# multiplatform

[nestserau]

I’ve started working with ktor HttpClient and ran into a couple of issues. First, is that my IDE doesn’t recognize HttpClient and runBlocking, while the code itself compiles perfectly fine. What could be a reason for that?

[gildor]

Looks as IDE issue, try restart + invalidate caches

Please post your build.gradle

If anyone can spot an error that would be awesome.

[msink]

Well, I don't know, looks sane. Maybe ext.ktor_version = '1.0.+' - better use exact version.

[nestserau]

I tried that and then invalidated cache and restarted. Same thing 😞

[gildor]

I don’t think that it somehow related to build.gradle

[gildor]

Some IDE problem

[gildor]

and most probably related to Gradle Metadata

[nestserau]

Yes, actually when I restart it it throws an exception.

[gildor]

try io.ktor:ktor-client-jvm

[nestserau]

Maybe that’s the reason, ktor-client-jvm hasn’t been updated for a long time. The latest version is 0.9.0-alpha.

[msink]

And maybe it depend on your Gradle version... But if gradle build passed it should be fine.
Strange.

[gildor]

It may be just a problem of Idea with gradle metadata dependencies

[gildor]

runBlocking is actually strange

[msink]

As experiment - if leave only one target - ios or android - it works?

[nestserau]

So I’ve thrown out the android target, invalidated cache and restarted. No change.

[nestserau]

It looks like IntelliJ doesn’t understand the structure of the project completely. Although Gradle itself can build the project just fine. That’s a minor problem to me for now.

[nestserau]

You won’t believe, but I started working on the project further, and somehow it now recognizes HttpClient, just out of the blue, I didn’t change anything, just was typing in more code.

[nestserau]

Aha, now I get it. If I use HttpClient version 1.0.0, then it’s fine. With 1.0.1 it’s red. Problem solved, sort of.
