How to clear cache of Eclipse Indigo

Question

I would like to know what is the standard way to clear the cache of Eclipse Indigo?

Answer 1

I think you can find the answer you want in these two posts. They are mentioning Flash Builder, but essentially, the talk is about its Eclipse base.

Answer 2

If you are asking about cache where eclipse stores your project and workspace information right click on your project(s) and choose refresh. Then go to project in the menu on top of the window and click "clean".

This typically does what you need.

If it does not try to remove project from the workspace (just press "delete" on the project and then say that you DO NOT want to remove the sources). Then open project again.

If this does not work too, do the same with the workspace. If this still does not work, perform fresh checkout of your project from source control and create new workspace.

Well, this should work.

Answer 3

You can always create a new Eclipse workspace. The Eclipse.exe -clean option is not sufficient in some cases, for example, if the local history becomes a problem.

Edit:

Eclipse is mostly a collection of third party plugins. And each of those plugins can add some extra useful, useless or problematic information to the central Eclipse workspace meta-data folder.

The problem is that not every plugin participates during the user-issued cleanup routine. Therefore, I'd say that it is a problem in the system design of Eclipse, that it allows plugins to misbehave like this.

And therefore, I'd recommend to make yourself comfortable with the idea of using multiple workspaces and linking-in external project entities into each workspace. Because, this is the only workaround for the given system design, to handle faulty plugins that spam your workspace.
