Kotlin source files under src/main/java should be detected

[reisners]

What version of OpenRewrite are you using?

I am using

• OpenRewrite v8.43.3
• Maven/Gradle plugin v6.0.3

How are you running OpenRewrite?

I am using the Maven plugin, and my project is a single module project.

<plugin>
  <groupId>org.openrewrite.maven</groupId>
  <artifactId>rewrite-maven-plugin</artifactId>
  <version>1.2.3</version>
  <configuration>
    ... 
  </configuration>
</plugin>

What is the smallest, simplest way to reproduce the problem?

Given Kotlin source filesrc/main/java/sample/MyClass.kt with content below,

 package sample
  class MyClass {
     }

and the kotlin-maven-plugin configured as follows,

                        <configuration>
                            <sourceDirs>
                                <sourceDir>${project.basedir}/src/main/java</sourceDir>
                            </sourceDirs>
                        </configuration>

invoking the Autoformat recipe using this command line

mvn -U org.openrewrite.maven:rewrite-maven-plugin:6.0.3:run -Drewrite.recipeArtifactCoordinates=org.openrewrite.recipe:rewrite-all:1.3.4 -Drewrite.activeRecipes=org.openrewrite.kotlin.format.AutoFormat

What did you expect to see?

The Kotlint source file src/main/java/sample/MyClass.kt should have been detected and reformatted into

package sample
class MyClass {
}

What did you see instead?

The Kotlin source file at src/main/java/sample/MyClass.kt was not detected and therefore not reformatted.

What is the full stack trace of any errors you encountered?

There was no error.

Are you interested in contributing a fix to OpenRewrite?

Yes, I am preparing a PR with a fix.

@reisners could you retest with your local build plugin and briefly report the result?
mvn install and updating the build using it should do the trick.
