Issue with upgrading to Bamboo DC 10.x (open symphony)

We are trying to update our bamboo plugin to be compatible with Bamboo DC 10.x.
We followed this guide and this guide.
But now we are getting this issue :
Caused by: org.osgi.framework.BundleException: Unable to resolve com.qasymphony.qtest-plugin-for-bamboo [123](R 123.0): missing requirement [com.qasymphony.qtest-plugin-for-bamboo [123](R 123.0)] osgi.wiring.package; (&(osgi.wiring.package=com.opensymphony.module.propertyset)(version>=1.5.0)(version<=1.5.0)) Unresolved requirements: [[com.qasymphony.qtest-plugin-for-bamboo [123](R 123.0)] osgi.wiring.package; (&(osgi.wiring.package=com.opensymphony.module.propertyset)(version>=1.5.0)(version<=1.5.0))]

I removed every opensymphony dependency as per the documentation and yet it still asks for it and in the other hand it says :
Package com.opensymphony.module.propertyset is internal and is not available for export to plugin com.qasymphony.qtest-plugin-for-bamboo

I’m not sure how to proceed from here, should it be there or not? can you please help? Thanks
