Error message not pointing to problem

[cdeil]

I have this case: https://travis-ci.org/gammapy/gammapy/builds/230082206?utm_source=github_status&utm_medium=notification saying

The log message was: Build config file had a parse error: did not find expected '-' indicator while parsing a block collection at line 158 column 5.

But really there's no problem on that line and it's a SyntaxError further down on line 175, no?

Can you make travis-yaml give a better message here pointing to the actual line with the issue?

The error on the line 175 alters the parser's expectation of the data structure that starts on line 158.

Unfortunately, our YAML parser stops parsing the file upon the first error.

http://yaml-online-parser.appspot.com/, which uses the pyyaml, shows the same error, and also the one on line 175. I am not familiar with yamllint, but https://pypi.python.org/pypi/yamllint says that it is not a validator.

Thanks for the quick reply! I just thought I'd mention it. Feel free to close if there's nothing you can do here with reasonable effort.
