Do you have the full trace? As far as I know the repository URL is listed in the trace, but not exactly where you would expect.

Some discussion points:

The PR is at best a work-around. Ideally the deployer's resource resolution should have proper (abstracted) exception handling defined.

At present the Deployer SPI does not define exception handling well. We use the super generic org.springframework.core.io.Resource class backed by the generic ResourceLoader so that everything is abstracted away. Unfortunately, those classes don't define exception handling.
