解决安装Egit时Egit Mylyn和org.eclipse.team.core报错

为了让Aptana支持GitHub，需要安装Egit，但在的时候碰到两个错误,一个是关于缺少EGit Mylyn另一个是缺少org.eclipse.egit.import.feature.group。

 

缺少Egit Mylyn的提示：

Cannot complete the install because one or more required items could not be found.
  Software being installed: EGit Mylyn 1.1.0.201109151100-r (org.eclipse.egit.mylyn.feature.group 1.1.0.201109151100-r)
  Missing requirement: EGit Mylyn 1.1.0.201109151100-r (org.eclipse.egit.mylyn.feature.group 1.1.0.201109151100-r) requires 'org.eclipse.mylyn.team_feature.feature.group 3.5.0' but it could not be found.

缺少org.eclipse.egit.import.feature.group的提示：

To: org.eclipse.egit.ui [3.0.1.201307141637-r]

解决这两个问题，很简单：
只要取消EGit Mylyn和EGit Import Support这两个功能能就可以了。因为这两个功能都是可选的。不会影响使用GitHub。
