安装ADT-Plugin失败

Question

我目前正尝试为Eclipse安装ADT-plugin（Eclipse Helios / CentOS 6.5）。指定下载URL

后

https://dl-ssl.google.com/android/eclipse/

我可以选择要安装的软件包。然后下一步失败并显示以下错误消息：

Cannot complete the install because one or more required items could not be found.
  Software being installed: Android DDMS 22.3.0.v201310242005-887826 (com.android.ide.eclipse.ddms.feature.group 22.3.0.v201310242005-887826)
  Missing requirement: Android DDMS 22.3.0.v201310242005-887826 (com.android.ide.eclipse.ddms.feature.group 22.3.0.v201310242005-887826) requires 'org.eclipse.ui 3.6.2' but it could not be found

任何想法如何解决这个问题？ Android-SDK当然已安装......

谢谢！
