Eclipse project imported - class reference missing

Hi,
I'm working on a small clojure project from a previous developer and running into an error around class and Leiningen references. I think this is some type of noob issue, since I have never imported projects before and I have only built Birt reports in Eclipse.

Installed Environment:
Eclipse Neon.2 (4.6.2)
Leiningen
Counterclockwise (google clojure)
Oracle Database tools(from Eclipse Marketplace)
running on win 7 74 bit vm.

Imported by:
- Eclipse: File> Open Project from File System


Errors:
1. Classpath error on class. - (missing)
2. Leiningen Managed Dependencies issue: problem resolving following dependencies: [oracle.jdbc/oracledriver "12.1.0.2.0"

Any help is appreciated!!!

What I have tried:

1. Tried for class native path .../target/base+system+user+dev/native/windows/x86_64
2. Installed Oracle DB Tools and Leiningen
3. right click on project>Leiningen>"Reset project configuration"
