Question 1

How do I convert my existing pom.xml to YAML using Polyglot Maven?

Accepted Answer

Use the translate plugin with the command: mvn io.takari.polyglot:polyglot-translate-plugin:translate -Dinput=pom.xml -Doutput=pom.yaml. This converts the XML POM to YAML format, as documented in the README's conversion section, and works for other formats like Ruby or Kotlin.

Question 2

Polyglot Maven vs Gradle: which is better for Kotlin projects?

Accepted Answer

Polyglot Maven allows writing Maven POMs in Kotlin, keeping Maven compatibility, while Gradle has native Kotlin DSL support. Choose Polyglot Maven if you're tied to Maven's ecosystem; otherwise, Gradle might offer better out-of-the-box Kotlin integration and tooling.

Question 3

Does Polyglot Maven work well with IntelliJ IDEA?

Accepted Answer

It has basic syntax highlighting in IntelliJ IDEA, but full Maven-specific integration like pom.xml editing features is limited. The README notes that tooling support is incomplete, so expect gaps in code assistance or validation.

Question 4

Can I use Ruby for one module and Scala for another in a multi-module project?

Accepted Answer

No, mixing different dialects within a reactor is not supported. The README states this as a known limitation in the interoperability section, so you must use a single dialect across all modules in a project.

Question 5

What happens if I try to use the Maven Release Plugin with Polyglot Maven?

Accepted Answer

It will likely fail because the Release Plugin relies on parsing and modifying XML POMs directly. The README lists the Maven Release Plugin as incompatible and suggests that workarounds or replacement workflows are needed for release processes.

Question 6

Is Polyglot Maven stable enough for production use?

Accepted Answer

Yes, it's described as stable in the README with real-world usage examples like JRuby and SnakeYAML, but be aware of limitations like plugin incompatibility. However, some projects have switched away to tools like Mill or sbt over time.
