Clay markII 收费了，取消了直接下载的链接。我之前有用它开发，现在先不到了。用1.4.0的版本打不开。所有只好用在线安装的方法。具体如下：
安装方法：
- From the Eclipse menu, select Help > Software Updates > Update Manager. This will cause Eclipse to switch to the Install/Update Perspective.
- In the Feature Update view in the lower left, right-click to bring up the popup menu, and select New > Site Bookmark. This will start the New Site Bookmark wizard.
- Enter the following information:
- In the name text field, type
Azzurri Plugins - In the URL text field, type
http://www.azzurri.jp/eclipse/plugins - Make sure the Eclipse Update Site radio button is selected, and press OK
- In the name text field, type
- The Feature Update view in the lower left will now have the Azzurri Plugins site folder you just created. Expand the site folder to browse the features available for download.
