Looking for PostDoc or Ph.D. student to work on Soot!

The research group of Eric Bodden has acquired funding for a three-year project that will fund a PostDoc or Ph.D. student with the goal of applying major upgrades to Soot to make it sustainable for the future. The position is fully funded and does not include any teaching or administrative duties (although teaching is possible if desired). We will assure that at least 50% of the time can also be spent on personal research.

As Soot is one of the most widely used research infrastructures worldwide, this position will give you a great opportunity to obtain wide exposition in the research community. In case you are interested in applying, please contact Eric Bodden directly.

Soot supports Java 9 modules now!

Try and get involved in Soot's Java 9 bleeding edge developement. Check out the Soot-j9 branch.

What is Soot?

Soot is a Java optimization framework. It provides four intermediate representations for analyzing and transforming Java bytecode:

  • Baf: a streamlined representation of bytecode which is simple to manipulate.
  • Jimple: a typed 3-address intermediate representation suitable for optimization.
  • Shimple: an SSA variation of Jimple.
  • Grimp: an aggregated version of Jimple suitable for decompilation and code inspection.

See for details.

How do I get started with Soot?

We have some documentation on Soot in the wiki and also a large range of tutorials on Soot.

Including Soot in your Project

A Soot snapshot release is currently built for each commit to the develop branch. You can include Soot as a dependency via Maven, Gradle, SBT, etc using the following coordinates:

    <name>soot snapshots</name>

Please make sure that your Java version is up to date to avoid problems with our SSL certificate

You can also obtain older builds of the develop branch. A complete listing of builds can be found in our Nexus repository.

How do I obtain Soot without Maven?

All of our Soot builds for the develop branch are stored up to one month in our Nexus repository and can be obtained from there. The latest snapshot build of Soot can also be obtained directly. The "sootclasses-trunk-jar-with-dependencies.jar" file is an all-in-one file that also contains all the required libraries. The "sootclasses-trunk.jar" file contains only Soot, allowing you to manually pick dependencies as you need them. If you do not want to bother with dependencies, we recommend using the former.

Building Soot yourself

If you cannot work with the prebuild versions and need to build Soot on your own, please consider the wiki for further steps.
