I'm trying to create a snap of camlistore -- the easiest way I've found is using the 'make' plugin. However, given the way that camlistore builds its artifacts -- all artifacts go into a /bin directory -- I haven't been able to get the artifacts in the snap without some modifications to snapcraft. I've tried two different scenarios, both of which fail. The first was just to set 'bin' as the artifact and have it copy the whole directory: ``` parts: camlistore: plugin: make artifacts: - bin ``` This fails because make uses file_utils.link_or_copy, not file_utils.link_or_copy_tree. The other thing I tried was passing each artifact individually -- like this: ``` parts: camlistore: plugin: make artifacts: - bin/cammount - bin/camget - bin/camput <snip> ``` This doesn't work either, because of file_utils.link_or_copy doesn't support creating nested directories prior to copying the files. I've thrown together a PR to adddress both scenarios, which I'll submit once I file this. I'm not sure if I took the best approach, but the changes are this: . For the first scenario, have the make plugin check if the artifacts specified represent a directory, and, if so, use file_utils.link_or_copy_tree instead . For the second issue, modify file_utils.link_or_copy to create subdirectories if the directory of the destination object doesn't exist.
