Fixed version (ground truth):

    if (!project.hasAllFacets(deps)) {
      List<String> facetNames=new ArrayList<String>();
      for (      Class<? extends Facet> f : deps) {
        facetNames.add(ConstraintInspector.getName(f));
      }
      if (shell.promptBoolean("String_Node_Str" + facetName + "String_Node_Str"+ facetNames+ "String_Node_Str")) {
        projectFactory.installSingleFacet(project,facet.getClass());
      }
 else {
        abort();
        return;
      }
    }
    if (!facet.isInstalled() || !project.hasFacet(facet.getClass())) {
      project.installFacet(facet);
    }
    if (!updatePackaging(facet)) {
      abort();
      return;
    }
    if (facet.isInstalled()) {

    }
