There has been a couple reports of failed project imports due to incompatible Greenhopper versions between source and destination instances. In the UI it appears that all everything matches up, however taking a closer look in the database, or XML backup, the inconsistencies start to unravel.

From the XML backup we noticed the following.

application properties section:

     com.pyxis.greenhopper.jira:build              : 33

User plugins section:

Atlassian GreenHopper                         : com.pyxis.greenhopper.jira
         Version                                       : 6.2.1

The above looks like the version is 6.2.1. Digging deeper though we find in the same XML backup the version is different:

<PluginVersion id="10100" name="GreenHopper" key="com.pyxis.greenhopper.jira" version="5.7.4" created="2012-06-22 15:35:34.0"/>
<PluginVersion id="10100" name="GreenHopper" key="com.pyxis.greenhopper.jira" version="5.8.7" created="2012-06-22 15:35:34.0"/>
<PluginVersion id="12001" name="Atlassian GreenHopper" key="com.pyxis.greenhopper.jira" version="6.1.6" created="2013-04-10 09:13:56.11"/>

Running the following query on the database where the XML was generated from shows the latest version of 6.1.6 as well:

select * from propertystring where id=(select id from propertyentry where property_key='GreenHopper Version');

Resolution

• Restarting JIRA appears to update the inconsistent version stored in the database, which should ensure any XML backup generated after that contains consistent version numbers.
