Groovy in Other Platforms

Scripting and automation: system admin scripts, CSV/Excel processing (Apache POI), cloud SDK automation (AWS/GCP/Azure Java SDKs), and file conversions.

Data pipelines and bioinformatics: Nextflow (a Groovy-based workflow DSL used widely in genomics).

Apache NiFi (ExecuteGroovyScript processor), Apache Camel (Groovy expressions/routes), Elasticsearch/OpenSearch (Painless is Groovy-inspired), Liquibase (Groovy changelogs), Atlassian ScriptRunner (Jira/Confluence automation), SmartThings (historical), Liferay, SoapUI.

Android: historically via the Groovy Android plugin. Now uncommon (Kotlin dominates), though the Gradle Groovy DSL is still used for Android builds.

Desktop GUIs: groovy-swing (SwingBuilder), GroovyFX (JavaFX builder), Griffon (discontinued).

GraalVM native image: possible with @CompileStatic code and reflection configuration (Micronaut helps).

Jupyter: BeakerX (historical), the Ganymede kernel, IJava with Groovy.
