How do I fix an error in enabling the plugin for the writing a space admin screen tutorial?

[Diana Bianco]

Hi,

I am new to this. I was wondering if someone could help me. I've been patiently working my way through the writing a space admin screen. When I go into confluence the plugin is there but it says it is disabled due to an error (see below)

2020-06-23 12:31:42,658 ERROR [main] [atlassian.plugin.manager.DefaultPluginManager] enableConfiguredPluginModule There was an error loading the descriptor 'Quick Link Manager in Space Admin' of plugin 'com.example.plugin.tutorial.confluence.tutorial-confluence-notification2'. Disabling.

 Caused by: com.atlassian.plugin.PluginParseException: Unable to load the module's display conditions: java.lang.ClassNotFoundException: com.atlassian.confluence.plugin.descriptor.web.conditions.SpacePermissionCondition not found by com.example.plugin.tutorial.confluence.tutorial-confluence-notification2 [288]

When I go into my atlassian-plugin.xml and delete the "Item in Space Tools" and the Item in Space Admin (for doc theme) it enables. but then of course it does not work. I don't know what my error is.

atlassian-plugin.xml
