In JIRA v5.0 we are creating a separate API module for plugin developers to depend on to give more security that the plugin will remain compatible with future JIRA versions.

Plugins devs can change the dependency on "atlassian-jira" to "jira-api" in their maven pom.xml like so:

        <dependency>
            <groupId>com.atlassian.jira</groupId>
            <artifactId>jira-api</artifactId>
            <version>${jira.version}</version>
            <scope>provided</scope>
        </dependency>     

This issue is intended to gather feedback on what is included and what isn't included, and is of particular interest for JIRA v5.0 Early Access releases (milestones and betas).
