This repository hosts the SootDiff analysis tool. SootDiff allows the comparison of the Java ByteCode create by different Java compilers. To do so it uses static analysis and optimizations to unify the generated ByteCode, e.g. Constant Propagation, Dead Code Elimination, String Handling. Its goal is to provide researchers and practitioners with a tool and library on which they can base their own research projects and product implementations.

You can either build SootDiff on your own using Maven, or you can download a release from here on Github.

The Release Page contains all pre-built JAR files for each release that we officially publish. We recommend using the latest and greatest version unless you have a specific issue that prevents you from doing so. In that case, please let us know.

To build SootDiff with Maven run

mvn install

or to build a standalone jar-with-dependencies run

mvn clean compile assembly:single

If you want to read the details on how SootDiff works, the published paper SootDiff @SOAP'19,Phoenix, AZ, USA is a good place to start.

SootDiff is licensed under the MIT license, see LICENSE file. This basically means that you are free to use the tool (even in commercial, closed-source projects).
