1. 直接安装color theme
eclipse：Help->Install New Software->Work with:Update Site -http://eclipse-color-theme.github.com/update
2.安装 Eclipse Marketplace
help--install new software--add
添加name: Eclipse Marketplace Client (随意起名)
Location:http://download.eclipse.org/mpc/indigo/
把"Contact all update sites during install to find required software"前面的勾去掉，然后点击下一步，这样之后问题迎刃而解了。
2安装 Eclipse Color Theme
打开Eclipse选择help - Eclipse Marketplace
然后在search窗口输入: Eclipse Color Theme 然后点 Go
