GitCE is a groovy project that uses Gremlin Graph Traversal language to query a Neo4j database which contains metadata about project repositories hosted at GitHub. It takes as input the directory path to the graph database and outputs a list of all the merge commits that happened in the database history. Each item of this list contains the merge commit SHA-1 and their parents SHA-1. The output list is structured in the following manner:
MergeCommit1, Parent1, Parent2
...
MergeCommitN, Parent1, Parent2
Currently, the project saves the output list in a .csv file. To run this project, you need the following instructions:
1- Clone and run Gitminer (https://github.com/pridkett/gitminer), according with their instructions to download the database containing the desired projects metadata.
2- Once you have the graph.db folder in your computer, clone or download the GitCE project
3- Run 'mvn eclipse:clean' to download the project's dependencies.
4- Import the project into eclipse using "Import > Maven > Existing project into workspace..."
5- In projects.csv put details about projects that you want to analyse.
6- Run App.groovy, you may chose between some running options in this file. A .csv file will be created in the directory where you cloned the GitCE project.
