Upgrading to Power Apps 6.0.820.x Fails

Problem

Additional Background

If you have installed or upgraded any addons from the Power Apps suite version 6.0.820.x before upgrading to Java 11, they will fail.

Solution

Either upgrade Jira to Java 11 or downgrade Power Apps to a version prior to 6.0.820.x. To downgrade Power Apps, follow these steps:

• Uninstall all Power Apps. In particular, uninstall:

  • Power Scripts

  • SIL Engine

  • Power Apps Licensing Manager (formerly Warden)

• Stop Jira

• Clear the plugin cache. Delete <JIRA_HOME>/plugins/.bundled-plugins and <JIRA_HOME>/plugins/.osgi-plugins (just these two folders)

• Manually remove any Power Apps with version 6.0.820.x found in <JIRA_HOME>/plugins directory. In particular, look for the following names:

  • power-scripts

  • katl-commons (SIL Engine)

  • warden (Power Apps License Manager)

• Restart JIRA.

• Download Power Apps from the Atlassian Marketplace.

• Install Power Apps manually in the following order:

  • SIL Engine (Power Apps Licensing Manager installs automatically).

  • Power Scripts

  • All other Power Apps
