Whenever I upload a plugin in JIRA an error message comes up and the install screen never closes

[John Kelly]

After updating UPM (now 2.19.4) whenever I upload an add-on from a .jar file, I get a message "Error" in the background in a red box, and the install box with the spinner never closes.  I've tried several different plugins (my own jars and downloaded from the marketplace), and all seem to trigger this behavior:

There are no errors in the log and if I close the browser window and go back into JIRA the plugin seems to have installed just fine, so this seems to be a completely innocuous error.

Increase plugin timeout to 300 in the java_opts. that might helps if above of the steps doesn't work.

Thanks,

Sumit

Please try these steps and see if it helps,

1. perform a complete re-indexing
2. Clear the plugin cache folders
3. Reboot the application
4. Check the log files for errors

This should solve your problem

Try to use Incognito mode of your browser thats works for me!

Thank you both for your responses.  

I followed Pilar's steps several times, but I continue to receive the error when installing a plugin from .jar (installing from the marketplace works without error).

The log shows:

As you can see, the plugins appear to install correctly and are enabled, it's just the error on the front end that is distressing.

Sumit, I set the -Datlassian.plugins.enable.wait=300 but there was no change aside from the log message now states: "[com.lbcg.jira.plugins.bulkclone.BulkClone], 300 seconds remaining".
