問題：
Eclipse does not highlight matching variables for me: Eclipse 沒有爲我突出顯示匹配的變量：
I've already tried to change "Mark occurrences" via我已經嘗試通過更改“標記出現次數”
Window -> Preferences -> Java -> Editor -> Mark Occurrences
but it didn't work.但它沒有用。 I am not sure why this is not working while others have been able to fix the problem.我不確定爲什麼這不起作用，而其他人已經能夠解決問題。
Can anyone tell me how can I set highlighting matching variables?誰能告訴我如何設置突出顯示匹配變量？
Looking for same variables with my eyes really bothering me too much.用我的眼睛尋找相同的變量真的讓我太煩惱了。
