Is there a way to upload a Maven settings.xml to Bitrise and use it in a workflow without committing the file to source control? We need access a secured Maven Repository to retrieve a private dependency.
Sure, you can use e.g. the “Generic File Storage” on bitrise.io to upload/store the file, and use a File Downloader step to download it during the build to the location you want to.
Please see my related comment/answer for more details at: Adding/overwriting configuration files (secrets, gitignored, not in repository)
