What's the difference between

getKotlinPluginVersion

and

kotlinToolingVersion

?

it looks like one is cached in a Gradle extra property and the other is computed anew each time https://github.com/JetBrains/kotlin/blob/bcf27812cd28041e0b9ffa3bfe52fc58c397d0eb/libraries/tools/kotlin-gradle-plugin/src/common/kotlin/org/jetbrains/kotlin/gradle/plugin/KotlinPluginWrapper.kt#L385-L399 they should return the same value though https://github.com/JetBrains/kotlin/blob/bcf27812cd28041e0b9ffa3bfe52fc58c397d0eb/libraries/tools/kotlin-gradle-plugin/src/functionalTest/kotlin/org/jetbrains/kotlin/gradle/unitTests/KotlinToolingVersionTest.kt#L25-L30
