How to clear the SpringSource Tool Suite cache?
caching, eclipse, java, maven, project
Solution
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?
Problem
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 ----------------------------------------------- eclipse.buildId=3.0.0.201205010613-M1-e42 java.version=1.7.0_04 java.vendor=Oracle Corporation BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US Framework arguments: -product com.springsource.sts.ide Command-line arguments: -os win32 -ws win32 -arch x86 -product com.springsource.sts.ide !ENTRY org.eclipse.osgi 4 0 2012-06-09 09:13:30.552 !MESSAGE FrameworkEvent ERROR !STACK 0 org.osgi.framework.BundleException: Exception in org.eclipse.osgi.framework.internal.core.SystemBundleActivator.start() of bundle org.eclipse.osgi. at org.eclipse.osgi.framework.internal.core.BundleContextImpl.startActivator(BundleContextImpl.java:734) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.start(BundleContextImpl.java:683) at org.eclipse.osgi.framework.internal.core.InternalSystemBundle.resume(InternalSystemBundle.java:225) at org.eclipse.osgi.framework.internal.core.Framework.launch(Framework.java:657) at org.eclipse.core.runtime.adaptor.EclipseStarter.startup(EclipseStarter.java:274) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:176) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:629) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:584) at org.eclipse.equinox.launcher.Main.run(Main.java:1438) Caused by: java.lang.IllegalStateException: Expected to find an object at table index: 1008 ``` I suppose that I need to clear some cache. Is that correct? Where is it?
