------------------------------------------

Can you provide a live example for such feature?

Parallel build graph is built according to dependencies between modules in your project.

So correct dependencies should cover your requirements.

> It would be great if one can specify in the pom if a project is safe to execute in parallel.
> I sometimes have a multi-module project where most of the module can run easily in parallel but some needs serial execution, currently using some "hacks" to enforce this.
> This should work the following way:
> # If all projects are marked as "parallel" all works like today (default)
> # If a project is marked as not run in parallel, first execute all projects in the build order until this project
> # Then execute the serial one and proceed with the same (that is execute all in parallel until the next serial project is found)
> This could happen on different level, e.g. such a strategy might be delegated to the builder, or the code that calling the builder can "slice" the projects in the given way and call the builder multiple times.
> Nerveless this will require some change to the project-model to mark a project as parallel, or one might be able to use a project-session-property or alike.
