dataflow-shaded is a dataflow framework based on the javac compiler. It differs from the org.checkerframework:dataflow artifact in two ways. First, the packages in this artifact have been renamed to org.checkerframework.shaded.*. Second, unlike the dataflow artifact, this artifact contains the dependencies it requires.

There is a newer version: 3.42.0-eisop5
