Project Introduction

Summary

PMD is a robust open-source static analysis tool that inspects source code and reports on issues such as potential bugs, dead code, code complexity, and suboptimal code structure. Its extensibility makes it highly adaptable to different project needs.

Problem Solved

Developers and teams often face challenges in maintaining code quality, consistency, and identifying potential runtime issues early. PMD addresses this by automatically scanning code for common pitfalls, bugs, dead code, and style violations before deployment.

Core Features

Multilanguage Support

Analyzes source code in multiple languages including Java, C++, C#, XML, XSL, Apex, Visualforce, PLSQL, Salesforce.com Apex and Visualforce, etc.

Extensible Rule Set

Allows users to write custom rules to enforce specific coding standards or find domain-specific issues.

Comprehensive Reporting

Provides various reports (XML, HTML, CSV, etc.) that can be integrated into build processes.

Duplicate Code Detection (CPD)

Includes Copy/Paste Detector (CPD) to find duplicated code.

Tech Stack

Java
ANTLR
Maven

Use Cases

PMD can be integrated into various stages of the software development lifecycle to enforce quality standards and find issues proactively.

CI/CD Pipeline Integration

Details

Integrate PMD into your CI pipeline (e.g., Jenkins, GitLab CI, GitHub Actions) to automatically analyze every code commit or pull request.

User Value

Catches issues early, prevents low-quality code from being merged, automates code review.

Analyzing Legacy Code

Details

Run PMD on existing large codebases to identify areas of high complexity, potential bugs, or violations of desired coding practices.

User Value

Helps understand and refactor complex parts of legacy systems, reduces risk when modifying old code.

Enforcing Coding Standards

Details

Define custom rules specific to your project or organization's coding standards and use PMD to automatically check compliance.

User Value

Ensures consistency across the codebase, reduces friction during code reviews related to style or common patterns.
