How to make deleted items in "show view" invisible in Eclipse RCP?

Question

I'm creating a web development framework with Eclipse RCP.

I did not need the view I made, so I removed the code below and the icon image from plugin.xml.

    <extension point="org.eclipse.ui.views">
        <view
            category="..."
            name="..."
            icon="..."
            class="..."
            id="..."
            >
    </extension>

By the way, I see the removed item in "show view". The icon shows a red square.

How do I remove it?

Enable the "Clear the configuration area before launching" checkbox in your launch configuration. plugin.xml contents are cached otherwise.
