Troubleshooting

The following offers some solutions to common issues when setting up and using Athena. If you come across any issues that you think belong here, please feel free to contribute.

General

The Athena logs are Jetty logs, so they can be found wherever your Jetty instance stores its logs.

The logs have a lot of information and should help indicate the error. More info on logging levels

Checkstyle Error - "Extra lines between braces [RegexpMultiline]"

This is an Athena-custom checkstyle rule which simple disallow the following code snippet:

    }

}

Basically, multiple lines between right curly braces is defined as a checkstyle violation. The error, however, might still pops up with something visually like this:

    }
}

Note that no extra line can be seen in this reported case. The most probably cause might be a shared development environment where one team member wrote code on Windows, which uses CRLF line endings, and the other uses UNIX/Mac. We should replace all CRLF endings with UNIX '\n' endings.
