On the bottom of my JIRA instance, I have the following displayed:

"Bug tracking and project tracking for software development powered by Atlassian JIRA (v5.1.1#772-sha1:unknown) Report a problem"

Why is it saying sha1:unkown? What's going on with this? This is a JIRA install that was built from the source. What can be done about this?

Hi Selbch,

What Java JDK are you using?

I'm wondering, because sometimes it occurs when is used JDK 7.


I am using JDK 1.6_35. How can I get this "unknown" to go away?

Hi Selbch,

Have you customized something in JDK? Perhaps there is a misconfiguration on it, once the hash function SHA-1 is not being recognized properly.

You may could try to install a new JDK to see if the "unknown" message will keep appearing?

Hi Fagner,

I have not actually customized anything in the JDK, so I'm still a little confused as to why the SHA: unknown is showing up.

I installed a new JDK 1.6_37, and the "unknown" message is still appearing.

The unknown part seems to be a build or release string. If you built it yourself it's probably to be expected. You can cheat it by hiding the footer by adding this to your announcement banner:


To fix it I would either reinstall or open a support ticket with atlassian.
