org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource '/templates/macros/navmap-mytheme.vm'
at org.apache.velocity.runtime.resource.ResourceManagerImpl.loadResource(ResourceManagerImpl.java:501)
at org.apache.velocity.runtime.resource.ResourceManagerImpl.getResource(ResourceManagerImpl.java:384)
Cause
If you are using a Navigation Map Macro with a theme, like:
1
2
{navmap:mylabel|theme=mytheme}
Confluence looks for pages with the label set to "mylabel" and locate the navmap-mytheme.vm file in WEB-INF/classes/templates/macros directory. If the vm file does not exist, Confluence will throw the above error saying that it is unable to find the file.
Such error usually happens due to a copy and paste of the macro from the documentation page when testing for the macro functionality. A user might be using the macro without knowing that it refers to a custom setting for navmap macro, which is defined in the vm file.
Resolution
Remove the reference to the file if you are not using a customised navmap macro.
