integrate an ant project - eclipse

Question

I want to run a following project:
https://gforge.inria.fr/plugins/mediawiki/wiki/melinda/index.php/RDF_keys
In the project page, they resume the steps as the following:
1-git clone https://gforge.inria.fr/git/melinda/melinda.git
2-cd melinda/trunk/rdfifd/
3-ant jar
4- java -jar pseudo-keys.jar -t -i /path/to/rdf_file -o /path/to/output/file
So how can i integrate and run this project in an eclipse project?
I already following these setp on a linux command line and it is work well and pseudo-keys.jar is generated. I take this .jar and In my laptop i write the following code:
public class TestDriver {
/** Executes a command */
public static void execute(String cmd, File folder) throws Exception {
Process p = Runtime.getRuntime().exec(cmd, null, folder);
BufferedReader bri = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader bre = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String s1, s2 = null;
while (null != (s1 = bri.readLine()) || null != (s2 = bre.readLine())) {
if (s1 != null) System.out.println(s1);
if (s2 != null) System.err.println(s2);
}
p.waitFor();
}
public static void main(String[]args) throws Exception{
String cmd = "java -jar C:/Users/user/Desktop/pseudo-keys.jar -t -i C:/Users/user/Desktop/randomLocation/datasetLocation/restaurant1.rdf -o C:/Users/user/Desktop/randomLocation/key.xml";
execute(cmd, null);
}
The execution give the following error:
java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException

Any help please to run the code? Where is my mistake?

Copy the URI https://gforge.inria.fr/git/melinda/melinda.git to the clipboard
In the Git Repositories click the Clone a Git Repository button and follow the wizard (if the dialog is not prefilled, enter the URI manually)
Right-click the node melinda [master] > Working Tree > trunk > rdfifd and choose Import Projects... and follow the import wizard
In the Package Explorer or Project Explorer open the file rdfifd/build.xml via double-click
In the Outline view right-click the target jar and choose Run As > Ant Build
On the command line run java -jar pseudo-keys.jar -t -i /path/to/rdf_file -o /path/to/output/file. Alternatively, you can skip step 4 and 5 and run fr.inrialpes.exmo.rdfkeys.KeyExtraction as Java application with the necessary arguments (Run > Run Configurations..., in tab Arguments field Program arguments).
