Jitpack.io not finding dependency

Question

I am currently trying to use a GitHub project as a maven dependency but I always get the Could not find artifact com.github.WolfyScript:CustomCrafting:pom:master-SNAPSHOT in mavenCentral (https://repo1.maven.org/maven2/) line. My pom.xml looks as follows:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://maven.apache.org/POM/4.0.0"

            <version>master-SNAPSHOT</version>
        </dependency>
    </dependencies>
</project>

I even copied the ´dependency´-block and the ´repository´ block directly from jitpack.io's website.

In my ´settings.xml´ I only have the access token to my maven repo. Anything else I need to put in there maybe?

Thank you for taking your time to read my question.

The problem is probably with the WolfyScript/CustomCrafting GitHub repository, as the maven project inside can't be build by default.

Jitpack runs mvn install -DskipTests by default

There are at least two problems with the project:

1. it is using maven-shade-plugin 3.3.0-SNAPSHOT that is not available in maven central repository
2. it has a dependency on other wolfyscript artifact, that is not present in the same repository / maven project and it (probably) should download it from the defined private repository that requires authentication:

authentication failed for https://maven.wolfyscript.com/repository/private/com/wolfyscript/wolfyutilities/wolfyutilities/3.16.3.2/wolfyutilities-3.16.3.2.pom, status: 401 Unauthorized

That project is located here: https://github.com/WolfyScript/WolfyUtilities

To be able to use that repository with jitpack, its author should fix the mentioned problems and/or configure jitpack to be able to build the project
