The Gradle team uses ADRs to record architectural decisions that the team has made.

See [Architecture decisions records](standards) for the list of ADRs.
Be aware these are very technical descriptions of the decisions, and you might find the documentation below more useful as an introduction to the internals of Gradle.

## Platform architecture

Gradle is arranged into several coarse-grained components called "platforms".

    val runtimeClasspath by configurations
    val externalComponents by lazy {
        runtimeClasspath.incoming.resolutionResult.rootComponent.map { rootComponent ->
            val rootVariant = rootComponent.variants.find { it.displayName == runtimeClasspath.name }
            rootVariant?.let { computeExternalDependenciesNotAccessibleFromProjectDependencies(rootComponent, it) } ?: emptySet()
        }.get()
    }

        assertEquals("clean myTask", getGradleStep("GRADLE_RUNNER").tasks)
    }

    private
    fun getGradleStep(stepName: String) = steps.items.find { it.name == stepName }!! as GradleBuildStep

    private
    fun expectedRunnerParam(daemon: String = "--daemon", extraParameters: String = "", os: Os = Os.LINUX): String {
        val linuxPaths =

    });

    console.log("computeStatistics: ");
    console.log(summaries)
    return summaries;
}

function metadataFor(fileMetadatas, file) {
    return fileMetadatas.find(fileMetadata => fileMetadata.file == file);
}

  - If there are any errors, read the error and fix your code.
  - IMPORTANT NOTE: if the first import fails, you have to select and apply `Synchronization disabled`, then repeat the step above.
    Otherwise, TeamCity complains "Can't find the previous revision, please commit current settings first".
  - If anything bad happens, feel free to delete the project you created and retry (you may need to apply `Synchronization disabled` before deleting it).

If you're looking to contribute to Gradle or provide a patch/pull request, you can find more info [here](https://github.com/gradle/gradle/blob/master/CONTRIBUTING.md).

        when:
        repository.put('class', value)

        then:
        repository.find('class') == value
        repository.get('class') == value
    }

    def findReturnsNullForUnknownClass() {
        expect:
        repository.find('unknown') == null
    }

    def getFailsForUnknownClass() {
        given:

        Map<AccessorKey, ReplacedAccessor> oldAccessorsOfUpgradedProperties = (Map<AccessorKey, ReplacedAccessor>) context.getUserData().get(OLD_ACCESSORS_OF_UPGRADED_PROPERTIES);

        // Find accessors that were not removed but should be
        Map<AccessorKey, ReplacedAccessor> keptAccessors = new HashMap<>(oldAccessorsOfUpgradedProperties);
        keptAccessors.entrySet().removeIf(e -> {

        psOutput.forEach(line -> {
            Matcher commandLineArgsMatcher = commandLineArgsPattern.matcher(line);
            Matcher pidMatcher = pidPattern.matcher(line);
            if (commandLineArgsMatcher.find() && pidMatcher.find()) {
                String pid = pidMatcher.group(1);
                if (!MY_PID.equals(pid)) {
                    action.accept(pid, line);
                }
            }
        });
    }

## Structure

Each platform and module has its own source directory under [platforms/](../platforms).
In these source directories, you will find the Gradle projects that make up the platform or module.

The platforms and modules are defined using a DSL in [settings.gradle.kts](../settings.gradle.kts)
