Apache Java Projects with Code, Dependencies, and Pull Requests for Technical Debt Study

A 1.2 GB dataset of mature open-source Java projects from the Apache Software Foundation, selected for their diverse use of third-party libraries. It includes source code, dependency information, and GitHub pull request discussions, with static analysis results from PMD and Designite to capture code- and design-level technical debt indicators. The dataset was created by Ciprian-Viorel Stupinean and last updated on 2026-04-25.

Use Cases

• Identify code-level technical debt indicators based on static analysis results from PMD.
• Analyze design-level technical debt indicators based on static analysis results from Designite.
• Study the relationship between third-party library usage and technical debt based on dependency information.
• Examine socio-technical signals related to library-induced debt based on GitHub pull request discussions.

Strengths

• Includes source code, dependency information, and pull request discussions for a multi-faceted analysis.
• Static analysis results from two tools (PMD and Designite) provide both code- and design-level debt indicators.
• Projects are mature and from the Apache Software Foundation, suggesting a degree of quality and real-world relevance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect bias inherent to the selected Apache projects and the figshare platform.
