[FIXED] Why a module in my multi-module maven project doesn't work?

Issue

I fetched a project from a remote repo. As a result, I have a project with 3 modules that work fine and one module that somehow is not a part of the project or something. Here is the screenshot of my project:

So anagram, calculator and char counter work well, but java-8-api does not.

Here is the root pom.xml:

<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://maven.apache.org/POM/4.0.0"

Here is the java-8-api pom.xml:

            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

Any help appreciated.
