NoClassDefFoundError in gradle task graphqlIntrospectSchema

[huehnerlady]

Hi,

since the update to 4.x.x I am facing the issue that I get an exception in the :graphqlIntrospectSchema task:

Exception in thread "ktor-cio-dispatcher-worker-3" java.lang.NoClassDefFoundError: kotlinx/coroutines/CoroutinesInternalError

my setup:

graphql {
  client {
    packageName = "my.package"
    endpoint = "http://my.url/graphql"
    val token = System.getProperty("graphql.token", graphqlToken)
    headers = mutableMapOf("X-Authentication" to token)
    customScalars = listOf(
        GraphQLScalar("LocalDate", "java.time.LocalDate", "my.package.LocalDateScalarConverter"),
        GraphQLScalar("Url", "java.net.URI", "my.package.UriScalarConverter")
    )
    queryFiles = fileTree("src/main/resources/graphql-queries").files.toMutableList()
  }
}

I believe this is the same as #1084. I am unsure why it happens - that internal error implies some uncaught exception from the HTTP call.

Yes that is true, so I close this discussion as it seems to be a reposted issue and it is more valuable to have all the information there :)
