hello :wave: are there any migration guides from 1...

hello 👋 are there any migration guides from 1.3.x -> 1.4/1.5? looks like some of the artifacts got renamed and no longer resolve

[Dariusz Kuc]

looks like in 1.5 artifacts now pull .kotlin_metadata files only, i.e.

api("io.ktor:ktor-client-cio:$ktorVersion")

no longer resolves io.ktor.client.engine.cio.CIO

[Dariusz Kuc]

nvm it was an issue with my local .m2 repo, clearing the cache and redownloading artifacts solved the issue

[crummy]

the maven version of rm -rf node_modules 😆

[Dariusz Kuc]

yeah there seems some issue between intellij and gradle resolving those incorrectly (i.e. I build it locally from command line and it worked -> then Intellij tried to reimport it and blew up)

[Dariusz Kuc]

🤔 unsure what is causing this but there is some issue with my update to Kotlin 1.4 that is blowing up Gradle

[Dariusz Kuc]

hitting the same problem with unable to resolve io/ktor/client/engine/cio/CIO from one of my integration tests that use GradleRunner

[Dariusz Kuc]

https://github.com/ExpediaGroup/graphql-kotlin/pull/1007 -> updates work if I’m using Ktor 1.3.1 but blows up when 1.4 or 1.5 is used

@Dariusz Kuc could you please share the steps to reproduce your problem? I've tried to run tests from GraphQLKtorClientTest using https://github.com/dariuszkuc/graphql-kotlin/tree/lib_updates but they all passed.

[Dariusz Kuc]

sure

[Dariusz Kuc]

1. clone project
2. run ./gradlew clean build from root project dir
3. notice that all graphql-kotlin-gradle-plugin integration tests that use Ktor CIO fail (from test report index.html)

> There was a failure while executing work items
   > A failure occurred while executing com.expediagroup.graphql.plugin.gradle.actions.DownloadSDLAction
      > io/ktor/client/engine/cio/CIO

[Dariusz Kuc]

just did that on a fresh installation of Maven + Gradle (no previous caches)

opening up project in IntelliJ shows following dependencies for the graphql-kotlin-ktor-client

notice that jackson pulls in the jvm artifacts for JSON and core but there is no CIO JVM artifact

[Dariusz Kuc]

updated GH action on the PR to upload build reports on failure -> all the Gradle integration tests that rely on Ktor CIO fail with java.lang.ClassNotFoundException: io.ktor.client.engine.cio.CIO

also note: when running a clean build (with wiped out dependencies) graphql-kotlin-ktor-client module build successfully, but once the build fails on the plugin integration tests then ktor client starts failing on the build as well

[Joe]

does changing dep from ktor-client-cio to ktor-client-cio-jvm help? had to do that when going from 1.3.1 to 1.4.0 in one of my projects

[Dariusz Kuc]

pretty sure it would work but I guess it would made adopting the client on android a little bit harder

[Dariusz Kuc]

*guess it would be resolved once we move the module to multiplatform

[Dariusz Kuc]

my guess there is something between Gradle and Maven that get confused (as clearing just .m2 directory does make it work temporarily)

[Aleksei Tirman [JB]]

I've reproduced it with my sandbox project. Could you please try to build that project? Maybe this problem is related to Gradle cache.

cio-jvm.zip

[Dariusz Kuc]

yes your project doesn't build for me either

[Dariusz Kuc]

it does seem like there is some gradle cache issue

[Dariusz Kuc]

since wiping out local .m2 cache resolves the issue, it is something between gradle and maven that blows up
