Does graphlq-kotlin work with spring 2.7.0? I’m using 5.4.1 https://github.com/rowi1de/graphql-reactive/runs/6516519218?check_suite_focus=true#step:5:66

Caused by: java.lang.ClassCastException at SchemaPrinter.java:762

@Saurav Tapader just opened up a PR to bump the dependencies (including spring boot 2.7)

needs some approval

that being said -> schema printer is from

graphql-java

so it kind of looks like you got classpath problem with

graphql-java

and not spring

I only include implementation("com.expediagroup:graphql-kotlin-spring-server:5.4.1")

hmm unsure then, it certainly does look like some classpath issue ->

graphql-kotlin 5.4.1

depends on

graphql-java 17.2

but it only increments count in the schema printer (https://github.com/graphql-java/graphql-java/blob/v17.2/src/main/java/graphql/schema/idl/SchemaPrinter.java#L762) In the latest

graphql-java

(18.1) it attempts to get list of predicates -> https://github.com/graphql-java/graphql-java/blob/v18.1/src/main/java/graphql/schema/idl/SchemaPrinter.java#L762 which used to be

Predicate<GraphQLDirective>

(in old version) and are now just

Predicate<String>

Thanks for the hint, worth a try. It's just a demo project with automated dependabot PRs, which just bumped spring from 2.6.7 to 2.7.0. Spring now has an own grapql starter based on graphql-java .. maybe this is messing up something?

indeed good callout

I don't include that starter but could think something in spring boot itself could do some autoconfiguration because some graphql-java is on the classpath… just guessing, would need to check later

try debugging your classpath to see where it comes from

id("io.spring.dependency-management") version "1.0.11.RELEASE"

here it comes from

I dont think you need the spring dep management plugin (wasnt this an old deprecated way? I think you can import boms using

platform

dep)

https://start.spring.io/#!type=gradle-project&amp;language=kotlin&amp;platformVersion=2.7.0&amp;packaging=jar&amp;jvmVersion=17&amp;groupId=com.example&amp;artifactId=demo&amp;name=demo&amp;description=Demo%20project%20for%20Spring%20Boot&amp;packageName=com.example.demo<https://start.spring.io/#!type=gradle-project&language=kotlin&platformVersion=2.7.0&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo|

I think it's up to date

Yeah they still publish it but I think using bom natively (through platform) is generally preferred option

That would make it easier, good to know 👍🏻
