I keep getting the following error when adding implementation group: "org.http4k", name: "http4k-graphql", version: "3.278.0" to my build.gradle file. Any ideas?

Could not find org.http4k:http4k-format-jackson:3.278.0.

[dave]

we need to sync it to maven - can you add jcenter in the meantime?

[Arnab Datta]

Yeah, that works

[dave]

the maven central syncing is really flakey -- not us but sontatype... 🙄

[Arnab Datta]

Somewhat related: https://www.http4k.org/guide/modules/graphql/
references something from com.expediagroup What version are you actually using in the example? Do you know? I couldn’t find any references to the version that is used in the example repo

[dave]

aha - sorry

[dave]

we use the expedia kotlin lib

[dave]

i'll update it, but check out the example: https://github.com/http4k/examples/tree/master/graphql

[Arnab Datta]

Yes, but which version? 😛

[Arnab Datta]

Ah yes ok. Found it now.

[Arnab Datta]

Just fyi, version 4.0.0 breaks your example.

[dave]

ah - thanks for letting us know. will check it out

[Arnab Datta]

Nw

Last question: Getting the following for this line of code from your example

val gql: GraphQLHandler = JavaHttpClient().asGraphQLHandler(Uri.of("<http://localhost:8000/graphql>"))

Cannot access class 'java.net.http.HttpClient'. Check your module classpath for missing or conflicting dependencies

[Arnab Datta]

Is there a conflicting import somewhere maybe? Or a conflict in dependencies?

[dave]

are you on Java 8? if so, use Java8HttpClient

[dave]

also - how does it break the example?

[Arnab Datta]

Aha, yes. Java 8, sadly.

[Arnab Datta]

On 4.0.0, there isn’t any export that is import com.expediagroup.graphql.SchemaGeneratorConfig

[Arnab Datta]

I don’t know exactly where that import will be changed, but I know that it isn’t there anymore

[Arnab Datta]

Same goes for import com.expediagroup.graphql.toSchema

[dave]

?

[dave]

[dave]

are you on a non-alpha version?

[Arnab Datta]

No, that was the same version I tested…or atleast thought I tested. Strange.

[Arnab Datta]

Literally just tried again, and now it works. No clue why it didn’t work before.

[dave]

lol. ok

[Arnab Datta]

Severe case of pebcak I suspect 😂
