Eclipse “Import cannot be resolved” error

by Sherif

I’m amazed at how many shortcuts or different ways there are of doing things in Eclipse.

Recently I kept hitting an issue of Eclipse not recognising my imports (even though they were there). I was always getting the message:

import ClassName cannot be resolved.

Where ClassName was my imported class. I’m using the MyEclipse Workbench 5.5.1 on Eclipse 3.2. Here are a few tips on how you can fix this (some worked for me, some didn’t):

‘Clean’ Your Eclipse Project: Go to Project > Clean in Eclipse [This seems to work for me]
Refresh your project folder (right click on your project > refresh)
Re-build your project
Clean your builds (If using Ant or Maven – clean your builds)
Recreate your project in Eclipse
‘Switch’ Workspace – then Switch back (Eg Change to Debug, then switch back to Java)
‘Switch’ Workspace – then Switch back (Eg Change to Debug, then switch back to Java)
Remove and re-add your JRE:
1. Right Click on your project > properties
2. Click on the Libraries tab
3. Click on the JRE
4. Click remove, then OK
5. Repeat 1-3 again, but add the JRE again

Hope at least ONE of those tips help!

今天遇到的问题，包明明存在却突然报找不到包的错误，重启eclipse无法解决，Refresh也不行。最后是通过Project-Clean解决掉的。上面是一篇文章，列举了一系列的方法。
