如果你的windows电脑，你可以试试这个，它也是STS:

Ctrl + win + Alt + Down::将当前行或所选行复制到下方

Ctrl + win + Alt +向上::将当前行或所选行复制到上方

如果你想复制一行到剪贴板，你也可以使用这个技巧:

Ctrl-Alt-Down 紧随其后的是 Ctrl-X

缺点是复制该行的文件变脏了。

对于个人使用，我添加了一个vim插件，如Vrapper到Eclipse，只使用yy复制整行。

You have to turn off the graphics hot keys that flip the screen. If you're on Windows, you need to right click on the Windows desktop and select "Graphics Properties..." (or something similar depending on your version of Windows). This will bring up a screen where you can manage graphics and display options, look for a place where you can disable hot keys, sometimes it's hidden under something like "Options and Support". Turn off the CTRL + ALT + ↑ and CTRL + ALT + ↓ hotkeys (alternatively you can just disable all graphics hot keys if you're not using them).

在MAC中试试这个。

alt+命令+下

它的工作原理。

Ctrl +alt+下/上/左/右作为热键优先于eclipse设置。作为替代，我尝试了不同的方法。

Step 1: Triple click the line you want to copy & press `Ctrl`-`C`(This will
select & copy that entire line along with the `new line`).
Step 2: Put your cursor at the starting of the line where you want to to paste
your copied line & press `Ctrl`-`V`.(This will paste that entire line & will
push previous existing line to the new line, which we wanted in the first place).
