From 861bfa1745de0658a9817e7cd16aaa0f31664182 Mon Sep 17 00:00:00 2001 From: Ubuntu Date: Tue, 3 Feb 2026 17:31:23 +0000 Subject: [PATCH 01/12] feat: add comprehensive Gradle build tool support for Java Adds full Gradle support to CodeFlash Java implementation, enabling optimization of Gradle-based Java projects alongside existing Maven support. Changes: - Add GradleTestResult dataclass for test execution results - Implement run_gradle_tests() with support for: - Running all tests or specific test classes/methods - Multi-module Gradle projects - JaCoCo coverage collection - Gradle wrapper (gradlew) detection - Implement compile_with_gradle() for compilation - Add _parse_gradle_test_results() for JUnit XML parsing - Update find_gradle_executable() to accept project_root parameter - Update detect_build_tool() to handle both Path and string inputs - Extend _find_multi_module_root() to detect Gradle multi-module projects: - Parse settings.gradle and settings.gradle.kts files - Extract module names from include statements - Support both Groovy and Kotlin DSL - Create build tool dispatcher in _run_maven_tests() - Add _run_gradle_tests_impl() for Gradle test execution - Add comprehensive test suite with 21 tests covering: - Test execution (all tests, specific classes/methods) - Multi-module project support - Compilation - Error handling and timeouts - JaCoCo coverage collection All tests passing (21/21 in test_gradle_support.py).

Many projects (like Elasticsearch) don't have this. This change uses the JaCoCo agent approach instead, which: - Downloads JaCoCo agent JAR dynamically via get_jacoco_agent_jar() - Injects coverage collection via JAVA_TOOL_OPTIONS environment variable - Works with any Gradle project without build file changes - Eliminates dependency on jacocoTestReport Gradle task Changes: - build_tools.py: Replace jacocoTestReport task with JaCoCo agent injection - test_runner.py: Add Gradle-specific coverage path handling - test_gradle_support.py: Update test to check for agent env vars instead of task Fixes optimization failures on projects without JaCoCo plugin configured.

Previously, CodeFlash placed all tests in the project root's `test/` directory, causing Gradle to search for tests in all modules and fail with "No tests found" errors. Changes: - build_tools.py: Enhanced find_test_root() to accept source_file_path parameter - Detects which module the source file belongs to (e.g., "server" from "server/src/main/...") - Returns that module's test directory (e.g., "server/src/test/java") - Falls back to existing behavior if source file not in a module - function_optimizer.py: Updated _fix_java_test_paths() to use module-aware test root - Calls find_test_root() with source file path - Places generated tests in the correct module's test directory - Ensures `:server:test --tests` runs instead of `test --tests` (all modules) This fixes optimization failures on multi-module Gradle projects where tests were placed in the wrong location and couldn't be found by the build tool.
