Description of this change

This change gets the kotlin version from rules_kotlin (commit 242 - bazelbuild/rules_kotlin@a3d4d56) and updates the ide_info such that Kotlin 1.3 functionality can be accessed if compiled with Kotlin 1.3

[brendandouglas]

Thanks, we can apply this upstream. It should go in aspect/intellij_info.bzl instead, as it's bazel-specific (doesn't apply to our internal build system, which has different kotlin rules)

@brendandouglas Does that mean you will apply the change or should I change the PR?

[szinn]

retest this please

@brendandouglas Any movement on this PR?

[cgruber]

Please can we get some eyes on this (@jin maybe?) Someone? We're nearly at Kotlin 1.4, and we still have the IDE re-configured to be at 1.2 every time we sync. The kotlin rules are passing the information and this PR scoops that up and properly sets the language level. This is critical to a decent user experience.

@brendandouglas is this good for import? and could we use the internal copybara script to import this, or has that diverged or bit rotted?

[DrewKiino]

bump - can we get this landed?

[szinn]

Bump again @brendandouglas @jin

I'm so glad this is in. I'm having a heck of a time with coroutines. Thanks @jin !!
