This PR optimizes the addGems functionality in GemExecutor by replacing a sequence of inefficient database operations (multiple reads, check-if-null, insert, multiple writes) with a single atomic INSERT INTO ... ON DUPLICATE KEY UPDATE query.

Performance Improvement:

  • Before: Each addGems call resulted in up to 6 database queries (Select gems, Select gems again, Insert if null, Select total, Update gems, Update total).
  • After: Each addGems call results in exactly 1 database query.

Verification:

  • Added GemExecutorTest which mocks MySQLManager and Gem plugin.
  • Verified that addGems is called exactly once and no other DB methods are invoked.
  • Verified that the build passes and tests succeed (after fixing PAPI dependency resolution).

Changes:

  • modules/Gem/src/main/java/com/mcatk/gem/sql/MySQLManager.java: Added addGems method.
  • modules/Gem/src/main/java/com/mcatk/gem/GemExecutor.java: Refactored addGems to use the new SQL method.
  • modules/Gem/src/test/java/com/mcatk/gem/GemExecutorTest.java: Added unit test.
  • modules/Gem/pom.xml: Added JUnit/Mockito dependencies and fixed PlaceholderAPI repo/version.
  • modules/Gem/src/main/java/com/mcatk/gem/Gem.java: Removed final keyword to allow mocking.

Optimize gem addition to use single atomic DB query
fbb6682 
Consolidated multiple SELECT/UPDATE/INSERT operations in GemExecutor.addGems into a single INSERT ... ON DUPLICATE KEY UPDATE query in MySQLManager. This reduces database round-trips from ~5-6 to 1 per transaction.

- Added MySQLManager.addGems(String, int)
- Updated GemExecutor.addGems to use the new method
- Added GemExecutorTest to verify optimization and correctness
- Fixed PlaceholderAPI repository URL and version in pom.xml to fix build
- Removed final modifier from Gem class to facilitate testing
