解決安裝Egit時Egit Mylyn和org.eclipse.team.core報錯

為了讓Aptana支持GitHub，需要安裝Egit，但在的時候碰到兩個錯誤,一個是關於缺少EGit Mylyn另一個是缺少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：

解決這兩個問題，很簡單：
只要取消EGit Mylyn和EGit Import Support這兩個功能能就可以了。因為這兩個功能都是可選的。不會影響使用GitHub。
