Are automated static analysis tools worth it? An investigation into relative warning density and external software quality on the example of Apache open source projects

This is the dataset for the publication "Are automated static analysis tools worth it? An investigation into relative warning density and external software quality on the example of Apache open source projects". It contains just-in-time defect-prediction style data in jit_data2.tar.gz as well as warnings generated by PMD 6.31.0 in warnings_data3.tar.gz. Further information and scripts for generating the plots and tables can be found in the replication kit.本数据集对应学术论文《自动化静态分析工具（automated static analysis tools）是否物有所值？以Apache开源项目为例的相对警告密度与外部软件质量调查》。其中jit_data2.tar.gz包含即时缺陷预测（just-in-time defect-prediction）类数据，warnings_data3.tar.gz存储了PMD 6.31.0生成的静态分析警告信息。相关补充资料以及用于生成图表与表格的脚本均可在复现套件（replication kit）中获取。
