Osgi.extender - Unresolved requirements

Hi,

I am getting this error when building my plugin for Confluence 7, it builds ok for Conlfuence 6.

Getting this error
osgi.extender; (&(osgi.extender=osgi.component)(version>=1.3.0)(!(version>=2.0.0))) Unresolved requirements

Any hints or directions are very welcome.
