Question

From an official Eclipse plugin development tutorial, I copied the following code to define a new button in my plugin.xml

<extension point = "org.eclipse.ui.actionSets">
        <actionSet
            id="org.eclipse.examples.helloworld.HelloWorldActionSet"
            label="Hello World"
        visible="true"
        description="The action set for the Eclipse Hello World example">
        <menu
        id="org.eclipse.examples.helloworld.HelloWorldMenu"
        label="Samples">
        <separator name="samples"/>
        </menu>
        <action id="org.eclipse.examples.helloworld.actions.HelloWorldAction"
        menubarPath="org.eclipse.examples.helloworld.HelloWorldMenu/samples"
        toolbarPath="Normal"            
        label="Hello World"
        tooltip="Press to see a message"
        icon="icons/helloworld.gif"
        class="org.eclipse.examples.helloworld.HelloWorldAction"/>
        </actionSet>
    </extension>

But unfortunately, I get some deprecated warnings. Especiall for the extension point and the actionset. I couldn’t find any information how to avoid that. Any hints?

The problem is that the whole action framework is deprecated. Nowadays, one uses commands instead. You can find more information about commands for instance eclipse-tips.com or vogella.com.
