Legacy Kotlin Rules 1.3.0 (Release Candidate 2)

Kotlin rules for Bazel - Legacy Rules 1.3.0

(Release Candidate 2)

Note: These rules are provisionally released with community support, while Google works to "externalize"
their internal kotlin rules. Support will be best-effort during this phase.

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)
• Handle various packaging of javascript deps for kt_js_import() (#223)
• Fix bad jdeps handling (#234 / #235)

Plus:

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