Hello everyone, can someone tell me what's wrong why coroutines doesn't work?

Did you add the coroutines library (

kotlinx-coroutines-core

) to your build script (

build.gradle.kts

)?

where should I put?

You should add the coordinates of the coroutines library in the

dependencies { ... }

block. Something like:

dependencies {
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.7.3")
    testImplementation(kotlin("test"))
}

If you look it up, you will find the kotlinx.coroutines repository, and there are instructions on how to add the dependency: https://github.com/Kotlin/kotlinx.coroutines#gradle (This is the case for any well-documented library) This is where you can find the coordinates in the form

groupId:artifactId:version

. For coroutines 1.7.3, the coordinates are

org.jetbrains.kotlinx:kotlinx-coroutines-core:1.7.3

. This is why we add the line

implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.7.3")

.

Thank you for your help! Highly appreciated!💯
