The error comes from the fact that the rewrite Java parser cannot find from the classpath "quarkus-core"

Fix

To fix this issue it is needed to generate using the following goal the typetables packaging the needed classes, jars as documented here: https://docs.openrewrite.org/authoring-recipes/multiple-versions#typetable-generation-for-maven-projects

mvn org.openrewrite.maven:rewrite-maven-plugin:typetable -Drewrite.recipeArtifactCoordinates="io.quarkus:quarkus-core:3.29.0"

TODO

Add to the pom.xml of the openrewrite-recipes module the following plugin and dependencies needed

<profiles>
    <!--
        When you want to generate a TypeTable for use in JavaParser for JavaTemplate, run the following command:
        ./mvnw generate-resources -Ptypetable
