已经安装了集成java版本的eclipse，eclipse-java-indigo-SR1-win32.zip，在添加CDT插件时，遇到了问题。
cdt-master-8.0.1.zip http://www.eclipse.org/cdt/
通过help->install new software安装，提示以下错误：
Cannot complete the install because one or more required items could not be found.
Software being installed: C/C++ Remote Launch 6.0.0.201109151620 (org.eclipse.cdt.launch.remote.feature.group 6.0.0.201109151620)
Missing requirement: C/C++ Remote Debug Launcher 2.3.0.201109151620 (org.eclipse.cdt.launch.remote 2.3.0.201109151620) requires 'bundle org.eclipse.rse.ui [3.0.0,4.0.0)' but it could not be found
Cannot satisfy dependency:
From: C/C++ Remote Launch 6.0.0.201109151620 (org.eclipse.cdt.launch.remote.feature.group 6.0.0.201109151620)
To: org.eclipse.cdt.launch.remote [2.3.0.201109151620]
从上面的错误信息可以看出，缺少了org.eclipse.rse.ui
在eclipse上可以找到各版本eclipse的区别：http://www.eclipse.org/downloads/compare.php
对比可以发现，集成了CDT的eclipse多了一个RSE组件，所以单独下载RSE组件：
RSE-runtime-3.3.1.zip http://www.eclipse.org/tm/
通过help->install new software方式安装RSE时出错了，不管它，直接解压复制到eclipse相应目录下即可
再次安装CDT，成功了
