How to clear the SpringSource Tool Suite cache?

Question

I have installed SpringSource Tool Suite (STS) version 3. I created two Maven projects: a console application and a web Maven application. I tried to open Main.java in Eclipse, but without success. I tried to restart STS, but receive this error:

!SESSION 2012-06-09 09:13:29.626 -----------------------------------------------

I suppose that I need to clear some cache. Is that correct? Where is it?

Solution 1

Perhaps you could solve it starting Eclipse with the -clean option

How to run eclipse in clean mode? and what happens if we do so?

Solution 2

Edit file "ECLIPSE_HOME\configuration\config.ini" change

osgi.bundles=reference\:file\:org.eclipse.osgi_3.6.2.R36x_v20110210.jar@4,reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.200.v20100503.jar@1\:start

To

osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.200.v20100503.jar@1\:start
