BUMP: A Benchmark of Reproducible Breaking Dependency Updates

Bump is a benchmark of breaking dependency updates. A breaking update is defined as a pair of commits for a Java project, which we designate as the pre-commit and the breaking-commit. When we build the project with the pre-commit, compilation and test execution are successful, while the build of the breaking-commit fails. Each breaking-commit is a one-line change in the Maven pom file.Bump是一款针对依赖更新破坏性变更的基准数据集。所谓破坏性依赖更新，指的是针对Java项目的一对提交（commit），我们将其分别定义为前置提交（pre-commit）与破坏性提交（breaking-commit）。使用前置提交构建该项目时，编译与测试执行均可顺利完成；而使用破坏性提交构建时，项目构建则会失败。每一处破坏性提交仅对Maven的pom文件进行了单行修改。
