Why importing fuse quickStarts expose maven compilation errors in JBDS ?

Issue

• When inmporting the FUSE-QS (fuse quickstarts) into DevStudio(8.1.0). The Studio complains with the following error/warning:

Description Resource    Path    Location    Type

• I can run mvn clean install from shell and inside Developers Studio using "run as", but still these warning exists. I did "maven->update all projects", but i still have the errors. Is there any changes needed in the maven "settings.xml".
