org.openrewrite.Recipe

org.axonframework.migration.UpgradeKotlin

All Implemented Interfaces:

Cloneable

public class UpgradeKotlin
extends org.openrewrite.Recipe

Bumps Kotlin to a configurable 2.x line, with validation that the target satisfies the Axon Framework 5 minimum (Kotlin 2.0).

Wraps two upstream recipes to cover the two places a Kotlin version is pinned in a typical Maven build:

• UpgradeDependencyVersion for org.jetbrains.kotlin:* — bumps kotlin-stdlib, kotlin-reflect, kotlin-stdlib-jdk8, and any other Kotlin runtime artifacts the project declares (Maven and Gradle); and
• UpgradePluginVersion for org.jetbrains.kotlin:kotlin-maven-plugin — bumps the Kotlin compiler plugin so Maven builds compile against the new language line.

The default target is "2.x" (Node-Semver "latest 2.x"), chosen so projects already on a higher Kotlin 2.x release are left untouched — UpgradeDependencyVersion only upgrades, never downgrades.

The targetVersion option is overridable per invocation; values whose major version is below 2 are rejected so misconfigurations fail loudly rather than silently pinning the build to a Kotlin 1.x line that Axon Framework 5 does not support.

Since:

5.1.1

Field Details

DEFAULT_TARGET_VERSION

public static final String DEFAULT_TARGET_VERSION

Default Node-Semver selector used when targetVersion is unset. "2.x" resolves to the latest published Kotlin 2.x release, so projects already on a higher 2.x line are left untouched (the underlying upgrade recipes never downgrade).

• Constant Field Values

MINIMUM_MAJOR_VERSION

public static final int MINIMUM_MAJOR_VERSION

Minimum supported major version. Axon Framework 5 requires Kotlin 2.x or higher; targets whose major component is below this are rejected at configuration time.
