ClassNotFoundException: com.atlassian...SpacePermissionCondition

[Claudio Kirchhoff]

Hi,

I have tried to follow this tutorial: https://developer.atlassian.com/confdev/tutorials/space-admin-screens/writing-a-space-admin-screen. My confluence version is 6.0.2.

Unfortunately I was not able to build my project because of the following error (scroll further down for a complete stack trace):

java.lang.ClassNotFoundException: com.atlassian.confluence.plugin.descriptor.web.conditions.SpacePermissionCondition

I am rather puzzled by this, because I did find the SpacePermissionCondition.class file in the confluence jar in my target directory. Right next to the SpaceSidebarCondition.class which implements the other condition used in the same tutorial. If I remove the SpacePermissionCondition and leave only the SpaceSidebarCondition in place I get no error.

I have looked at the pom.xml and the atlassian-plugin.xml files in the source code for the tutorial which is located here: https://bitbucket.org/atlassian_tutorial/space-plugin-example, but I could not find anything that seemed relevant to me, which I could be missing.

Other things I have tried: use an older version of confluence, atlas-mvn clean, delete my local maven repository. To no avail.

I can go on without the condition for now, but I would like to use it later on. Also, I would just like to know what's going on. Does someone have an idea what I could be missing?

Thanx in advance for any help on the matter!

Here, as promised, the stack trace:

Well, my next try to create a space admin screen in an actual project was successful. Still don't know what went wrong the first time, but at leas my problem is gone
