Cascading Effects: Analyzing Project Failure Impact in the Maven Central Ecosystem

This study examines failure propagation patterns within the Maven Central ecosystem, a critical software dependency repository, through a comprehensive analysis of dependency networks using the Goblin framework. Our dual-sampling methodology, investigating both top dependencies and random libraries, revealed two distinct failure propagation patterns that pose significant risks to ecosystem stability. Core infrastructure failures, particularly evident in cases like the AWS SDK family, can create immediate and widespread disruption.

本研究依托Goblin框架（Goblin framework），通过对软件依赖网络的全面分析，探究了作为关键软件依赖仓库的Maven中央仓库生态系统（Maven Central ecosystem）内的故障传播模式。本研究采用的双采样方法同时覆盖核心依赖与随机选取的开源库，由此揭示了两种对生态系统稳定性构成显著威胁的差异化故障传播模式。核心基础设施故障——尤以AWS软件开发工具包（AWS SDK）家族相关案例为典型——可引发即时且大范围的服务中断。
