Migration from Gradle/KSP Plugin

Gradle and KSP plugins were useful tools in earlier versions of Kotlin DataFrame.
However, they are now deprecated. Their latest release is 1.0.0-Beta4 and will not have future releases. This page provides migration guidance.

Our plans for the next iteration of schema generation from source feature can be found in Issue #1844.

Gradle Plugin

Latest available release of the deprecated plugin:

plugins {
    id("org.jetbrains.kotlinx.dataframe") version "1.0.0-Beta4"
}

Generation of data schemas from data sources
(files, databases, or external URLs).
- You could copy already generated schemas from build/generate into your project sources.
- To generate a DataSchema for a DataFrame now, use the generate..() methods.
Generation of extension properties from data schemas
This is now handled by the compiler plugin, which:
- Generates extension properties for declared data schemas.
- Automatically updates the schema and regenerates properties after structural DataFrame operations.

KSP Plugin

Latest available release of the deprecated processor:

dependencies {
    ksp("org.jetbrains.kotlinx.dataframe:symbol-processor-all:1.0.0-Beta4")
}

Generation of data schemas from data sources
(files, databases, or external URLs).
- You could copy already generated schemas from build/generate/ksp into your project sources.
- To generate a DataSchema for a DataFrame now, use the
  generate..() methods instead.
