Issues with Compiling Latest Version (demo)

[Swamp2k9]

What are you trying to achieve?

I've downloaded the latest build with the hopes of testing the new demo, but I'm receiving the below error when compiling:

Could not create task ':mkdocsBuild'.
Cannot get property 'base_tag' on extra properties extension as it does not exist

1. Download the latest release (.zip)
2. Unzip
3. Open Intellij Idea
4. Open project folder in Intellij Idea
5. Wait for project to build
6. See error message

What have you tried?

I've tried changing Gradle versions.

Additional context

I've used the steps here to download the .apk directly.

The error is because jgitver is attempting to find the version through git tags, but you haven't cloned the git repo.

Instead of downloading a .zip, git clone the repo.

That did the trick! Thanks for your help and quick reply!
