+        JDK_9="path to JDK 9"
 
-For local development, if you're not working on bytecode generation or the standard library, it's OK to avoid installing JDK 1.6 and JDK 1.7.
-Add `kotlin.build.isObsoleteJdkOverrideEnabled=true` to the `local.properties` file, so build will only use JDK 1.8+. Note, that in this
-case, build will have Gradle remote build cache misses for some tasks. 
+For local development, if you're not working on bytecode generation or the standard library, it's OK to have only JDK 1.8 and JDK 9 installed, and to point `JDK_16` and `JDK_17` environment variables to your JDK 1.8 installation.
+
+You also can use [Gradle properties](https://docs.gradle.org/current/userguide/build_environment.html#sec:gradle_configuration_properties) to setup `JDK_*` variables.
