you have newline between 2 imported packages:
import-package: org.osgi.framework, tutorial.example2.service can try put both on same line:
import-package: org.osgi.framework, tutorial.example2.service i guess in current manifest import-package ignored syntax invalid. bundle resolves fine not import packages. when activator run can not find external classes.
