IntelliJ IDEA's New Kotlin Coroutine Inspections, Explained | The IntelliJ IDEA Blog

IntelliJ IDEA has introduced new Kotlin coroutine inspections to help developers write cleaner and more efficient code, addressing common issues in codebases that Marcin Moskała, a Kotlin expert, has often encountered. These inspections, available in IntelliJ IDEA 2025.2 and later, aim to guide developers in adopting best practices, such as using `awaitAll()` and `joinAll()` for cleaner and more efficient task handling, employing `currentCoroutineContext()` instead of `coroutineContext` to avoid context mismanagement, and avoiding `runBlocking` inside suspending functions to prevent thread blocking. The inspections also discourage using `Job` as an argument in coroutine starters due to its potential to disrupt structured concurrency, advise using `suspendCancellableCoroutine` over `suspendCoroutine` for better cancellation support, and highlight the importance of scope management to prevent memory leaks. Additionally, the IDE suggests simpler operations for flow processing, like `mapNotNull`, enhancing the core development experience by making correct usage more intuitive while mitigating common pitfalls.
