Authentication Failed error when downloading maven dependencies

If you get an error when trying to download the ChestShops or RegionProtection dependency:

You'll need to modify your ~/.m2/settings.xml if on Linux. If you're on WIndows, I think it'll be in C:\Users\<username>\.m2\settings.xml.

You'll need to set it to:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd">
  <servers>
    <server>
      <id>github</id>
      <username>[GITHUB USERNAME]</username>
      <password>[TOKEN]</password>
    </server>
  </servers>
</settings>

Where [GITHUB USERNAME] is your GitHub username and [TOKEN] is a personal access token generated in GitHub.

You can read more about the settings.xml here
