Failure Processing JSPC

[niravdangi]

I need to integrate Apple Push Notification Service to Openfire.
For that I had followed openfire-apns-plugin. But when I am executing mvn clean install command (last step), I am getting error. So, because of that openfire-apns.jar is not created.

Please help me to figure out this issue.
Following log is generated after executing mvn clean install,

The jspc target of the plugin used java 1.5 which generated an error. Also the encoding was not initialized. I had to fixe the plugin for it.
