``` Once a project is re-run, snapcraft loses metadata generated from scripts (i.e. snapcraftctl set-version and set-grade). Snapcraft itself will reproduce this issue when the sources change: ``` Skipping stage bash-completion (already ran) Skipping stage snapcraft-libs (already ran) Skipping stage legacy-snapcraft (already ran) Skipping stage patchelf (already ran) Cleaning later steps and re-staging snapcraft ('build' step changed) Skipping prime bash-completion (already ran) Skipping prime snapcraft-libs (already ran) Skipping prime legacy-snapcraft (already ran) Skipping prime patchelf (already ran) Priming snapcraft Compiling pyc files... Failed to generate snap metadata: 'adopt-info' refers to part 'snapcraft', but that part is lacking the 'parse-info' property. ``` - Since version information may have changed between runs, we now re-execute the override-pull scriplets when the pull step is re-run. - Track current step in pluginhandler when invoking a step inside the runner - we can use this to determine which scriplet metadata to update once called. The previous logic assumed that the steps were cleaned and not being re-run when checking for metadata duplication. - Add test to reproduce failure (and pass it!) LP #1790651 ```
