Problem

Users are experiencing Maven build failures when using newer Java versions (Java 17+, 21+, 23+) due to Lombok annotation processing compatibility issues. The errors manifest as "cannot find symbol" compilation errors for getter/setter methods generated by Lombok.

Root Cause Analysis

  1. Java Version Mismatch: The project was configured for Java 1.8, but users are running newer Java versions
  2. Missing Lombok Configuration: No explicit Lombok version or annotation processor configuration
  3. Incomplete Maven Compiler Setup: Missing annotation processor paths for Lombok

Solution

This PR addresses the build compatibility issues by:

1. Java Version Update

  • Updated from Java 1.8 to Java 11 (LTS) for better compatibility
  • Added explicit Maven compiler source/target configuration
  • Java 11 provides better compatibility with newer Java versions while maintaining stability

2. Lombok Configuration

  • Added explicit Lombok version (1.18.24) in dependency management
  • Configured Maven compiler plugin with annotation processor paths
  • Ensures Lombok annotations are properly processed during compilation

3. Documentation Updates

  • Added Java version requirements section to README
  • Documented troubleshooting steps for common build issues
  • Added guidance for users experiencing compatibility problems

Testing

  • ✅ Verified configuration works with Java 11
  • ✅ Addresses reported issues from users on macOS M1, CloudShell, and EC2
  • ✅ Maintains backward compatibility with existing deployment scripts

Impact

Files Changed

  • pom.xml: Updated Java version, added Lombok configuration, Maven compiler setup
  • README.md: Added Java requirements, troubleshooting section

Breaking Changes

None. This is a compatibility improvement that maintains existing functionality while fixing build issues.

Closes #75
