12/19/2017, 11:03 AMHello, 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?

12/19/2017, 2:01 PMIf 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?

12/19/2017, 3:31 PMYes, I can see Kotlin-serialization 0.3 in the list.

12/19/2017, 5:03 PMThen ‘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?

12/19/2017, 5:06 PMI did not run it, but I read the generated .js file, and looks ok for me 😄
hiperbou
12/19/2017, 5:09 PMthe kotlin-serialization-runtime-js.js and .meta.js are copied also on the out folder.. everything looks ok, except IDEA complaining about the code

12/19/2017, 5:10 PMHave you added kotlin-serialization-runtime-js.jar as library in project settings?
h
hiperbou
12/19/2017, 5:10 PMyes I did
s
sandwwraith
12/19/2017, 5:11 PMwith plugin and runtime library it should work, then. maybe some issue with idea indexes
h
hiperbou
12/19/2017, 5:12 PMI can ask a coworker to open the project on his computer, to see if he has the same problem. It's a simple example
hiperbou
12/19/2017, 5:12 PMI had installed manually the old 0.1 plugin, maybe could be something like that..
s
sandwwraith
12/19/2017, 5:13 PMnot sure it’s plugin-related, it’s not responsible for resolving
kotlinx.*h

12/19/2017, 5:15 PMaha

sandwwraith
12/19/2017, 5:16 PMclasses from kotlinx.serialization are usual classes, as in any other library

hiperbou
12/19/2017, 5:44 PMMy coworker had opened the project with his computer and he has the same issue.. compiles fine, but IDEA complains 😄

12/20/2017, 11:51 AMOk, 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"

sandwwraith
12/20/2017, 11:56 AMokay. 😞 can you share your sample so I can try to reproduce problem?

12/20/2017, 12:14 PMThx!
sandwwraith
12/21/2017, 12:16 PMSorry for late response, I finally found how to help you: In Project Settings -> Libraries, kotlinx-serialization-runtime-js.jar was added as Java library. You have to add it as Kotlin/JS library (last menu item under ➕ ). Then it can be indexed by IDEA
h
hiperbou
12/21/2017, 1:31 PMThat's it! Thanks!
hiperbou
12/21/2017, 1:32 PMI've added the library by right clicking and selecting the "Add as library" and by default it adds as a Java library...
hiperbou
12/21/2017, 1:32 PMdidn't thought of it
hiperbou
12/21/2017, 1:33 PMThanks again! 👍

sandwwraith
12/21/2017, 1:35 PMYou’re welcome 🙂 Maybe behaviour of “Add as library” worth reporting to youtrack, because it is slightly counter-intuitive
h
hiperbou
12/21/2017, 1:50 PM👍 1
hiperbou
12/21/2017, 2:09 PMmmm.. I still get the error "SerializationException: Can't locate companion serializer for class class XX" I've invalidated cache, restarted and rebuilt the project 😨

sandwwraith
12/21/2017, 2:24 PMSeems plugin wasn’t detected in your project. However, it works in my another JS/JPS project, I’ll take a look at differences
sandwwraith
12/21/2017, 2:53 PMAh, totally forgot about it. Kotlin/JS compilation in JPS with plugin will be available only in 1.2.20, because corresponding entry points for plugin were merged very recently
sandwwraith
12/21/2017, 2:53 PMYou can try 1.2.20-eap
h
hiperbou
12/21/2017, 3:47 PMI'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;"
s
sandwwraith
12/21/2017, 4:28 PMcould you provide some sample? I think this is related to class inheritance, right?
h
hiperbou
12/21/2017, 4:40 PMIs the same sample 😄

12/21/2017, 4:42 PM🤔 🤔 🤔

12/21/2017, 4:51 PMindeed
sandwwraith
12/21/2017, 4:51 PMseems compatibility between my branch and upstream compiler was broken
h
hiperbou
12/21/2017, 5:05 PMoh
s
sandwwraith
12/21/2017, 5:07 PMin 1.2.10, it generates
$this.a = ah
hiperbou
12/22/2017, 10:20 AMwith 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
s
sandwwraith
12/22/2017, 10:22 AMUnfortunately, yes. I meant that gradle build works with 1.2.10. But I see you really want not to mess with gradle 🙂
h
hiperbou
12/22/2017, 11:02 AMI'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.
