Just click Window->Reset Perspective and everything will be back as it was when you installed eclipse. Sure you'll have to customize it back to how you like it, but at least you'll have the console back. 回答2: If

How can I add the Marketplace Client to the classic Juno bundle? 回答1: As far as I know, the Classic distribution does not contain the Marketplace client (and that is the only such official distribution).

What is the main reason for upgrading to Eclipse Juno? [closed]

阅读更多关于 What is the main reason for upgrading to Eclipse Juno? [closed]

Sorry if this is a strange question. But I've been using Indigo for a long time, and after upgrading to Juno I find that the UI is less responsive, has bizarre new colors (thankfully they included a Classic theme) and not a single new feature that I can see, anyway. They changed the default redo shortcut from ctrl-y to ctrl-shift-z, even though ctrl-y is a de-facto standard for that type of shortcut. Seems like a lot of changes for change's sake. Frankly I am somewhat underwhelmed by this release. I'm not deliberately trying to be negative here, I guess I just haven't seen the light yet :-)
