Resolution: closed resolved
Reason: The maintainer stated that ubuntu-core/snapcraft#368 would also fix this problem; that PR was merged in commit f4f02c0d2 and updated the libpipeline test expectation.

Issue body
<mterry> elopio, um, if I recall, it was to demonstrate that snapcraft could integrate with your locally built project too. Like you have your source tree. And then you had snapcraft grab all the dependencies and build them. And then you could run "snapcraft shell make" to build your local project pointing at the snapcraft built files. I don't know whether that concept meshes with the snapcraft of today anymore
<mterry> elopio, (i.e. to demonstrate that you could build that local test.c against snapcraft's copy of libpipeline)
This test is successfully using the remote lp:~mterry/libpipeline/printf, but it's also using the remote lp:~mterry/+junk/pipelinetest and totally ignoring the local files test.c and Makefile.
We should either change the libpipeline part to use the local files, or remove them.
In addition to this, the test uses ls to test the pipeline. Now that the snap's cwd is empty, ls doesn't make a lot of sense anymore. See https://bugs.launchpad.net/snapcraft/+bug/1554637

| qwen/qwen3.6-35b-a3b | — | — | Closed without resolution. The issue flagged inconsistencies in the libpipeline example, noting it ignored local files for remote branches and used an outdated ls command in an empty working directory. No changes were made. |
