# coroutines

[Bernhard]

calling a ktor client with runBlocking(Dispatchers.Default) { ... } the request fails due to the wrong method type (requires POST instead of GET), but I'm getting an exception that is different than I'd expect:

What am I doing wrong?

[ephemient]

library versions?

[Bernhard]

is this classpath hell?

[ephemient]

almost certainly

[Bernhard]

I see coroutines 1.11.0 and 1.10.2 being pulled in by different kotlin libs

[Bernhard]

ktor logging for instance pulls in 1.10.2

[ephemient]

then you should only have 1.11.0 in your classpath

[ephemient]

both is a disaster waiting to happen (like this)

[Bernhard]

that's what I want, right
\--- org.jetbrains.kotlinkotlin compiler runner2.4.10
+--- org.jetbrains.kotlinkotlin daemon client2.4.10
\--- org.jetbrains.kotlinxkotlinx coroutines core jvm1.8.0 -> 1.11.0 (*)

[Bernhard]

and I suppose this is the issue

migrationTestCompileClasspath - Compile classpath for 'migrationTest'.
+--- org.jetbrains.kotlin:kotlin-stdlib:2.4.10
|    \--- org.jetbrains:annotations:13.0 -> 23.0.0
+--- at.fyayc:emporix-api-client -> project ':api-client'
|    +--- io.ktor:ktor-serialization-kotlinx-json:3.5.2
|    |    \--- io.ktor:ktor-serialization-kotlinx-json-jvm:3.5.2
|    |         +--- org.slf4j:slf4j-api:2.0.18
|    |         +--- org.jetbrains.kotlinx:kotlinx-coroutines-core:1.11.0
|    |         |    \--- org.jetbrains.kotlinx:kotlinx-coroutines-core-jvm:1.11.0 -> 1.10.2
|    |         |         +--- org.jetbrains:annotations:23.0.0

[ephemient]

that's Gradle doing the right thing by default, yes. latest of all requested versions

[Bernhard]

1.11.0 -> 1.10.2

[Bernhard]

even that one?

[ephemient]

oh that's not

[ephemient]

1.8.0 -> 1.11.0 is 👍

[ephemient]

1.11.0 -> 1.10.2 is 👎

[Bernhard]

I fear it might be the spring boot dependency plugin forcing this in

[Bernhard]

yep, that was it

[Bernhard]

had to downgrade coroutines and ktor client
