Jekyll post not generated

Question

I am trying to add a new post to my Jekyll site, but I cannot see it on the generated pages when I run jekyll serve.

What are some common reasons for a

Answer 1

One possible reason is that the date specified in the front matter does not contain a time zone offset, in which case it defaults to UTC, not the time zone of the local machine as you might expect. I wasted an hour on this until UTC "caught up" with my current local time zone, BST.

I haven't found a definitive answer to this but I think the date in the front matter must be given in UTC with a timezone offset (which defaults to zero if omitted).

So date: 2018-05-03 12:34:27 is in UTC irrespective of where in the world you are, and irrespective of the timezone setting in _config.yml.

So be careful to specify datetimes like this:

date: 2018-05-03 12:34:27 +0100

Answer 2

If you have checked your front matter, and all seems well, and even jekyll build --verbose doesn't reveal anything (in my case, it just acted as if the file didn't exist at all, not even listing it as excluded), check the encoding of your file. Apparently, it needs to be UTF-8 without signature. It it's UTF-8 BOM (or UTF-8 with Signature as some text editors call it), then it will be silently ignored. To make matters worse, some editors will display both types as just UTF-8, making the difference even harder to spot.

Answer 3

• The post is not placed in the _posts directory.
• The post has incorrect title. Posts should be named YEAR-MONTH-DAY-title.MARKUP (Note the MARKUP extension, which is usually .md or .markdown)
• The post's date is in the future. You can make the post visible by setting future: true in _config.yml (documentation)
• The post has published: false in its front matter. Set it to true.
• The title contains a : character. Replace it with &#58. Works in jekyll 3.8.3 (and probably in other 'recent' releases).

Answer 4

My post also did not appear an the error was, that in my name I used a dot, e.g. 2017-10-18-test.2.md.
This is not accepted, you have to use 2017-10-18-test2.md.

You can use jekyll build --verbose to view build process in detail.

Exmaple output:

from the log I found jeklly skipped 2018-01-14-boot-android-on-charge.md because it has a future date.

Or it can be browser cache as well if you are looking not in the _site folder but directly on the blog's main page with the list of posts.
