Upgrade Kotlin to 2.x for Axon Framework 5

org.axonframework.migration.UpgradeKotlin

Bumps the org.jetbrains.kotlin:* dependency versions and the kotlin-maven-plugin to the configured Kotlin line (defaults to "2.x", the latest Kotlin 2.x). No-op for modules already at or above the target — the underlying upgrade recipes never downgrade. Rejects targets below Kotlin 2.0.

Options

Type	Name	Description	Example
String	targetVersion	Optional. Kotlin version (or Node-Semver selector) to upgrade to. Must resolve to Kotlin 2.0 or higher (Axon Framework 5 requires Kotlin 2.x+). Defaults to "2.x" so projects already on a higher 2.x release are left untouched. Updates the org.jetbrains.kotlin:* dependencies and the kotlin-maven-plugin version; does not apply Kotlin source-level rewrites.	2.x

This recipe is used as part of the following composite recipes:

• Upgrade to free Axon Framework 5

Usage

This recipe has no required configuration options. It can be activated by adding a dependency on `org.openrewrite.recipe:rewrite-third-party` in your build file or by running a shell command (in which case no build changes are needed):

Gradle

1. Add the following to your build.gradle file:
   build.gradle

   plugins {
       id("org.openrewrite.rewrite") version("latest.release")
   }
   
   rewrite {
       activeRecipe("org.axonframework.migration.UpgradeKotlin")
       setExportDatatables(true)
   }
   
   repositories {
       mavenCentral()
   }
   
   dependencies {
       rewrite("org.openrewrite.recipe:rewrite-third-party:0.40.1")
   }

2. Run gradle rewriteRun to run the recipe.

Gradle init script

1. Create a file named init.gradle in the root of your project.
   init.gradle

   initscript {
       repositories {
           maven { url "https://plugins.gradle.org/m2" }
       }
       dependencies { classpath("org.openrewrite:plugin:7.33.0") }
   }
   rootProject {
       plugins.apply(org.openrewrite.gradle.RewritePlugin)
       dependencies {
           rewrite("org.openrewrite.recipe:rewrite-third-party:0.40.1")
       }
       rewrite {
           activeRecipe("org.axonframework.migration.UpgradeKotlin")
       setExportDatatables(true)
       }
       afterEvaluate {
           if (repositories.isEmpty()) {
               repositories {
                   mavenCentral()
               }
           }
       }
   }

2. Run the recipe.
   shell

   gradle --init-script init.gradle rewriteRun

Gradle init script (Kotlin)

1. Create a file named init.gradle.kts in the root of your project.
   init.gradle.kts

   initscript {
       repositories {
           maven { url = uri("https://plugins.gradle.org/m2") }
       }
       dependencies { classpath("org.openrewrite:plugin:7.33.0") }
   }
   rootProject {
       plugins.apply(org.openrewrite.gradle.RewritePlugin::class.java)
       dependencies {
           add("rewrite", "org.openrewrite.recipe:rewrite-third-party:0.40.1")
       }
       extensions.configure<org.openrewrite.gradle.RewriteExtension> {
           activeRecipe("org.axonframework.migration.UpgradeKotlin")
       setExportDatatables(true)
       }
       afterEvaluate {
           if (repositories.isEmpty()) {
               repositories {
                   mavenCentral()
               }
           }
       }
   }

2. Run the recipe.
   shell

   gradle --init-script init.gradle.kts rewriteRun
