Can I suggest that for questions like this, you let us know what Gerrit version you are running, and also show us the exact command you are issuing, and the exact error message.
If I understand the documentation correctly, you can retrieve the contents of a specific file (if you know the path to it), but there is no facility to get a list of files.
This worked for me:
- The project name (gda/gda-core) has a slash in it, which needs to be encoded as %2F
- Ditto for the file path
- This project can be read anonymously - otherwise, the URL needs to reference the authenticated endpoint (https://gerrit.server/a/).
- The result returned is base64 encoded.
Is there a reason not to just clone the repo and inspect the local copy?
