+# Gradle Parser Implementation Plan
+
+## Overview
+This document describes the implementation plan and execution steps for adding Gradle manifest parsing support to the `manifest-parser` repository.
+
+The parser was extended to support static Gradle dependency declarations in both Groovy and Kotlin DSL, including common production patterns such as multi-line dependencies and conditional `if` blocks.
+
+---
+
+## Implementation Plan
+
+### 1. Analyze existing code flow
+- Inspect `cmd/main.go` to understand entrypoint behavior.
+- Review `pkg/parser/parser.go` and `pkg/parser/parser_factory.go` to understand the parser interface and factory logic.
+- Review `pkg/parser/manifest-file-selector.go` to see how manifest types are detected.
+- Review existing language parser implementations for style and output format.
+
+### 2. Add Gradle manifest detection
+- Extend `pkg/parser/manifest-file-selector.go` to recognize `build.gradle` and `build.gradle.kts` files.
+- Add a new `Manifest` type for Gradle.
+
+### 3. Add factory support for Gradle
+- Update `pkg/parser/parser_factory.go` to import the new Gradle parser.
+- Return the Gradle parser instance when the selected manifest is Gradle.
+
+### 4. Implement Gradle parser
+- Create `internal/parsers/gradle/gradle_parser.go`.
+- Implement the `Parser` interface for Gradle.
+- Parse dependencies into `models.Package` entries.
+
+### 5. Add variable resolution
+- Read `gradle.properties` values.
+- Parse Groovy `ext {}` blocks and `ext.key` assignments.
+- Parse Kotlin DSL `val` and `const val` declarations.
+- Resolve `${var}` and `$var` references in dependency strings.
+
+### 6. Add support for multi-line dependency declarations
+- Detect dependency statements spanning multiple lines.
+- Join logical dependency lines before parsing.
+- Support both string notation and map notation across line breaks.
+
+### 7. Add conditional dependency support
+- Parse dependencies inside conditional blocks such as `if (...) { ... }`.
+- Treat static declarations inside conditionals as valid parse targets.
+
+### 8. Add Kotlin DSL support
+- Support Kotlin string syntax: `implementation("group:name:version")`.
+- Support Kotlin map syntax: `implementation(group = "group", name = "name", version = "version")`.
+- Support Kotlin-style dependency declarations in `build.gradle.kts`.
+
+### 9. Write regression tests
+- Create or update `internal/parsers/gradle/gradle_parser_test.go`.
+- Add tests for:
+  - basic Groovy dependencies
+  - multi-line dependencies
+  - conditional `if` block dependencies
+  - Kotlin DSL dependency syntax
+
+### 10. Validate
+- Run `go test ./internal/parsers/gradle`.
+- Confirm Gradle parser tests pass.
+- Optionally run `go test ./...` to verify broader repository compatibility, noting existing unrelated test failures.
+

+## Files created or modified
+
+- `pkg/parser/manifest-file-selector.go`
+- `pkg/parser/parser_factory.go`
+- `internal/parsers/gradle/gradle_parser.go`
+- `internal/parsers/gradle/gradle_parser_test.go`
+- `test/resources/build.gradle` (sample Gradle fixture)
+
+---
+
+## Supported Gradle parser features
+
+- Detection of `build.gradle` and `build.gradle.kts` files
+- Parsing of common dependency configurations:
+  - `implementation`, `api`, `compile`, `compileOnly`, `runtime`, `runtimeOnly`
+  - `testImplementation`, `testCompile`, `testRuntimeOnly`
+  - `androidTestImplementation`, `annotationProcessor`, `classpath`, `kapt`
+- String-style dependency declarations
+- Map-style dependency declarations
+- Multi-line dependency statements
+- Dependencies inside `if (...) { ... }` blocks
+- Variable resolution from:
+  - `gradle.properties`
+  - Groovy `ext` property blocks
+  - Groovy `ext.key = value` syntax
+  - Kotlin DSL `val` / `const val`
+- Kotlin DSL dependency syntax
+- Version cleanup for simple ranges and classifiers
+
+---
+
+## Known limitations
+
+- Dynamic dependencies generated by build logic, loops, or plugin APIs are not resolved.
+- Complex Kotlin DSL constructs beyond common forms may not be fully parsed.
+- Conditional branch logic is not evaluated; all static declarations are treated as present.
+- Deep nested DSL or custom Gradle extension syntax may be missed.
+- Computed or function-based version expressions are not evaluated.
+- Multi-project and included-build dependency resolution is not supported.
+
+---
+
+## Notes
+
+The Gradle parser is now suitable for many production scanning scenarios in AST-CLI where static dependency declarations are present. For full Gradle model accuracy, additional Gradle-aware parsing or integration with Gradle tooling would be required.
