Is the .jar supposed to be built by the mvn compile command above? Because currently it isn't (the directory target/ is there, but it doesn't contain the .jar). So either the build should be fixed, or an explanation linking the previous section with this one is needed.

Alternative version (meant to highlight that there is nothing to be done by default to just run tests):

Unit tests rely on test data that are already available in the Git repository (under src/test/dataset/), so you generally only need to run them using Maven, as shown above. In case you want to regenerated the test data, you can do as as follows:

... or something along these lines.

as per above, this doesn't work as the .jar is not available under target/

I forgot the assembly:single part here, it is indeed a mistake. However the default name of generated .jar file is swh-graph-1.0-jar-with-dependencies.jar and I was trying to search for ways to rename it to simply swh-graph-1.0.jar but solutions are not great and this is default behavior in maven so I will update the naming too.
