Enum annotations in Kotlin

I have an enum that serializes / deserializes Gson:

enum class PacketType { NONE; [SerializedName("request")] REQUEST; [SerializedName("response")] RESPONSE; [SerializedName("event")] EVENT; }

Unfortunately, I noticed that Gson ignores SerializedName annotations and uses uppercase names for enum values. I decided to find out why serialization does not work as intended, and found out that Kotlin leaves all the annotations for the enumeration values. How can I make these annotations in the generated bytecode?

Looks like a mistake. Please inform the questionnaire .

As a temporary workaround, you can write this class in Java

Now the problem is fixed, now your code works fine in Kotlin M9 (0.9.66). If you switch to this, it will work as you expect.

eg.

app build.gradle

 dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'org.jetbrains.kotlin:kotlin-stdlib:0.9.66' compile 'com.google.code.gson:gson:2.3' }

top level build.gradle

 buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:0.13.2' classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:0.9.+' } }

I confirmed this by doing an enumeration without any relationship between the enum names and the SerializedName names, and it worked as expected.
