How to determine my plugin's runtime dependencies?

[Victor Cheung]

Hello,

After installing my plugin into JIRA, it warns me that "one or more modules is missing dependencies".

And as a result, my plugin is not enabled after installation (and cannot be enabled).

I've checked and the error logs are not helpful at all.

How can I find out what are the run-time dependencies of my plugin?  I am now suspecting that perhaps I need to add additional classes/packages into my pom.xml in the <import-package> section.  Alternatively, how can I determine what jars/libraries/classes are provided by my host JIRA instance (including those that are indirectly provided through other installed plugins which have exported their jars/libraries)?

Thanks in advance!

Hello,

Try to enable this plugin again and look in the logs. Usually there are helpful messages when enabling a plugin.

Hi Alexey, 

Thanks for your reply!  I wish you were right, because I posed this question exactly because the error log was not that helpful to me which was/is the following:

 As you can see, the error is complaining about some kind of parsing error with my plugin-context.xml file which is:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:atlassian-scanner="http://www.atlassian.com/schema/atlassian-scanner"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
 http://www.atlassian.com/schema/atlassian-scanner
 http://www.atlassian.com/schema/atlassian-scanner/atlassian-scanner.xsd">
 <atlassian-scanner:scan-indexes/>
</beans>

I don't see anything wrong with the plugin-context.xml file.  Furthermore, my plugin installs without any problems on another JIRA 7.2.8 instance -- it's only having this error on our Unix instance version of JIRA 7.2.8 and I'm trying to troubleshoot why.  I'm at a loss since the error seems wrong/misleading.

Try to clean the osgi cache in the broken Jira instance:

1. Stop the JIRA instance
2. Delete JIRA_HOME/plugins/.bundled-plugins and JIRA_HOME/plugins/.osgi-plugins (just these two)
3. Restart JIRA

If it is a production instance, Kindly make a backup first.

Thank you, Alexey!  I will try your suggestion and will report my results!
