Specifying conda-environment=<file> in cirrus.conf does not work

[jordansamuels]

Even if you specify e.g.

[build]
builder = CondaEnv
conda-environment = environment.yml

in cirrus.conf, you still get:

RuntimeError: No conda environment yaml specified in cirrus.conf [build] section or via --environment option

when you run conda build . The workaround is to specify on command line conda build --environment=environment.yml .

The reason this appears to be happening is that in conda_env.py, this code

        self.plugin_parser.add_argument(
            '--environment',
            help='conda environment file to process',
            default=None
        )

causes the lookup here

        environment = kwargs.get(
            'environment',
            self.build_config.get('conda-environment', None)
        )

to fail, because the kwargs['environment'] = None so the build_config.get is never invoked.
