如何向eclipse添加maven插件

我是马文的新手。我试图将maven插件添加到eclipse（indigo）。我面临的问题是，当我尝试使用URL“帮助->安装新软件”添加插件时，下载过程开始，然后停止，并出现错误

An error occurred while collecting items to be installed

另外，当我尝试使用安装插件时，安装被卡住了48%，很长一段时间后，它再次显示一条错误消息：

如果我使用的安装过程有问题，请提出建议

还建议是否有其他方法添加“maven插件for eclipse”

谢谢

检查在安装过程中联系所有更新站点，以便在安装m2e之前找到所需的软件选项
