How do you setup the Arrow dependencies for @optics annotation to actually work? No companion objects are generated for the data classes annotated with @optics.
If I'm not mistaken, this is an annotation processor, so it should be imported using kapt, however the documentation uses it as compile.
For arrow 0.10.0
apply plugin: 'kotlin-kapt'
def arrow_version = "0.10.1-SNAPSHOT"
dependencies {
implementation "io.arrow-kt:arrow-optics:$arrow_version"
implementation "io.arrow-kt:arrow-syntax:$arrow_version"
kapt "io.arrow-kt:arrow-meta:$arrow_version" // <-- this is the kapt plugin
}
then:
@optics data class Street(val number: Int, val name: String) {
companion object {} // <-- this is required
}
Everything is explained in the documentation, I don't know how I missed it
