build.xml is a an ant file. To execute it, type:

1.BASIC BUILD
ant

int the directory with this file. 
The sources should be (jmetal and greenmetal directories) in the directory ../src
It will create a running jar archive in directory ../Experiment
Classes used to create jar are in ../bin. This directory is cleaned every time ant is run.

After that you can execute experiments using command: java -jar EME.jar [name of target dir].
Target dir should include the instances on which you want to run the algorithm: dag file and processors file.
The dag file should finish with .dag extension and should NOT include char '_' in the name, as name of the instance is directly used in latex output files. The default processors file is file_proc.

2. CLEAN
ant clean to delete dir  ../bin.


ALTERNATIVES:
A. Algorithms can be directly by running proper *_main_EMscheduling class from greenmetal.metaheuristics package.
B. In a development environment such as Eclipse, you can link greenMetal sources to project with jMetal and directly work in the environment.
