Adding a directory path under IntelliJ 12 claims Library 'LibraryName' is not used and has no effect

Hello,

it is not enough to create a project library, you also need to add it to the dependencies list of a module ('Dependencies' tab of the module editor).

Thanks. Please forgive my ignorance here but where is the module editor?
Is it possible our plugin inadvertantly disabled it?

This is my module settings UI

FYI some additional info, I got some help on StackOverflow and it seems our plugin doesn't handle the modules section correctly. This isn't necessarily bad since we don't want developers changing the classpath, but I want to be able to define the dependencies correctly for the project I generate. How do I do that?

Thanks.

'Dependencies' tab is shown only for Java modules by default, it won't be shown if your module has a custom ModuleType.

To add a dependency to a module via API use ModuleRootManager class:

ModifiableRootModel model = ModuleRootManager.getInstance(module).getModifiableModel();
model.addLibraryEntry(library);
model.commit();

OK I just tried this is the code I have for project creation, I ran in the debugger and it seems this code is executing properly but the result is exactly the same as above:
    @Override
    void createProjectFolders(VirtualFile rootPath) throws IOException {
        super.createProjectFolders(rootPath);
        final VirtualFile libImplClasses = ProjectPaths.findOrCreateChildDirectory(rootPath, "lib/impl/cls");
        final VirtualFile libImplStubs = ProjectPaths.findOrCreateChildDirectory(rootPath, "lib/impl/stubs");
        new WriteAction<Library>() {
            protected void run(final Result<Library> result) throws IOException {
                final LibraryTable libraryTable = LibraryTablesRegistrar.getInstance().getLibraryTable(getProject());
                String libName = "library.cn1lib.name";
                Library library = libraryTable.getLibraryByName(MessageBundle.message(libName));
                if (library == null) {
                    library = libraryTable.createLibrary(libName);
                    final Library.ModifiableModel model = library.getModifiableModel();
                    model.addRoot(libImplClasses, OrderRootType.CLASSES);
                    model.addRoot(libImplStubs, OrderRootType.SOURCES);
                    model.commit();
                    ModifiableRootModel rmodel = com.intellij.openapi.roots.ModuleRootManager.getInstance(getModule()).getModifiableModel();
                    rmodel.addLibraryEntry(library);
                    rmodel.commit();
                }
                result.setResult(library);
            }
        }.execute();
    }
