Usage​

This recipe has no required configuration parameters and comes from a rewrite core library. It can be activated directly without adding any dependencies.

OpenRewrite artifacts, including the Maven and Gradle plugins themselves, are distributed through the Code Genome Project repository (https://artifacts.codegenomeproject.org/maven), which requires authentication. Sign in to the Code Genome Project to create a download token; your build authenticates with the email or username you signed in with, plus that token as the password. See the quickstart guide for details.

  1. Put your Code Genome Project credentials in ~/.gradle/gradle.properties, so that they are not committed alongside your build:
    ~/.gradle/gradle.properties
    codeGenomeUsername=you@example.com
    codeGenomeToken=your-download-token
  2. Add the Code Genome Project repository to your settings.gradle file, so that the plugin itself can be resolved:
    settings.gradle
    pluginManagement {
        repositories {
            maven {
                url = "https://artifacts.codegenomeproject.org/maven"
                credentials {
                    username = providers.gradleProperty("codeGenomeUsername").get()
                    password = providers.gradleProperty("codeGenomeToken").get()
                }
            }
            // Keep the portal for any other plugins your build applies
            gradlePluginPortal()
        }
    }
  3. Add the following to your build.gradle file:
    build.gradle
    plugins {
        id("org.openrewrite.rewrite") version("latest.release")
    }

    rewrite {
        activeRecipe("org.openrewrite.kotlin.FindKotlinSources")
        setExportDatatables(true)
    }

    repositories {
        mavenCentral()
        maven {
            url = "https://artifacts.codegenomeproject.org/maven"
            credentials {
                username = providers.gradleProperty("codeGenomeUsername").get()
                password = providers.gradleProperty("codeGenomeToken").get()
            }
        }
    }
