如何在Eclipse 3.7中安装Aptana插件？

Question

我试图在Ubuntu的Aptana Studio的插件3安装到Eclipse 3.7，但它与消息

An error occurred while collecting items to be installed 
session context was:(profile=PlatformProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=). 
No repository found containing: osgi.bundle,org.eclipse.jdt.core,3.7.0.dist 
No repository found containing: osgi.bundle,org.eclipse.jdt.core.manipulation,1.4.0.dist

No repository found containing: osgi.bundle,org.junit,3.8.2.v3_8_2_v20100427-1100 

我使用的包网址为http://download.aptana.com/studio3/plugin/install失败。我究竟做错了什么？

更新：我也跟着下面sgibly的意见，现在安装获得约49％与此消息失败之前：

An error occurred while collecting items to be installed

试试这个：

打开Eclipse的首选项，并查找安装/更新 - >可用软件并确保已选中Indigo更新站点。

如果未选中，请添加http://download.eclipse.org/eclipse/updates/3.7并尝试再次安装Studio。

希望有所帮助。
