Hello, I have a Java library and a Koltin library ...

# serialization

[Yao-Wen Mei]

Hello, I have a Java library and a Koltin library is depending on the Java library.

In the java library I have a class, Foo.java, Is that possible I can to mark it @Serializable (with = ContextualSerializer<Foo>.class) in side of Java, then use this Foo.java in my Kotlin library as it is Serializable, where inside of the Kotlin library, I define the SerializerModule (build a contextual serializer for Foo.java class and also a list of other classes), and then pass the SerializerModule to my custom ktxEncoder/ktxDecoder;

The key point for me to doing this is to avoid define a Kotlin serializer for Foo.java in my Java library (we are trying to have at least Kotlin file in the Java lib as possible).
Also trying to avoid the @Contextual annotation for my customers;

I'm inclined to say it's not possible to mark a Java class with @Serializable, just because the serializers are generated by a kotlin compiler plugin (by manipulating kotlin's IR?)

You definitely could implement a serializer yourself though

You could use Moshi and write a kotlinx serializer that delegates to Moshi.
