Cache not storing output artifacts in CI environment (using powerpack-shared-fs-cache)

[gabrielbryk]

Current Behavior

When using powerpack-shared-fs-cache in a CI environment (or with CI=1), the cache system:

• Creates entries in shared.db correctly
• Stores terminal outputs successfully
• Creates output asset folders
• Does not persist output artifacts in the folders
• (When testing locally) Briefly creates output files but immediately deletes them

Expected Behavior

The powerpack-shared-fs-cache should:

• Properly store and persist output artifacts in CI environments
• Maintain cached files in the designated folders
• Behave consistently between local and CI environments

GitHub Repo

Not sure how to do this as it is reliant on a paid feature (powerpack)

Steps to Reproduce

1. Set up a project using NX with powerpack-shared-fs-cache
2. Configure cache settings in nx.json
3. Set environment variable CI=1
4. Run a build command that generates output artifacts
5. Observe that while the cache entries are created, the output artifacts are not persisted

Operating System

• macOS
• Linux

• Other (Please specify)

Additional Information

• Cache behavior works correctly in local environment without CI=1
• Documentation doesn't mention any limitations for CI environments
• The issue appears to be specific to file artifacts, as terminal outputs are cached correctly
• Observed temporary file creation before deletion suggests a potential cleanup mechanism interfering with cache persistence
