Help! Transformation failed: The requested module could not be built in Java 8 sandbox.

## System details (run the `AWS: About Toolkit` command)

- OS: Linux x64 5.15.0-52-generic
- Visual Studio Code version: 1.86.0
- AWS Toolkit version: 2.8.0

## Question

Hi everyone, good afternoon.

I'm trying to use the toolkit in order to help us migrate a legacy project from Java 8. I'm aware that Amazon Q is under preview mode, so I don't expect a full transformation to be executed properly. But it would be good to see what we can get.

However, even that I had double-checked my build locally as we can see on the screenshot ('BUILD SUCCESS'), it says that the transformation failed. I also increased the log-level to DEBUG for the toolkit to see if I was able to get more detailed messages, but that didn't help that much.


Am I missing something? Is there a way that I can have more details regarding that message? If so, it would be good, so I can play around here and try again.

Thank you,
Regards.

Start with the AWS: About Toolkit command output and the DEBUG logs for the Java 8 sandbox transformation, then reproduce the reported build-success/failure case. Done means the failure has actionable diagnostic details or a confirmed cause and documented resolution.
