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. diff --git a/internal/parsers/gradle/gradle_parser.go

Callers should not expect any log output from the library. +- The **CLI** (`cmd/main.go`) uses `log.Fatalf` on parse/marshal errors and exits non-zero. Normal output is JSON printed to stdout. + +## Coding Standards + +- `gofmt` and `go vet` clean โ€” CI will fail otherwise. +- Exported identifiers live in `pkg/`; internal logic lives in `internal/`. Do not add exported symbols to `internal/`. +- Parser packages follow the naming layout: `internal/parsers//_parser.go` + `_parser_test.go`. +- No global state in parsers โ€” each concrete parser type is a stateless zero-value struct. + +## Debugging Steps + +1. **Run one parser against a fixture:** + ```bash + go run ./cmd test/resources/pom.xml + go run ./cmd test/resources/build.gradle + ``` + +2. **Verbose test output to see which test case fails:** + ```bash + go test -v ./internal/parsers/maven/... + ``` -## Tests & fixtures +3. **Location off-by-one:** check the 0-based invariant โ€” the parser should use `lineNum - 1` or a 0-based counter. Grep for `Line:` assignments in the affected parser and verify against the fixture. -Each parser has a `*_test.go` next to it using `testify`. Shared fixtures live in [test/resources/](test/resources/) (e.g. `pom.xml`, `package.json`, `requirements.txt`, `test_go.mod`, `Bootstrap.csproj`, `Gateway.csproj`, `packages.config`, `Directory.Packages.props`). When adding behaviors, add a fixture here rather than embedding large manifests in test source. +4. **Version resolves to `"latest"` unexpectedly:** check whether the version string matches a range specifier (`^`, `~`, `[`, `*`) or whether a lock file / properties file is present in the same directory as the fixture. -CI ([.github/workflows/ci.yml](.github/workflows/ci.yml)) enforces a **60% total coverage floor** โ€” adding an untested branch to an already-thin package can push the whole repo below the gate. +5. **New ecosystem not dispatched:** verify `selectManifestFile` in `manifest-file-selector.go` handles the new filename/extension and that the factory `switch` has a corresponding case. From 65f9b140ce0e51ff8af1d2e82cf4f28bf8cb1e7d Mon Sep 17 00:00:00 2001 From: cx-anurag-dalke <120229307+cx-anurag-dalke@users.noreply.github.com> Date: Mon, 13 Apr 2026 22:10:44 +0530 Subject: [PATCH 08/14] Add SBT (Scala Build Tool) manifest parser support Implement a production-grade SBT parser that extracts dependencies from all .sbt files (build.sbt, plugins.sbt, dependencies.sbt, etc.). The parser supports val/lazy val/def variable declarations, all SBT operators (%, %%, %%%), Seq blocks, addSbtPlugin syntax, dependency modifiers (exclude, excludeAll, intransitive, withSources, withJavadoc, cross, classifier), block and inline comments, scope annotations, dependencyOverrides, and duplicate package detection. Includes 29 unit tests at 97.8% coverage with test fixtures containing known-vulnerable packages (Log4Shell, Jackson, Struts2, commons-collections, SnakeYAML) for security scanning validation.

gradle: emit 0-based line numbers (was off-by-one, broke IDE decorations) - gradle: default empty catalog versions to "latest" (was causing 400 from realtime-scanner) - gradle: multi-line dependency locations with rawLines tracking - maven/dotnet/golang: strip trailing \r so byte offsets are correct on CRLF files - CLAUDE.md: strengthen 0-based contract, add SBT to parser list - plugins.sbt: add

All Python parsers return PackageManager="pypi" per design spec. Added testdata fixtures and comprehensive test coverage. Key changes: - Added internal/parsers/{poetry,setuptools}/ with full test suites - Enhanced internal/parsers/pypi/ with support for 6 Python formats - Fixed pre-existing CRLF line ending bug affecting golang, dotnet, maven on Windows - Updated manifest-file-selector.go with SBT, Poetry, and Setuptools routing - Updated parser_factory.go with dispatchers for all Python ecosystems - Updated CLAUDE.md with complete architecture and design pattern documentation All parsers pass unit tests. Manifest-parser builds and runs successfully.
