try to publish the easy example to confluence

Hi there,

i would like to ask for assistance. It was very easy (and a nice experience, too ❤️ ) to follow the simple Tutorial on https://docs-as-co.de/getstarted --> The Build-Tool Approach --> Gradle.

calling the asciidoctor task (see below) created the test.html file

After having created the test.html file i wanted to publish that to confluence.

I researched the gradle plugin https://plugins.gradle.org/plugin/de.docs-as-co.publishToConfluence ... but i was not able to find out how to configure it. ... I also looked at http://doctoolchain.org/docToolchain/v2.0.x/015_tasks/03_task_publishToConfluence.html#_configuration ... and tried that ... but i am not doing it the right way 😢

Could you/someone maybe answer with a (configured the right way way 🤷 ⁉️ ) gradle task config for my build.gradle file for the following setup: (the part in the task `asciidocToConfluence` seems to be improvable 😅 )

Thank you in advance, if you maybe be able to help me!

As an alternative: do you know any github repos that show a working setup for "publishing to confluence"? I then could look at that, and maybe repair it myself ✊

```groovy
asciidoctor {
// sourceDir file('docs/asciidoc')
// sources {
// include 'toplevel.adoc', 'another.adoc', 'third.adoc'
// }
// outputDir file('build/docs/asciidoc')
}

asciidocToConfluence {

input = [
[ file: "build/docs/asciidoc/test.html" ],
]

// endpoint of the confluenceAPI (REST) to be used
api = 'https://confluence.host.url/rest/api/'

// the key of the confluence space to write to
spaceKey = '$CONF_SPACE_KEY'

// variable to determine whether ".sect2" sections shall be split from the current page into subpages
createSubpages = false

// the pagePrefix will be a prefix for each page title
// use this if you only have access to one confluence space but need to store several
// pages with the same title - a different pagePrefix will make them unique
pagePrefix = 'Testtest - '

// username:password of an account which has the right permissions to create and edit
// confluence pages in the given space.
// if you want to store it securely, fetch it from some external storage.
// you might even want to prompt the user for the password like in this example

credentials = "$user:$password".bytes.encodeBase64().toString()
}
```

Start with the build.gradle snippet, the asciidocToConfluence task, and the linked publishToConfluence configuration documentation. Compare the task settings with the Gradle plugin and docToolchain examples; done means a documented working configuration for publishing test.html to Confluence or a linked repository showing one.
