| # Cache build and external artifacts so that the next ci build is incremental. | |
| # Because github action caches cannot be updated after a build, we need to | |
| # store the contents of each build in a unique cache key, then fall back to loading | |
| # it on the next ci run. We use hashFiles(...) in the key and restore-keys- with | |
| # the prefix to load the most recent cache for the branch on a cache miss. You | |
| # should customize the contents of hashFiles to capture any bazel input sources, | |
| # although this doesn't need to be perfect. If none of the input sources change | |
| # then a cache hit will load an existing cache and bazel won't have to do any work. | |
| # In the case of a cache miss, you want the fallback cache to contain most of the | |
| # previously built artifacts to minimize build time. The more precise you are with | |
| # hashFiles sources the less work bazel will have to do. | |
