42-53: Enhance test coverage with edge cases and error handling.The test correctly verifies basic functionality, but consider adding tests for edge cases such as:
- Missing or corrupted JSON file
- Empty targets array
- Null config handling
Add these additional test methods:
@Test public void testGetTargetsWithNonExistentFile() { EspConfigParser parser = new EspConfigParser("non-existent-file.json"); Set<String> targets = parser.getTargets(); assertNotNull(targets); assertTrue(targets.isEmpty()); } @Test public void testGetBoardsConfigsWithNonExistentTarget() { EspConfigParser parser = new EspConfigParser(tempJsonFile.getAbsolutePath()); Map<String, List<String>> configs = parser.getBoardsConfigs("non-existent-target"); assertNotNull(configs); assertTrue(configs.isEmpty()); }bundles/com.espressif.idf.core/src/com/espressif/idf/core/util/EspConfigParser.java (2)
41-59: Enhance error handling with more specific logging.The error handling is good but could be more informative. Consider logging the specific error type and providing more context.
Apply this diff to improve error logging:
private EspConfig loadConfig() { File file = new File(espConfigPath); if (!file.exists()) { - Logger.log("esp-config.json not found at: " + espConfigPath); //$NON-NLS-1$ + Logger.log("esp-config.json not found at: " + espConfigPath + ". Using empty configuration."); //$NON-NLS-1$ return null; } try (FileReader reader = new FileReader(file)) { return gson.fromJson(reader, EspConfig.class); } catch (IOException e) { - Logger.log(e); + Logger.log("Failed to parse esp-config.json at: " + espConfigPath + ". " + e.getMessage(), e); //$NON-NLS-1$ return null; } }
115-139: Consider adding validation annotations for better data integrity.The nested classes correctly model the JSON structure, but consider adding validation annotations to ensure data integrity during deserialization.
Apply this diff to add validation:
+import com.google.gson.annotations.SerializedName; + private static class EspConfig { + @SerializedName("targets") List<Target> targets; + @SerializedName("options") List<Option> options; + @SerializedName("boards") List<Board> boards; } private static class Target { + @SerializedName("id") String id; } private static class Option { + @SerializedName("name") String name; + @SerializedName("values") List<String> values; } private static class Board { + @SerializedName("name") String name; + @SerializedName("target") String target; + @SerializedName("config_files") List<String> config_files; }

26-40: LGTM! Clean test setup with proper resource management.The test setup correctly copies the resource file to a temporary location and ensures cleanup with
deleteOnExit(). The try-with-resources statement properly handles file operations.bundles/com.espressif.idf.core/src/com/espressif/idf/core/util/EspConfigParser.java (2)
24-39: LGTM! Excellent refactoring with proper caching and constructor overloading.The addition of configuration caching and constructor overloading improves both performance and testability. The immutable fields ensure thread safety after construction.
61-75: LGTM! Robust implementation with proper null safety.The method correctly handles null config and null targets with appropriate fallbacks. The use of LinkedHashSet maintains insertion order while preventing duplicates.

Verify ESP32-C61 target definition is included.
The ESP32-C61 target is referenced in board configurations but is not defined in the targets array. This inconsistency may cause issues when validating target-board relationships.
Run the following script to verify target consistency:
🏁 Script executed:
#!/bin/bash
# Description: Check for target consistency between targets array and board configurations
# Extract targets from JSON and check if all board targets are defined
cat tests/com.espressif.idf.core.test/resources/esp-config.json | jq -r '.targets[].id' | sort > /tmp/defined_targets.txt

Add missing ESP32-C61 target definition
The JSON lists a board with "target": "esp32c61" but the targets array (lines 3–12 in tests/com.espressif.idf.core.test/resources/esp-config.json) has no entry for esp32c61. This mismatch will break target-board validation.
Please update the targets array to include an entry for ESP32-C61. For example:
{ "id": "esp32c6", "name": "ESP32-C6", "idcode": "0x0000dc25" },
+ { "id": "esp32c61", "name": "ESP32-C61", "idcode": "<correct_idcode>", "ocdid": "<correct_ocdid>" },
{ "id": "esp32h2", "name": "ESP32-H2", "idcode": "0x00010c25" },– Replace <correct_idcode> and <correct_ocdid> with the values from the ESP-IDF documentation.

In tests/com.espressif.idf.core.test/resources/esp-config.json around lines 3 to
12, the targets array is missing an entry for the esp32c61 target, which is

esp32c61 with the correct id, name, idcode, and ocdid values as per ESP-IDF
documentation to the targets array to fix the mismatch.

Missing interface field in ESP32-C61 board configurations.
The ESP32-C61 board configurations (lines 251-273) are missing the interface field, while other board configurations include this field. This inconsistency may cause issues when the parser expects interface information.

to 273, the ESP32-C61 board configurations lack the required "interface" field

Description
The goal of this PR is to optimize EspConfigParser by using faster gson instead of json-simple, load the config file only once in the constructor, and avoid unnecessary exceptions like java.io.FileNotFoundException: \esp-config.json (The system cannot find the file specified)
