# gradle

The new Gradle instructions from the Kotlin 1.8.0 release don't work when trying to use the new compiler options:
https://kotlinlang.org/docs/whatsnew18.html#exposing-kotlin-compiler-options-as-gradle-lazy-properties

This line:
tasks.named("compileKotlin", org.jetbrains.kotlin.gradle.tasks.KotlinJvmCompile::class.java) {

generates this error when refreshing Gradle:
Task with name 'compileKotlin' not found in project...

I was able to get around it by switching that line with this:
tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinJvmCompile::class.java) {

Am I missing something else or are the new instructions incorrect?

don't use allProjects

[ephemient]

if you want to centralize configuration, the recommended path is to write convention plugins

[ephemient]

you are seeing this because your block is running before the plugin is applied

Thanks. If it's an order-of-operations issue, why does it work when I replace tasks.named with tasks.withType?

[ephemient]

because that works even when the task doesn't exist yet

[ephemient]

it applies to any existing and future tasks with type, whereas named adds configuration to an existing task only

[ephemient]

speaking of which, you should also avoid using withType(action) for lazy configuration reasons (it's not, for historical Gradle reasons)

[ephemient]

.withType().configureEach(action) will be lazy if you need

Thanks! I'll look into how to setup convention plugins
