An instance is created at the start of a build execution and discarded at the end of the execution.

### Build state

The "build state" holds the state for a build within the build definition for a single build execution, and is contained by the build tree state.

The build state is managed by the `BuildState` class.
An instance is created for each build in the build definition, once per build execution and is discarded at the end of the execution.

# Gradle architecture documentation

This directory contains documentation that describes Gradle's architecture and how the various pieces fit together and work.

## Architecture decision records (ADRs)

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

See [Architecture decisions records](standards) for the list of ADRs.

  - pr_created
  - commit
  - comment_added

* Keep commits discrete. Avoid including multiple unrelated changes in a single commit.
* Keep commits self-contained. Avoid spreading a single change across multiple commits. A single commit should make sense in isolation.

### Testing changes

After making changes, you can test your code in 2 ways:

1. Run tests.

# Gradle platform architecture

Gradle is arranged into coarse-grained components called "architecture modules" and "platforms".
See [ADR4](standards/0004-use-a-platform-architecture.md) for a definition of these terms.

The diagram below shows the current set of architecture modules and platforms:

        "org/gradle/model/**",
        "org/gradle/testkit/**",
        "org/gradle/testing/**",
        "org/gradle/vcs/**",
        "org/gradle/work/**",
        "org/gradle/workers/**",
        "org/gradle/util/**", // contains Path that clashes with `org.gradle.api.model.Path` imported above. This line should not appear before "org/gradle/api/**"
    )

    val excludes = listOf("**/internal/**")

dependencies {
    baseline("gradle:gradle:${compatibilityBaselineVersion}@zip")

    // This transform takes the Gradle zip distribution,
    // and unzips the Gradle jar files that it contains in a directory
    registerTransform(ExplodeZipAndFindJars) {
        from.attribute(ARTIFACT_TYPE, 'zip')
        to.attribute(ARTIFACT_TYPE, 'gradle-libs-dir')
    }
    registerTransform(FindGradleClasspath) {
