Sorry, I have difficulties to setup up development environment in Eclipse.

I am pretty new to Eclipse Environment.
I followed the instruction
Build using Maven from project root:

(in "eclipse-instasearch" folder)
mvn install

Use File -> Import -> Existing Projects to import all instasearch projects ("eclipse-instasearch" folder)
To run or debug right click on 'instasearch' project and select Run As -> Eclipse Application

in "MANIFEST.MF" it complains "Bundle 'org.apache.lucene' cannot be resolved"

Run As Eclipse Application will show this exception in the Console :

org.osgi.framework.BundleException: Could not resolve module: it.unibz.instasearch [19]
  Unresolved requirement: Require-Bundle: org.apache.lucene; bundle-version="[2.9.1,2.9.2]"

log4j:WARN No appenders could be found for logger (org.eclipse.jgit.internal.storage.file.FileSnapshot).
log4j:WARN Please initialize the log4j system properly.

I also tried "Open Project From FileSystem" to open the root folder, in this way there is no option "Run As Eclipse Application" in the context menu.
