Answer 1

You need to import it as a Java/Maven project. Once you are done importing the project do the following steps

Go to Project -> Select Properties -> Select Project References -> Select/Check all the dependent/Child projects which you reference in the code base -> Apply and Close

Once you are done, try to clean the whole project. This should solve the issue.

Answer 2

You needed to to check it out as a Java Project, or preferably, its creator should have committed the .project and .classpath files for it.
