症状

You try to update JIRA Agile 6.2.4.1 to the latest version via the Universal Plugin Manager in JIRA, however the Update button could not be found:

原因

JIRA Agile version 6.2.4.1 has been removed from the Marketplace servers, hence the updates for this version could not be found as well.

ソリューション

Manually update your JIRA Agile plugin.

• Download the latest JIRA Agile jar file from here: https://marketplace.atlassian.com/plugins/com.pyxis.greenhopper.JIRA
• Install the plugin by file upload using this documentation: https://confluence.atlassian.com/display/UPM/Installing+Add-ons#InstallingAdd-ons-Installingbyfileupload 
• Simply upload the downloaded JAR to JIRA, and the upgrade tasks will run and your GreenHopper will be upgraded.

Always have a JIRA XML or database backup handy before upgrading JIRA Agile.
