Eclipse source out of sync with file system

I inherited a java project and don't have much experience with Eclipse. 开发者_StackOverflow社区In the package explorer I can see the outline of the project with all the classes but when I try to edit any of them it says the source code is not found. When I look the source code is where it seems it is supposed to be. I am assuming that in pulling the code out of source control the path must have changed from the original. Is there an easy way to tell the IDE to just connect a code file to a class?

What's really weird is that 'some' of the files in the very same directory are found while others are not. Can't say I think very highly of this IDE so far.

Right click on the project in the Package Explorer view and select Refresh.

You can have Eclipse do that automatically for you.

Using the latest version, go to Window -> Preferences.

Select General -> Workspace and from there make sure the first and second option are checked:

• Build automatically
• Refresh using native hooks or polling

This is very useful especially if you use Dropbox or something similar (wuala etc) :)

just refreshing isnt always the answer. I had this source issue happen when I had imported two projects with the same context for review and Eclipse made me disambiguate them, forcing a change to the web context of the second. The source for one was linking to the other context's source folder. eg

• project A(in folder A1) deployed as /A
• project A(in folder A2) deployed as /A also but was forced to be /A[later**] upon import

in .settings/org.eclipse.wst.common.component (within folder A1) the wb-module element referred to the other context /A[later] and was using its source code, not that for /A.

I solved this by updating all references in the org.eclipse.wst.common.component file in each project to suit their correct project

** the suffix I chose upon import, it has no particular significance

By default, 'F5' on a highlighted resource will also refresh it.

You can right click on the project name and click refresh. And just to be sure, you can select the package name and right click 'Refresh' too.

1. Right click on the project in the Package Explorer view and select Refresh. If it is not working,
2. Clean the project... project menu -> clean... and refresh

Click on the project, then press F5 to refresh the file. It should be fine.

If refresh and clean doesn't work, it might work to just simply just run your code. For me it did the trick. After many refresh and cleaning/ building didn't work.

Just remove all projects from eclipse workspace and Re-Import the all projects again. It is working for me. Just try it

If using maven or other builder be sure that you disable the plug ins some plug ins, specially the ones meant to generate/change code will never let you be fully on sync
