I have JIRA 5.1.5 (atlassian-jira-5.1.5-x32.bin) on Ubuntu and I'm trying to install Greenhopper. Should be easy, just use the Atlassian Marketplace but it is not working. The message is the same everywhere: "the Atlassian Marketplace server is not reachable".
From quick search on the internet I conclude that this is a well reported problem going back to JIRA-version-a-long-time-ago. Forum mentions that JIRA will pick up proxy settings from the host but I know for a fact that this is not true. Still not true. What is the latest and greatest? Can JIRA marketplace run from behind proxy? Will it run at all?
How can plugins be installed easily without marketplace?
