BUG: Tilt Up fails if build cache is used due to failed Docker builds

[ewilkins-csi]

Description

Any time a project with Docker images is built and has a hit in the Maven build cache for any of the Docker modules, project deployment fails because those modules don't have the appropriate files staged in the target directory.

Steps to Reproduce

1. Create a new project
2. Add a simple data-delivery pipeline example
3. Run ./mvnw clean install and follow manual actions
4. Repeat until there are no more manual actions printed
5. Deploy the project with tilt up
6. Note that the builds for project images fail with the following error:

Build Failed: ImageBuild: failed to compute cache key: failed to calculate checksum of ref 2ffefd1f-cac0-4055-b6ea-1eb13255fccc::v8ge44kfavcvmfkbw0mkdxkzd: failed to walk /var/lib/docker/tmp/buildkit-mount1603518359/target: lstat /var/lib/docker/tmp/buildkit-mount1603518359/target: no such file or directory

Expected Behavior

After tilt up, all resources start successfully in the Tilt dashboard.

Actual Behavior

Any resources that deploy project Docker images fail. E.g.:

• policy-decision-point
• spark-worker-image
