Exception while rendering single Jinja file

[vlotorev]

Collections configuration in conf.py contents:

collections = {
    "plugins": {
        "driver": "jinja",
        "source": "plugins.rst.jinja",
        "data": {
            "title": "Some title",
            "plugins": plugins,
            "projects": projects,
        },
        "target": "plugins.rst",
    },
}

Output:

sphinx-build -b html doc build/html-doc

Traceback (most recent call last):
  File ".../lib/python3.6/site-packages/sphinxcontrib/collections/drivers/jinja.py", line 122, in run
    with open(target, 'w') as target_file:
IsADirectoryError: [Errno 21] Is a directory: '...doc/_collections/plugins.rst'

The issue is:

• Collection constructor creates new directory for target:

  sphinx-collections/sphinxcontrib/collections/collections.py

  Line 102 in 3c48b25

  os.makedirs(target, exist_ok=True)

• but Jinja driver tries to write rendered contents to the same target:

  sphinx-collections/sphinxcontrib/collections/drivers/jinja.py

  Line 122 in 3c48b25

  with open(target, 'w') as target_file:
