Find the building tool and add dependency

Theodosios,

You can access all project's modules with:

ModuleManager.getInstance(project).getModules()

Adding dependencies programmatically is not supported out of the box. You'll have to work with Psi model at this point.

Jakub Chrzanowski thanks for the answer but this returns me the .iml files. 

How i can find from there the build.gradle or the pom.xml to add a debendency?

You can loop through the returned modules and check their types i.e. with:

MavenUtil.isMavenModule(module)

or:

FacetManager.getInstance(module).getFacetByType(FacetTypeId);
