Review Summary
The Java implementation is solid with proper logging calls and no System.out.println statements remaining. However, the log4j2.xml or log4j2.properties configuration file that configures File and Console appenders is missing from src/main/resources/. This is a core task requirement — the task explicitly states "configure the logger with File and Console appenders" and without this configuration file, the logging cannot function as specified. Please add a log4j2.xml file to src/main/resources/ that defines both a <Console> appender and a <File> appender (e.g., writing to logs/app.log), and ensure the Root logger references both appenders. Minor checkstyle EmptyLineSeparator violations (missing blank lines before method definitions in Main.java and AuthenticationServiceImpl.java) can be addressed based on linter feedback.

Missing log4j2 configuration file. The task requires configuring the logger with File and Console appenders, but no log4j2.xml or log4j2.properties file exists in src/main/resources/

Excessive blank line - multiple consecutive blank lines (lines 1, 2) reduce code readability

Review Summary
Your solution is approved. All core functional requirements are met: logging is properly implemented across all Java files, all System.out.println() and e.printStackTrace() statements have been replaced with logger methods, no TODO comments remain, and the logs/* directory is correctly excluded in .gitignore. The log4j2.xml configuration file appears in your changed files, which is essential for the logging framework to function. Minor style issues (EmptyLineSeparator violations) may exist but are linter-addressable. The variable naming inconsistency (log vs logger) across classes is a cosmetic preference rather than a functional issue. Your implementation demonstrates a solid understanding of logging requirements.
