Rebuild failure - skipping "after_assets_precompile" section of app.yml

S3 has been up and running on the site for 43 days. The rake commands were placed there as part of the S3 install.

The site has been rebuilt at least 30 times. I have added additional plugins and components along the way. This would indicate that .js files have been added and populated to the S3 bucket.

The S3 component has been working great. This is the first time I have had any issues with files not being migrated to S3.

What can I investigate to understand why the files were not moved?

Does anyone know what could cause the after_assets_precompile not to run?
