Crash with Kotlin version 1.3.70

Describe the bug

I was able to work well with Kotlin version 1.3.61 but now I am getting crash with Kotlin version 1.3.70

Caused by: java.lang.NoSuchMethodError: No direct method <init>(Ljava/lang/String;Lkotlinx/serialization/internal/GeneratedSerializer;I)V in class Lkotlinx/serialization/internal/SerialClassDescImpl; or its super classes (declaration of 'kotlinx.serialization.internal.SerialClassDescImpl' appears in /path)

To Reproduce Create these classes:

@Serializable
data class PolygonResponse(
    val maxSpeed: Int?,
    val polygons: List<Polygons?>
)

@Serializable
data class Polygons(
    val baseCapacity: Int?,
    val distanceToPolygon: Int?,
    val polygon: List<Polygon?>
)

@Serializable(with = PolygonSerializer::class)
data class Polygon(
    val coordinates: List<Double>
)
internal object PolygonSerializer : KSerializer<Polygon> {

    private val serializer = ArrayListSerializer(Double.serializer())

    override val descriptor: SerialDescriptor = StringDescriptor.withName("Polygon")

    override fun serialize(encoder: Encoder, obj: Polygon) {
        encoder.encode(serializer, obj.coordinates)
    }

    override fun deserialize(decoder: Decoder): Polygon {
        return Polygon(decoder.decode(serializer))
    }
}

Expected behavior Serialization should work properly.

Environment

• Kotlin version: [1.3.70]
• Library version: [0.14.0]
• Kotlin platforms: [JVM]
• Gradle version: [6.2.1]

[qwwdfsad]

kotlinx-serialization depends heavily on the compiler version (on the plugin bundled into compiler, actually), 0.14.0 is not compatible with 1.3.70. We will release 0.20.0 today and think out how to improve diagnostics here

[sandwwraith]

Version 0.20.0, which is compatible with 1.3.70, is now published on JCenter and will be available on Maven Central soon. Check out the release notes: https://github.com/Kotlin/kotlinx.serialization/blob/master/CHANGELOG.md#0200--2020-03-04
