# serialization

Maybe a typo somewhere? Any differences from this pom? https://github.com/Kotlin/kotlinx.serialization/blob/master/example-jvm/pom.xml

[ValV]

Few differences:
1. I have no maven-compiler-plugin and maven-exec-plugin
2. I have 2 additional dependencies: tornadofx and kotlin-test
3. For kotlin-maven-plugin jvmTarget is being set inside <plugin><executions><execution><configuration>
4. <packaging> into pom, not jar as in the example

[ValV]

With version 0.6.2 that worked just fine

[ValV]

It is painful to update Maven repository, 'cause it takes too long while downloading 500+ MiB of archives

[ValV]

Each time

[sandwwraith]

Then it should work fine, a single difference from 0.6.2 plugin was group change from kotlinX to kotlin. There's this artifact: https://search.maven.org/artifact/org.jetbrains.kotlin/kotlinx-maven-serialization-plugin/1.3.0/jar

[ValV]

Yep, I've noticed that change. So the problem is somewhere in Maven repository

[ValV]

Hmm... find ~/.m2 -type f -name '*seralization*0.9.0*jar' returned org/jetbrains/kotlinx/kotlinx-serialization-runtime/0.9.0/kotlinx-serialization-runtime.jar + the same for *runtime-common*

[ValV]

And that's all -- just 2 jars

[ValV]

Where does kotlinx-maven-serialization-plugin reside? Maybe it's not in maven-central?

[sandwwraith]

It is, as the attached link shows

[ValV]

@sandwwraith this problem is fixed by setting kotlin.version to 1.3.10, not 1.3.0. For some reason Maven does not find org.jetbrains.kotlin:kotlinx-maven-serialization-plugin:1.3.0 in its Central

[ValV]

But another problem occurs: [Internal Error] Exception while analyzing expression -- just where the first @Serializable class must return its serializer().list

[sandwwraith]

Can you post a bigger stacktrace, please?

[sandwwraith]

I gave you link on 1.3.0 on Maven Central, is it wrong?

[ValV]

I'd better say that 1.3.0 not wrong, but it did not work for me (with IDEA). Here is the stacktrace for the new exception

Here is the source https://github.com/ValV/Directorium/blob/9f911689bdfc81b617cc47414a8a7d2c3135300a/directorii-nucleus/src/main/kotlin/com/github/valv/directorium/control/Data.kt#L41

[ValV]

I have disabled Kotlin-serialization IDEA plugin (it was version 0.6.2), even with that plugin disabled the error persists

[ValV]

Well, I tried to compile the project without IDE(A) at all, and Maven gave more comprehensive errors

msg.txt

[ValV]

Looks like I've missed many changes from 0.6.2 to 0.9.0, so no more contexts?

[ValV]

Yet still I don't understand what's wrong in 41:32. Shall I use some interface instead of @Serializable?

[sandwwraith]

First error message looks like incompatible versions, so yes, you should disable the old plugin and delegate build to Gradle.

[sandwwraith]

Context were reworked, see updated docs: https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/custom_serializers.md#registering-and-context

[ValV]

So I need serialization plugin for IDEA, now? Just like that disabled for 0.6.2 but for the new 0.9.0 (I haven't find it yet), 'cause with Maven the project builds, but with IDEA it feeds me with the Internal Error

[sandwwraith]

IDEA plugin is now bundled with the rest Kotlin distribution
