Hi @yong-at-zettle!

Thanks for your interest.
Unfortunatelly Gradle is not yet supported. It would be possible but require more OpenRewrite Recipes modifying the Gralde files to apply the same modifications for Gradle as currently offered by BuildFile and imlemented in OpenRewriteMavenBuildFile for Maven. These must should go as contributions into OpenRewrite and then be used in a OpenRewriteGradleBuildFile also implementing BuildFile. (...and solving roadblocks on the way)
In case you'd be interested to look into this and maybe contribute something, please let us know.

Thanks for the reply, @fabapp2 !
Actually I intended to ask the support of migrating a project with Kotlin + Maven setup. But since OpenRewrite focuses on Java and spring-boot-migrator is based on OpenRewrite, hence it limits the support for Kotlin + Maven setup, right?
Cheers,
Yong

Sorry @yong-at-zettle!
It was from my mobile and I just realized your question was about Kotlin. 🤣 🙈

Unfortunatelly no, not yet.
As parsing and AST modifications rely solely on OpenRewrite this depends on the current Kotlin support in OpenRewrite. OpenRewrite has support for Kotlin but I am not sure about the coverage. Theoretically, it means the same as with Gradle support but JavaSource as base-interface and something like OpenRewriteKotlinSource as implementation. And most likely some roadblocks I am naively ignoring now.

Good to know. Thanks, @fabapp2 !
