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 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
