Java serialization fix for Kotlin object

Solves the problem of Kotlin object being having different instance after deserialization using built-in Java serialization. The issue is described quite well here.

The plugin adds readResolve method for every object which either:

• implements java.io.Serializable;
• extends a class implementing java.io.Serializable.

Getting it:

// build.gradle

// plugins dsl
plugins {
  id "me.shika.kotlin-object-java-serialization" version "1.1.0"
}

// or else
buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "me.shika:kotlin-object-java-serialization:1.1.0"
  }
}

apply plugin: 'me.shika.kotlin-object-java-serialization'
