what can I do if the `compileKotlin` Gradle task always hang kotlinlang #gradle

Gradle task always hangs for 10+ minutes, and launches a Java process that takes up 100% CPU? This is for a small v1.8.10 project with ~10 Kotlin classes (Gradle 8.0.2) I’ve tried cleaning, rebooting, running with

--no-build-cache

--no-configuration-cache

kotlin.incremental=false

, `kotlin.caching.enabled=false`…

Does build finish?

these are the tasks that hang

build.log

I haven’t tried to let it finish, I always quit early. An hour ago it took seconds to compile,

please try to take a look into Kotlin daemon logs inside

<tmp>

directory. For example

/tmp/kotlin-daemon.2023.*.log

there’s nothing in the root

/tmp

dir

Try via

jps -v

also could you try to run the build with Kotlin 1.8.20?

oh, it’s working now

BUILD SUCCESSFUL in 24s

yeah it’s just working, just like before :magic_wand:

oh interesting… it compiles when I comment out everything in the main method. But when I revert it, it stops compiling

here’s a very quick overview of what’s failing to compile.

main.kt

possibly caused by a

while(true) {}

after a suspending function?

it doesn’t seem to occur in 1.8.20, but it does in 1.8.10. I’ve made a YouTrack issue just in case: https://youtrack.jetbrains.com/issue/KT-57744

nice one, that looks the same

Build stuck for several hours (seems to be stuck infinitely)

Stuck for hours! That poor dev…
