rcp（插件开发）屏蔽eclipse的菜单项

一般我们可以在插件启动的时候做一下判断，来去除我们不要的菜单项

具体代码如下：

WorkbenchWindow window = (WorkbenchWindow)PlatformUI.getWorkbench().getActiveWorkbenchWindow();

PerspectiveBarManager barManager = window.getPerspectiveBar();

CoolBarManager manager = window.getCoolBarManager();

//manager.removeAll();

MenuManager manager2 = window.getMenuBarManager();

//manager2.removeAll();

IContributionItem[] contributionItems = manager2.getItems();

for(IContributionItem item : contributionItems) {

System.out.println(item.getId());

}

manager2.remove("help");

manager.update(true);

manager2.update(true);
