## setup

- install jdk 15 or later

- `build.sbt`

// https://github.com/scala/bug/issues/11908

// https://github.com/scala/bug/issues/12159

compileOrder := CompileOrder.JavaThenScala

```

- run `sbt -J--enable-preview`

## usage

```scala

import shapeless._

import shapeless.JavaRecordGeneric._

// summon shapeless.Generic instances

Generic[YourJavaRecordType]

Generic[YourJavaSealedType]

```

### LabelledGeneric

```scala

import shapeless._

import shapeless.JavaRecordGeneric._

import shapeless.JavaRecordGeneric.string._ // string label

// or import shapeless.JavaRecordGeneric.symbol._

LabelledGeneric[YourJavaRecordType]

LabelledGeneric[YourJavaSealedType]
