Poste a definição do plugin que você usou pra rodar e o código. Rodando localmente não vai dar certo mesmo, precisa ser em um plugin do Eclipse (e o plugin deve declarar dependência do plugin “resources”).
No plugin está assim:
E a classe que inicia o plugin:
Mas o problema é mesmo na minha classe,pq se eu altero o plugin pra dar um simples Hello world ele funciona, portant ocreio que o problema esteja na minha classe.

Alguma ideia, Ataxexe?
No GUJ não tem muito conteúdo sobre plugins e em todo material em que eu encontrei,o código pra pegar projetos do eclipse é igual esse meu:public void getProjects(){
IProject[] projects = ResourcesPlugin.getWorkspace().getRoot().getProjects();
int i;
for(i=0;i<projects.length;i++){
System.out.println("Projeto: "+projects[i]);
}
}
Pelo que me parece,está faltando é algum pacote.Eu usei somente esses imports:
import org.eclipse.core.resources.IProject;
import org.eclipse.core.resources.ResourcesPlugin;>
