New Views Don’t Show Up When Using Eclipse RCP setSaveAndRestore

rcp程序创建view时不显示的问题：

public class Perspective implements IPerspectiveFactory {

 public void createInitialLayout(IPageLayout layout) {

  //System.out.println("hahahahahah================");

  String editorArea = layout.getEditorArea();

        layout.addView("com.adtec.demo.views.FirstView", IPageLayout.RIGHT, 0.2f, editorArea);

 }

}

方法并没有执行，解决方案如下，勾选clear，重新运行即可：

run as->run configrations..->main->clear勾选上
