Fixed version (ground truth):
public boolean execute(){
  try {
    IProject rootProject=DQStructureManager.getInstance().createNewProject(org.talend.dataquality.PluginConstant.getRootProjectName());
    rootProject.delete(true,true,new NullProgressMonitor());
    rootProject=DQStructureManager.getInstance().createNewProject(org.talend.dataquality.PluginConstant.getRootProjectName());
    IResource[] resources=ResourcesPlugin.getWorkspace().getRoot().members();
    if (resources != null && resources.length > 0) {
      for (      IResource resource : resources) {
        if (resource instanceof IProject && !resource.getName().equals(org.talend.dataquality.PluginConstant.getRootProjectName())) {
          IPath destination=null;
          IFolder prefixFolder=rootProject.getFolder(DQStructureManager.PREFIX_TDQ + resource.getName());
          prefixFolder.create(IResource.FORCE,true,new NullProgressMonitor());
          for (          IResource rs : ((IProject)resource).members()) {
            if (rs.getName().equals("String_Node_Str")) {
              continue;
            }
            destination=prefixFolder.getFolder(rs.getName()).getFullPath();
            rs.copy(destination,IResource.FORCE,new NullProgressMonitor());
          }
          resource.delete(true,new NullProgressMonitor());
        }
