after referring some questions in stack and in google, i got something like this hope these may help you
as you have done before just remove all your dependencies and add build path and clean project once if it dint work just go through the things
The easiest way to deal with such a library in Eclipse is to create a User library and add the user library to your project (right click project: Build Path -> Add Library -> User Library).
Here is a short guide to generating a User Library:
Open the menu entry Preferences -> Java -> Build Path -> User Libraries
Press New..., enter a name (e.g. 'Guava')
Press Add JARs... and search for the JAR files you downloaded
(Unzip the Guava archive beforehand, inside you'll find the file guava-r07.jar. Select that in this dialog, preferably after moving it to a more desirable location)
Now select Source Attachment -> Edit..., and find the path to the file guava-src-r07.
If you want to, you can repeat this process for the JavaDoc location, pointing it to the javadoc folder from the guava distribution
Press OK.
and some other suggestions are like
use Maven to import the libraries. It makes it simple to upgrade dependencies later and, once you install m2eclipse, Eclipse will pick the Guava libraries up for you. All you need in your Maven pom.xml to "use Guava" is something along the lines of the following in your dependencies section.
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>15.0</version>
</dependency>
