Hello hello!
Im trying to build a super simple ktor based graphql server to run some android UI tests ( replacing kgraphql)
Im following this simpel example https://github.com/ExpediaGroup/graphql-kotlin/tree/master/examples/server/ktor-server/src/main/kotlin/com/expediagroup/graphql/examples/server/ktor

But I keep getting InvalidPackages exception ” The configured packages do not contain any valid classes..”
Ive triple checked the package name. Is there anyhting super obvious that Im missing? Cheers!

👋 can you share a link to a github repo?

[Marco Pierucci]

Heyo! Sorry am working directly on my company repo. Will see to create a small github repo to repo and share it

[Marco Pierucci]

Just running the app will throw the aftermentioned excepion when initializing the server

[Dariusz Kuc]

👋 so your issue is actually caused by attempting to run the graphql server from android

[Dariusz Kuc]

android does not use classfiles at runtime so when you attempt to start the server classgraph won't find any classes to load (see: https://github.com/classgraph/classgraph/discussions/567)

[Marco Pierucci]

Oh wow thats a shame 😞 but thanks for the response! At least it makes sense now, much appreciated!

[Dariusz Kuc]

Not super familiar with android so maybe there is a way

[Marco Pierucci]

Out of curiosity, is the scann needed for a simple use case like the one in my example? ( So that it could maybe be disabled via opt in )

[Marco Pierucci]

I guess its needed, okey nvm this was useful

[Dariusz Kuc]

I linked to the similar issue from graalvm -> we use it for polymorphism and fed2

[Dariusz Kuc]

Guess in the simplest cases it might not be needed but it is part of core functionality

[Marco Pierucci]

Yeah fair enough
