Quick start guide using Maven

The quick start guide only includes Gradle tutorial, is possible use it with Maven?

Hi. You can setup any of the following artifacts:
https://kotlin.github.io/dataframe/gettingstartedgradleadvanced.html#custom-configuration

<dependency>
    <groupId>org.jetbrains.kotlinx</groupId>
    <artifactId>dataframe</artifactId>
    <version>0.13.1</version>
    <scope>runtime</scope>
</dependency>

However Gradle plugin for generating schema from the data and KSP plugins are Gradle only. If you want to use DataSchema API in Maven project, code can be generated like this

import org.jetbrains.kotlinx.dataframe.*
import org.jetbrains.kotlinx.dataframe.api.*
import org.jetbrains.kotlinx.dataframe.io.*
import org.jetbrains.kotlinx.dataframe.codeGen.generateCode

fun main() {
    val df = dataFrameOf("a")(1) // DataFrame.read(...) or something
    println(df.generateCode(markerName = "YourData"))
}

The output can be copy-pasted in the project sources:

@DataSchema
interface YourData {
    val a: kotlin.Int
}

val org.jetbrains.kotlinx.dataframe.ColumnsContainer<YourData>.a: org.jetbrains.kotlinx.dataframe.DataColumn<kotlin.Int> @JvmName("YourData_a") get() = this["a"] as org.jetbrains.kotlinx.dataframe.DataColumn<kotlin.Int>
val org.jetbrains.kotlinx.dataframe.DataRow<YourData>.a: kotlin.Int @JvmName("YourData_a") get() = this["a"] as kotlin.Int

Usage:

fun main() {
    val df = dataFrameOf("a")(1).cast<YourData>(verify = true)
    df.a
}

Hope there is an official maven plugin that can do the same generation as Gradle plugin.

Indeed, we will consider it #722
