Jira 3 has reached its end of life. I do not think you will find it unless someone sends it to you. There is a tag in the source tree so you should be able to get the sources and build it. Building may not be so easy if you don't already have the development environment.
i tried to build but i can't finish due to missing dependencies.
the source contains repositories that don't even exist any longer.
i think you should...
1. ask atlassian or atlassian experts like Norman suggested
2. find someone using the same version you have and ask for this plugin jar you need
3. consider upgrading to a more recent version (there are many)
i am sorry i can't tell you more
I do not have that version of the development environment. My only suggestion is to checkout Atlassian's experts site and see if you can find a consultant that do this for you.
I am assuming upgrading is not a possibility at this time.
Did you tried searching Atlassian maven repo, I couldnt find exact 0.10.3 but I guess you can try some other version with minor changes. Here is a url for repo
Hope this helps.
