We present OptCD, a tool for optimizing continuous development (CD). Developers may mistakenly configure the CD workflow to generate unused files, such as code coverage reports, that are never uploaded anywhere for the developers to use before the files are destroyed. Generating unused files is a waste of time and effort that slows down the CD process. OptCD operates on Maven-based, Java projects that use GitHub Actions as their CD service, automatically identifying unnecessary files and directories that are generated or modified but never used afterwards. OptCD then pinpoints the Maven plugin (the process that performs build tasks for Maven) by analyzing the timestamps of generated files and matching against which plugin was running at that time. Finally, OptCD interfaces with Gemini, a large lan- guage model, to generate a fix to the Maven command contained within the CD configuration file to have the corresponding Maven plugin stop generating the unnecessary directories. Compared to our prior work, we (1) streamline and substantially simplify the process to use OptCD (e.g., reducing five steps that required nontrivial manual effort to one automated step) and (2) conduct an extensive evaluation of OptCD on 89 projects (compared to just 22 from before); OptCD is able to find 6800 unnecessary directories from 62 projects.
