In order to run the conflicts analyzer you will need to have Java 7 or higher, groovy, maven and R installed in your machine. After that, you will need to clone the required projects from github and import then inside Eclipse IDE according to the instructions described below:

1- clone and build gitminer

git clone https://github.com/prga/gitminer.git
cd gitminer
mvn clean compile package assembly:single
cd ..

2- clone GremlinQuery and switch to right branch

git clone https://github.com/prga/GremlinQuery.git

3-clone featurehouse (ssmerge)

git clone https://github.com/prga/featurehouse.git

4- clone conflictsanalyzer

git clone https://github.com/prga/conflictsAnalyzer.git

After cloning these 4 projects (gitminer, GremlinQuery, featurehouse, and conflictsAnalyzer), you need to import 3 projects inside Eclipse IDE

5-Open Eclipse

6- Import project GremlinQuery

import ->maven->existing maven projects select GremlinQuery folder and click open and then finish install required plugins restart eclipse

6.1 - if you have problems with groovy compiler mismatch do this

right click on project’s folder -> groovy-> fix compiler mismatch problems

right click on project’s folder -> maven -> update project

7- import featurehouse

import->general-> existing projects into workspace

select featurehouse folder click open, check that all 4 projects are selected (CIDE_generateAST, CIDE2_ast, fstcomp, fstgen, fstmerge), and click finish

8-import conflictsAnalyzer

import-> existing projects into workspace

select conflictsAnalyzer folder, click open and then finish

9- Edit properties files and run conflictsAnalyzer project

Edit projectList file with the list of projects you wish to analyze, following the file pattern with one project per line

Edit configuration.properties file with the following information:

-gitminer.path, should be set to the path of gitminer project

-downloads.path, should be set to the path where you want to download projects revisions

-github.login, your github login

-github.password, your github password
