v0.51.0

Enhancements

• Generates proguard artifact correctly for proguard version > 7 which uses a different package name (#914)
• Only creates manifest merger target if the project has an android app or library (#919)
  • This removes the need to download android artifacts when building in a pure java repository.
• Supports gradle version 5.x, 6.x (#879)
• Supports android gradle plugin version 3.6.1 (#905)
• Kotlin version updated to 1.3.72 (#905)
• Use kotlin compiler zip (https://github.com/JetBrains/kotlin/releases/tag/v1.3.72) to build kotlin modules. (#922)
• Updated to latest buck version (#922)
• Faster resolution when using versioned deps and resolving 3rdparty deps only (#920)

// okbuck config
okbuck {
    externalDependencies {
        // enables exported deps resolution
        enableExportedDeps = true
        // only resolves third party deps
        thirdPartyResolutionOnly = true
   }
}

// settings.gradle
include ":tooling:gradle"
include ":tooling:gradle:dummy1"
include ":tooling:gradle:dummy2"
include ":tooling:gradle:dummy3"
include ":tooling:gradle:dummy4"
include ":tooling:gradle:dummy5"

// Add a simple build.gradle file to each dummy project
apply plugin: "java"

// Now the above setup will make a total of 8 projects available to gradle 
// (root-project, :tooling, and the ones defined explicitly) which will be 
// able to parallelize resolving configurations on up to 8 threads.

• Error-prone and other 3rdparty deps has been updated (#879)

Potential Breaking Changes

• Buck requires python 3.7.x or up to run.
• Install watchman or remove watchman as the glob handler from .buckconfig. Otherwise, the build will fail.

// remove these configs
[project]
    glob_handler = watchman
    build_file_search_method = watchman

• Kotlin version is not automatically detected from the classpath. Default is set to 1.3.72 but you can change it as below

okbuck {
  kotlin {
    version = "1.3.61"
    // You can run ./buckw build .okbuck/workspace/kotlin_home: and 
    // check the error to get the sha256 when changing version.
    compilerZipSha256 = "3901151ad5d94798a268d1771c6c0b7e305a608c2889fc98a674802500597b1c" 
  }
}

• extraDepCaches has been removed. Use extraDepCachesMap instead.

// Additional dependency caches. Every value "entry" will create a new configuration
// "entryExtraDepCache" that can be used to fetch and cache dependencies. the boolean defines
// weather a prebuilt rule needs to be skipped or not. { "tools": true } skips prebuilt rule for
// all tools dependencies. 
extraDepCachesMap << [tools:false]

Bug Fixes

• Kotlin Home is downloaded and set correctly as part of buckw run. (#915)
  • Please run ./gradlew buckwrapper to get the latest version of buckw wrapper
  • This step in buckw can be removed once buck natively supports source path for kotlin home (facebook/buck#2121 (comment))
• Resolved transformed artifacts from transofrm-2 is not included when running with gradle 5.x (#916) (fixes #873)
