pom dependency for AbstractEditConfigurationItemAction?

[KC Wong]

I'm trying to add configuration to my plugin, but the project (generated using PluginSDK) does not include AbstractEditConfigurationItemAction (class definition not found). 

What is its pom dependency?

[KC Wong]

pom generated by pluginSDK has this commented out: 

<!-- Add dependency on jira-core if you want access to JIRA implementation classes as well as the sanctioned API. -->
<!-- This is not normally recommended, but may be required eg when migrating a plugin originally developed against JIRA 4.x -->
<!--
<dependency>
<groupId>com.atlassian.jira</groupId>
<artifactId>jira-core</artifactId>
<version>${jira.version}</version>
<scope>provided</scope>
</dependency>
-->

Once uncommented, the class AbstractEditConfigurationItemAction can be found.

But is that still the recommended way to develop a plugin with configuration, as the comment suggests a new way?
