SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This skill addresses the challenge of ensuring backward compatibility and identifying breaking changes when updating Java libraries, preventing unexpected runtime errors and simplifying API evolution.

Core Features & Use Cases

  • API Comparison: Compares method signatures, class definitions, and interface changes between two versions of Java libraries.
  • Breaking Change Detection: Identifies removed APIs, incompatible signature modifications, and parameter count changes.
  • Detailed Reporting: Generates a JSON report categorizing issues into breaking changes, warnings, and informational messages, including migration guidance.
  • Use Case: Before upgrading a core Java library in a large project, use this skill to automatically scan for any API incompatibilities introduced in the new version, allowing developers to proactively address them.

Quick Start

Validate the API consistency between the old and new versions of a Java library by running the validation script with their respective paths.

FAQPage Schema
How do I detect breaking changes in Java libraries?

To detect breaking changes in Java libraries, perform static analysis comparing method signatures, class definitions, and interface changes between the old and new versions to identify backward-incompatible modifications like removed APIs or altered parameter types.

What is Java API consistency validation?

Java API consistency validation is a static analysis process that compares method signatures, class definitions, and exception declarations between two library versions to ensure backward compatibility and prevent unexpected runtime errors during upgrades.

How do I check Java library backward compatibility before an upgrade?

To check Java library backward compatibility, run a validation script with the respective paths of the old and new library versions to scan for API incompatibilities, allowing developers to proactively address migration issues.

Does API consistency validation identify incompatible signature modifications?

Yes, API consistency validation identifies incompatible signature modifications by comparing parameter types, return types, and parameter counts across library versions, categorizing detected issues into breaking changes and warnings.

Can I generate a JSON report for Java API breaking changes?

Yes, you can generate a detailed JSON report for Java API breaking changes that categorizes issues into breaking changes, warnings, and informational messages, while also providing specific migration guidance for resolved incompatibilities.

What are the limitations of static analysis for Java API consistency?

Static analysis for Java API consistency is limited to evaluating code structure like method signatures and class definitions, meaning it cannot detect runtime behavioral changes or dynamic reflection issues not visible in the static source code.
