The basic conf(based on the samples of Kotlin-DSL) of the plugin would be: The complete example is here: } Without further scrolling below the code snippet by applying the above theoretical knowledge guess the output from the code like the sequence of print statement executed. } Coroutines provide us an easy way to do synchronous and asynchronous programming. We need to add lifecycle-viewmodel-ktx dependency to the module-level build.gradle to access these custom scopes, Lets check the below code how to create the scope and launch coroutine and cancel when the component is destroying, Basically, CoroutineScope takes CoroutineContext as an argument. // dependency to platform part of ktor-client will be added automatically We need to take care of exceptions and handle them with try/catch or by providing CoroutineExceptionHandler. Problem comes when I'm trying to use the Plugin in another project, I'm getting: On Android, coroutines help to manage long-running tasks that might otherwise block the main thread and cause your app . If we use a normal Job instance when there was an exception in any child other than CancellationException it cancels the parent as well as other children. androidMain { import kotlinx.coroutines android. } Should I shadow Kotlin when writing a Gradle Plugin, Error with Building Fatjar Using Kotlin DSL, Kotlin DSL build scripts dependency updates, Gradle project builds successfully but IntelliJ cannot resolve references, Apply Kotlin multiplatform plugin via gradle legacy plugin application, Project 'fatjar' not found in root project. You can connect one multiplatform project to another as a dependency. Have a look at the below code where GlobalScope.launch creates and launches a coroutine because suspend functions cant be called directly in normal functions. sourceSets { implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core-jvm:1.6.4' Once I apply the Shadow Plugin the jar is about 62Mb, even applying minimize size of the jar is 12MB. You cannot set dependencies on platform-specific libraries in the common source set. Scopes help to predict the lifecycle of the coroutines. implementation("com.squareup.sqldelight:native-driver:1.5.3") dependencies { Apache 2.0. } As coroutines are still considered an experimental feature in the current version of Kotlin (version 1.2.30 at the time of writing), you will need to add the following line to your gradle.properties, otherwise you'll see a warning in the compiler output.
