# ADR-0003 - Avoid introducing Groovy types to public API

## Status

- ACCEPTED on 2024-01-12

## Context

Gradle's public API requires equal access from all JVM-based languages.
Kotlin, Groovy, Java, and other JVM-based languages should be able to use the Gradle API without relying on another language's standard library.

Historically, Gradle has shipped with some Groovy types in very prominent APIs.

th,\n  tbody + tbody {\n    border: 0;\n  }\n}\n\n// Zebra-striping\n//\n// Default zebra-stripe styles (alternating gray and transparent backgrounds)\n\n.table-striped {\n  tbody tr:nth-of-type(#{$table-striped-order}) {\n    background-color: $table-accent-bg;\n  }\n}\n\n\n// Hover effect\n//\n// Placed here since it has to come after the potential zebra striping\n\n.table-hover {\n  tbody tr {\n    @include hover() {\n      color: $table-hover-color;\n      background-color: $table-hover-bg;\n    }\n...
