Deblometer

A Java Debloating Benchmark

Deblometer consists of two main components:

1. Analysis (in the Analysis folder)
   This contains the logic of the Deblometer analysis.
   It requires:

   • The compiled ground truth code
   • The JSON ground truth files corresponding to the tested language features

   Both the compiled ground truth JARs and the JSON files are already included in the resource folder (undebloated Jars) inside the Analysis directory and can be directly used for testing.

2. Groundtruth (in the DeblometerGroundtruth folder)
   This contains the language feature modules that define the ground truth.
   Each module provides:

   • The source code of the feature under test
   • The JSON file with the expected outcome

   The undebloated JARs used in the analysis can be generated by compiling these modules.

This setup allows you to evaluate the precision and soundness of the debloating tool of your choice with the Deblometer analysis.

Installation Process

The installation process consists of four steps:

1. Compile the Ground Truth language feature modules
   In each module inside the DeblometerGroundtruth folder, run:

   mvn compile package

2. debloat the produced JARs using the debloating tool of your choice.
3. In the Analysis resources folder, create a folder for the debloated JARs (e.g., Analysis/src/main/resources/debloated-jars/), copy the debloated JARs there, and update the path variable debloatedJarsFolder inside Deblometer.java to point to this folder.
4. Run the project
