Howto install Jira plugins using Jira on JBoss

I must say most of the documentation on Atlassian’s web site refers to the installation of plugins on the Jira standalone installation. So it took some time to determine exactly what to do with when trying to install a plugin with our installation that is running on JBoss. The process is as follows: Download the plugin jar, copy it to: atlassian-jira-enterprise-3.13.2/webapp/WEB-INF/lib/, this is your jira build directory. Build the war file by executing ./build.sh in the atlassian-jira-enterprise-3.13.2 directory. This will build a new war file. Copy this into your JBoss deploy folder e.g. jboss-4.2.3.GA/server/all/deploy/ and restart JBoss.  The new war will not lose your existing projects that were running with the previous war file.
