The bug-mining test reproduces bug mining for commons-codec, a project in D4J. While it creates a new project and creates all mined data outside of D4J, it deletes the commons-codec git repo under project_repos (as opposed to the temporary location) at the end.
A workaround is to extract the commons-coded repo from the downloaded archive under project_repos after running the test.
