If you try to build any confluence plugin in maven 2 against confluence 2.6.0 as a dependency it claims that ofbcore-entity is not available (because the version it is looking for is not available via repository.atlassian.com.

To "fix" this currently a confluence plugin can build against confluence 2.6.0 as a dependency by adding:

<dependency>
<groupId>ofbcore</groupId>
<artifactId>ofbcore-entity</artifactId>
<version>2.1.1-atlassian-16Oct06</version>
<scope>provided</scope>
</dependency>

to the pom.xml since that version of ofbcore-entity IS available via repository.atlassian.com, even though it was not the one that confluence 2.6.0 was built against as it is a different version.

It appears though if you build a confluence plugin against that entity ofbcore version and confluence version 2.5.3 as a dependency (to try to make the plugin compatible with 2.5.x and 2.6.x) that does not work. I think that we will end up having to have a version of our Custom Space User Management plugin for 2.3.x-2.5.x and another one for 2.6.x-(until the next major API change like this).
