8 or 11 for this to compile successfully. If you see compilation errors from ant, check your JAVA_HOME is pointing at one of these versions.

2. Use bootstrapped version of Buck to build Buck:

./bin/buck build --show-output buck
# output will contain something like
# //programs:buck buck-out/gen/programs/buck.pex
buck-out/gen/programs/buck.pex --help

Prebuilt buck binaries

Pre-built binaries of buck for any buck sha can be downloaded from https://jitpack.io/com/github/facebook/buck/<sha>/buck-<sha>.pex. The very first time a version of buck is requested, it is built via jitpack. As a result, it could take a few minutes for this initial binary to become available. Every subsequent request will just serve the built artifact directly. This functionality is available for any fork of buck as well, so you can fetch https://jitpack.io/com/github/<github-user-or-org>/buck/<sha>/buck-<sha>.pex

For buck binaries built for JDK 11, modify end of the url to buck-<sha>-java11.pex.

Feature Deprecation

Buck tries to move fast with respect to its internals. However, for user facing features (build rules, command line interface, etc), the Buck team tries to have a graceful deprecation process. Note that this generally applies only to documented functionality, or functionality that is less documented, but appears to be in wide use. That process is:

An issue is opened on Github suggesting what will be deprecated, and when it will be removed. For larger features that are deprecated, there may be a period when the default is the new setting, and the old behavior may only be used with a configuration change.
- In-progress deprecation issues are tagged with 'announcement' and 'deprecation'
A change is submitted to Buck that puts the old behavior behind a configuration flag and sets the default to the old behavior. These flags can be found at https://buck.build/concept/buckconfig.html#incompatible.
For larger features, a change eventually is put in place that sets the default to the new behavior. e.g. when Skylark becomes the default build file parser.
When the removal date is reached, a change is submitted to remove the feature. At this point, the configuration value will still parse, but will not be used by Buck internally.

Add support for error prone as native compiler option
Fixes #994.

Summary: http://errorprone.info is a static analysis tool for Java that catches common programming mistakes at compile-time. With this change it can be permanenty or instantly activated as default compiler. Moreover, java_library rule is extended as well.

The configuration option: java.error_prone_javac is considered to be experimental and is not documented.

Test Plan:

Permanently activate error prone: add this line to .buckconfig:

[java] error_prone_javac = true

Instantly activate error prone:

$ buck build --config java.error_prone_javac=true <rule>

Activate error prone per rule base:

java_library( name = 'foo', error_prone_javac = True, [...]

RFC: Introduce build rules for building GWT applications.
I'm looking into adding build rules for building GWT applications. I'm curious what folks think the arguments to the rules should look like.

Do we need a special gwt_library() rule, or can we just use java_library()? My intuition is that if you use JSNI in your Java code, then you need to classify that as a gwt_library().

How do you deal with dependencies that have dual implementations: one for the JRE and one for JavaScript? For example, you may have a subgraph of dependencies that transitively depend on Guava. Then at the top, you have a gwt_binary() target and a java_binary() target? How do you ensure that the gwt_binary() pulls in guava-gwt-17.0.jar while the java_binary() pulls in guava-17.0.jar? One option is to have parallel versions of each subgraph, but that seems messy.

How can we design gwt_binary() (or this whole system of rules) so that it is easy to run the GWT app in developer mode? Ideally, a developer should not have to run buck build after every code modification in order to reload the GWT app. The existing edit-refresh-test cycle needs to be preserved.

[IntelliJ] Handle resources_root in project generation

IntelliJ project generation right now doesn't generate resource folders for Java code, instead relying directly on the generation of source folders. This results in resources being put in the wrong places if resources_root is different from the Java src_roots option. This change introduces a new type of IjFolder (JavaResourceFolder) which tracks resources_root if it is set and sets the relativeOutputPath of the IntelliJ folders to try and handle this correctly.

Note that it probably can't be fully handled correctly if there are source files and resource files mixed in the same directories, because IntelliJ's granularity only goes to the directory level, while buck can set them at the file level.

I'm not entirely sure if this is the best approach to handling this, would appreciate any suggestions

Filtering platform specific source files

This PR fixes #1701

Known issue:

srcs=['.'] will crash on go_binary rules but not on go_library. The crash happens before GoCompile.getBuildSteps gets called. Temporary workaround is to use srcs=glob(["*.go"]). The filtering still works.

Update manifest merger

This switches to ManifestMerger2 implementation and fixes https://github.com/facebook/buck/issues/299

Majority of this PR is updating aosp to 25.2.0 version of the tools.

The only interesting change is in GenerateManifestStep.java.

For the sake of not maintaining two versions of aosp, this PR replaces old ManifestMerger with ManifestMerger2. Having both is possible (we could take ManifestMerger from tools 24.x.x, the last version that shipped with it) but if the new merger works for everyone, probably best to just go with that.

Parallelize swift compilation by compiling file individually

This PR is one of the effort to rework the incremental build support https://github.com/facebook/buck/pull/907.

Instead of compiling all swift files in a target in one shot, we create build rule for each of the file so that we can compile them in parallel, therefore speed up the compilation process, especially useful for a target with a lot of swift files.

Cross-cell: Fix file system mismatch in classpath resolution

Rule can be provided from different cell and thus output file name must be relocated according to cell root. Change all the methods on JavaLibraryClasspathProvider that take Optional outputJar to take Optional outputJar instead.

SourcePaths are much safer because they encapsulate the project filesystem. That way we know they can always be resolved correctly.

Closes #545

TEST PLAN:

Clone JGit with this patch: [1]. Clone Gerrit Code Review with this patch: [2]. Replace JGit cell during Gerrit build, with:

$ buck build --config repositories.jgit=../jgit gerrit

Observe, that without this diff, the classpath contains invalid entries: non relocated jgit output file. This diff relocates it to jgit cell.

buck fetch fails with symbolic links in an archive

I am trying to add ldap as a dependency using http_archive but buck fails to fetch the library. There is a "broken link" symbolic link in the tests folder which causes buck to fail on sha verification. Is there a way to skip that verification for that specific folder? I am okay to delete that specific folder before verification as well but not sure how.

http_archive(
  name = 'libopenldap-src',
  urls = ['https://www.openldap.org/software/download/OpenLDAP/openldap-release/openldap-2.5.13.tgz'],

I've tried compiling with java 8, 11 and 18... 8 and 11 pass, although when trying to build buck with java 8 it says:

Warning: JAVA_HOME is set to "/Library/Java/JavaVirtualMachines/jdk1.8.0_341.jdk/Contents/Home", which looks like a Java 8 path, but Buck requires Java 11. Ignoring JAVA_HOME. Set BUCK_RESPECT_JAVA_HOME to 1 to disable this behavior.

ant command fails when using java 18 with the following:

Create buck_tool.py

Setting argv[0] to "buck" on Windows violates the normal convention where argv[0] should be the application name. This might convenient for finding buck-related tasks in process-explorer but it comes with the drawback of making argv[0] not reliable for process identification

Update sqlite to include ability to build buck on M1 chips. Currently, BUCK fails because sqlite-jdbc-3.20.0 doesn't support aarch64 but 3.39.2.0 does.
