Sometimes, between fetching an index and downloading the actual package, there's an update to a package, which causes a checksum mismatch. This has been causing macos build failures. Clearing the package cache before `conda build` helps prevent this failure from happening. We also add retry logic so that if the upstream race condition occurs during the actual build, it will hopefully succeed the next time. Signed-off-by: Patrick Avery <patrick.avery@kitware.com>

I'm gonna try running the CI 3 times to verify the spurious error doesn't happen again, at least in this PR. It's running the first time now. |

Strangely, the code coverage is reduced, even though only CI code was modified 🙂 |

Second time passed. It succeeded during its second attempt (first attempt had the error). |

Clearing the package cache before
conda buildhelps prevent this failure from happening. We also add retry logic so that if the upstream race condition occurs during the actual build, it will hopefully succeed the next time.I think it is mainly happening for mac because we include a cross-compile, and thus build 10 packages in one CI run. I think
conda buildcaches the hashsum values early on in the process, and if the packages get updated upstream during the 10 builds, the hashsum no longer matches and it fails.Affected Workflows
