I created a Custom Filed class extending GenericTextCFType.
And atlassian-plugin.xml looks as below.
<customfiled-type key="aaa" class="***.TestCustomField">
<resource type="velocity" name="edit" location="templates/edit.vm"/>
</customfiled-type>
When it is installed, JIRA displays the warning as below.
[This plugin has one or more modules with missing dependencies.]
And the "aaa" module is disabled.
What dependencies are needed?
