Corpus-CC

This library is built using Spring Boot microservices for detecting types 1-3 code-clones in Java applications.

MongoDB Prerequisites

Before installing this project you'll want to make sure you have a MongoDB instance running. Configuration of the instance and user can be done for the cc-detection and cc-pipeline microservices.

Architecture

The architecture for the application is divided into four main microservices -

• cc-detection : This microservice is in charge of finding clones between the corpus and the application
• cc-discovery : This microservice is in charge of finding the local source files in an application
• cc-pipeline : This microservice is in charge of loading a corpus from a source application
• cc-tokenizer : This microservice is in charge of tokenizing source files and running heuristics

Loading the Corpus

To load the corpus you will want to send a discovery request to the "/findClones" endpoint for a full list of clones or the "/findRankedClones" for a breakdown of the clones by severity.

The discovery request is structured as follows -

{
  "baseFolder" : "<path-to-application>",
  "depth" : 15,
  "basePackage" : ""
}

Built With

• Spring Boot - Open-source Java-based framework used to create a microservices
• Javaparser - Lightweight set of tools to generate, analyze, and process Java code
• Gson - Java library that can be used to convert Java Objects into their JSON representation
