How to remove the contents of persisted values on uninstall of intellij plugin?

Hi,

  I am developing an intellij plugin and it persists some values in example.xml like this:-

@State(name = "CloudConfig", storages = @Storage("example.xml"))

I want to remove these values upon uninstall of the plugin.For that i have implemented

StartupActivity interface and wrote the code like this:-

@Override
public void runActivity(@NotNull com.intellij.openapi.project.Project project) {
    com.intellij.ide.plugins.PluginInstaller.addStateListener(new PluginStateListener() {
        @Override
        public void install(@NotNull IdeaPluginDescriptor ideaPluginDescriptor) {
            LOG.info("installing plugin");
        }

        @Override
        public void uninstall(@NotNull IdeaPluginDescriptor ideaPluginDescriptor) {
            LOG.info("Uninstalling plugin");
           

        }
    });
}

Could you suggest how to locate the example.xml and remove the contents?
