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

## Date

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.

import java.io.File


class TestFilesCleanupRootPlugin : Plugin<Project> {
    override fun apply(project: Project) {
        require(project.rootProject == project) { "This plugin should be applied to root project!" }
        val globalExtension = project.extensions.create<TestFilesCleanupBuildServiceRootExtension>("testFilesCleanupRoot")
        project.gradle.taskGraph.whenReady {

        byte[] dst2 = new byte[256];
        int bytesWritten2 = netShareEnum.writeParametersWireFormat(dst2, 100);

        // Same number of bytes should be written
        assertEquals(bytesWritten1, bytesWritten2);

        // Data should be the same, just at different offsets
        for (int i = 0; i < bytesWritten1; i++) {
            assertEquals(dst1[i], dst2[100 + i]);
        }
    }

        SID s2 = sid("S-1-5-21-10-11-12-1002");
        SID s3 = sid("S-1-5-21-10-11-12-1003");
        jcifs.SID[] arr = new jcifs.SID[] { s1, s2, s3 };

        // First call should resolve two (offset=0,length=2)
        doAnswer(inv -> {
            // Simulate resolve call by setting names/types and thus enabling cache population
