possible to extend jira-gadget-plugin

[leonliusg]

Hi guys,

We want to create a new reporting chart for Jira 5.2, we need to extend some class in jira-gadget-plugin module, which is showing in plugins\.bundled-plugins (it will be loaded as osgi module in plugins\.osgi-plugins).

I have pom.xml amps config section like the following:

<plugin>
                <groupId>com.atlassian.maven.plugins</groupId>
                <artifactId>maven-jira-plugin</artifactId>
                <version>${amps.version}</version>
                <extensions>true</extensions>
                <configuration>
                    <productVersion>${jira.version}</productVersion>
                    <productDataVersion>${jira.version}</productDataVersion>
                    <pluginDependencies>
                        <pluginDependency>
                            <groupId>com.atlassian.jira</groupId>
                            <artifactId>jira-gadgets-plugin</artifactId>
                        </pluginDependency>
                    </pluginDependencies>
                    <instructions>
                        <Import-Package>
                            com.atlassian.jira.gadgets*;version="0.0"
                        </Import-Package>
                    </instructions>
                </configuration>
</plugin>

But when I trying to install my plugin, I found the following error

Caused by: org.osgi.framework.BundleException: Unresolved constraint in bundle test.myplugin [103]: Unable to resolve 103.0: missing requirement [103.0] p
ackage; (&(package=com.atlassian.jira.gadgets)(version>=0.0.0))

        at com.atlassian.plugin.osgi.factory.OsgiPlugin.enableInternal(OsgiPlugin.java:417)
        ... 90 more

Does any one know why the error occured? And how can I extend the classes in the jira bundled plugins?

The following is what I guess, it is because the OSGI Manifest file for jira-gadgets-plugin does not have "Export-Package", the following is part of the manifest file for jira-gadgets-plugin:

Manifest-Version: 1.0
Private-Package: script.chartpopup,templates,com.atlassian.jira.gadget
 s.system,com.atlassian.jira.chartpopup,.,script,com.atlassian.jira.st

......

Many thanks all.

Last time I tried to extend a standard JIRA gadget I ended up copying a lot of the source code and changing the Java package :-( It doesn't feel like this was a use case that was really considered when gadgets were created.
