Redundant label

Reports redundant labels which cause compilation errors since Kotlin 1.4.

Since Kotlin 1.0, one can mark any statement with a label:

fun foo() { L1@ val x = L2@bar() }

However, these labels can be referenced only in a limited number of ways:

  • break / continue from a loop

  • non-local return from an inline lambda or inline anonymous function

Such labels are prohibited since Kotlin 1.4.

This inspection only reports if the Kotlin language level of the project or module is 1.4 or higher.
