Recently the scenario of editing project source code locally but building the project remotely on another machine (for example inside a Docker container or an Amazon Web Services host) is becoming more common. The setup typically involves starting a build from Emacs that first uses
rsync to copy over the project directory to a remote host and then execute the build command there.
A problem arises however when there is a build error and the reported remote source code file paths do not match the paths on the local host. In this case Emacs' compilation mode is not able to automatically jump from the error to the local file (because it doesn't understand how to map the remote path to the local path). How can the Emacs compilation mode be configured to convert the remote paths to local paths?
Possibly the user would have to provide some basic remote path to local path mapping function. Or maybe some heuristic could be implemented which tries mapping only the part of the path relative to the project directory, which should be the same on the local and remote host.
