步骤5：加入lib包：
切换到Libaries选项卡，“Add Library"->"IvyDE Managed Dependencies"->"Next",选择“Project”，选择ivy\ivy.xml文件。点 Ok。eclipse会自动下载依赖的jar包。
在这个过程中或许会报错，看到错误信息是因为org.restlet.jse包下载不到。解决方法是：ivy\ivy.xml中找到
<dependency org="org.restlet.jse" rev="2.0.5" conf="*->default" />
<dependency org="org.restlet.jse" rev="2.0.5"
conf="*->default" />
部分，注释掉。在网上手动找到这两个包，放在lib包下，加入到Libaries中。
接着加入plugin文件夹下各个插件的ivy.xml文件。手动一个一个加进去。
步骤6：在"Order and Export"选项卡，将 conf top
