Kotlin Rules 1.5.0 (Alpha 3)

Kotlin rules for Bazel - Legacy Rules 1.5.0

Note: These rules are maintained externally by volunteers (with Google's approval)

Note: The "legacy" prefix will be dropped as of this release. These are the rules, from this point on, until and unless Google chooses to externalize internal rules, at which point we can differentiate.

Note: legacy-1.4.0 isn't released, and this release includes all features in that line of development. Many of those changes are included in this list.

Alpha 3 Revisions

• Fixed default option visibility
• Bump to project Kotlin 1.4.20

Alpha 2 Revisions

• JavaBuilder compilation prerelease available for testing using: --define=experimental_use_abi_jars=1
• jdeps automatically generated from kt_jvm_library rules.
• Support for kt_kotlinc_options to kt_jvm_library. Library options supersede toolchain options.
• Added kt_kotlinc_options:

Name	Description	Type	Mandatory	Default
include_stdlibs	Don't automatically include the Kotlin standard libraries into the classpath (stdlib and reflect).	String	optional	"all"
warn	Control warning behaviour.	String	optional	"report"
x_allow_jvm_ir_dependencies	Suppress errors thrown when using dependencies not compiled by the IR backend.	Boolean	optional	False
x_allow_result_return_type	Enable kotlin.Result as a return type	Boolean	optional	False
x_inline_classes	Enable experimental inline classes	Boolean	optional	False
x_jvm_default	Specifies that a JVM default method should be generated for non-abstract Kotlin interface member.	String	optional	"off"
x_no_optimized_callable_references	Do not use optimized callable reference superclasses. Available from 1.4.	Boolean	optional	False
x_skip_prerelease_check	Suppress errors thrown when using pre-release classes.	Boolean	optional	False

Legacy Kotlin Rules 1.3.0

Kotlin rules for Bazel - Legacy Rules 1.3.0

Note: These rules are maintained externally from Google (with Google's oversight and help)

Updates the Kotlin rules for Bazel with a significant set of improvements, including the improvements contained in @cgruber's fork of rules_kotlin which is considered "upstreamed" as of this release.

Notable changes:

• Various to run against modern versions of Bazel (remote deprecated/removed API usages)
• Support for Kotlin 1.3 (cgruber#7)
  • Support custom "repositories" for kotlinc to permit non-default kotlinc versions
  • Support custom toolchains to permit Kotlin and Java language version settings.
    • using with kotlinc < v1.3 now not supported, due to different stdlib/runtime artifact handling, but older language versions allowed with a custom toolchain.
• Fixes to friends/internal handling (#222)
• Use jarjar in the persistent worker, so as not to leak its own deps into the compilation job (cgruber#4)
• Permit full compile-time classpath to be passed to compiler (cgruber#5)
  • This disables the very naive strict-deps implementation, which was based on limiting the classpath, which forced additional declarations of "upstream" jars containing compiler-necessary bytecode such as supertypes). A future effort to add strict deps rooted in proper deps/symbol analysis is needed.
• Quiesce java9+ reflective access warnings (cgruber#15)
• Add exports= to kt_jvm_library() (cgruber#7)
• Add exports= to kt_jvm_import() (cgruber#18) (
• Properly handle java version semantics, to call --multi-release under the right conditions (cgruber#23)
• Fix building on windows (#193)
• Java launcher update (#199)
• Infer test class from test name, by default, in kt_jvm_unit_test() (#209, #257)
• Handle various packaging of javascript deps for kt_js_import() (#223)
• Fix bad jdeps handling (#234 / #235)
• Support jvm targets later than 1.8 (#229 / #236)
• Fix regression where tags were not being propagated through kt_android_library #255

Plus:

• Various cleanups, refactors, examples and tests.
• Various regressions along the way
