Hello, I'm trying to use kotlinx.serialization with a KotlinJs project without gradle or maven (don't ask :D). I've added the serialization runtime library manually and I can compile the examples. But, IntelliJ shows errors in the code as "unresolved reference kotlinx". I've tried to install the plugin as described in "Working in IntelliJ IDEA" section, but I get this warning "Plugin 'Kotlin-serialization' was already installed". I'm using the latest IntelliJ 2017.3.1. I supose I need to add the serialization plugin to the Kotlin compiler plugin. Can this be achieved?

If it’s installed in IDEA, it should work out-of-box for JPS(idea build system) compilation. Do you see it in “plugins” list in section?

Yes, I can see Kotlin-serialization 0.3 in the list.

Then ‘unresolve reference’ mean that’s something wrong with runtime library. If I did understand you correctly, examples compile and run well, but code in IDEA is red?

I did not run it, but I read the generated .js file, and looks ok for me 😄

Have you added kotlin-serialization-runtime-js.jar as library in project settings?

yes I did

with plugin and runtime library it should work, then. maybe some issue with idea indexes

I can ask a coworker to open the project on his computer, to see if he has the same problem. It's a simple example

not sure it’s plugin-related, it’s not responsible for resolving

kotlinx.*

package, only synthetic declarations for your own classes

aha

classes from kotlinx.serialization are usual classes, as in any other library

My coworker had opened the project with his computer and he has the same issue.. compiles fine, but IDEA complains 😄

🤔

Ok, this might help I get this error on running so the compiler plugin is not working for me: "SerializationException: Can't locate companion serializer for class class JoinToGameRequest"

okay. 😞 can you share your sample so I can try to reproduce problem?

Slack says "This file can’t be found" for your link

Thx!

That's it! Thanks!

You’re welcome 🙂 Maybe behaviour of “Add as library” worth reporting to youtrack, because it is slightly counter-intuitive

Seems plugin wasn’t detected in your project. However, it works in my another JS/JPS project, I’ll take a look at differences

I've updated to 1.2.20-eap but I gives another error when deserializing. "TypeError: this is undefined" I'm guessing the line "this.a = a;" should be "$this.a = a;"

could you provide some sample? I think this is related to class inheritance, right?

Is the same sample 😄

🤔 🤔 🤔

oh

in 1.2.10, it generates

$this.a = a

with 1.2.10-release-IJ2017.3-1 I do not get serializing code generated. It seems that I need to wait for the next release XD

Unfortunately, yes. I meant that gradle build works with 1.2.10. But I see you really want not to mess with gradle 🙂

I'm working with some projects at once, and I use gradle on most of them, but with this project with KotlinJS only is not really useful, at the moment, because we had no dependencies, until kotlinx-serialization 😄 Maybe in a near future, when we want to automatize builds, but now using gradle for this project seems like an unneccessary overhead.
