Re: [tycho-user] tycho-demo pom first: the bundle except test bundle not started
|
Igor,
You are right. Adding both both Bundle-Activator and Bundle-ActivationPolicy solve the issue.
But I wonder if it works well for organizing bundles into interfaces-only bundles and implementation bundles, so I refactor pomfirst-bundle into pomfirst-bundle-api (only including PomFirst interface) and pomfirst-bundle-impl (including the implementation of PomFirst interface). The PomFirst service is registered in the implementation bundle. Now the test bundle failed because PomFirst service is not registered (the activator in pomfirst-bundle-impl not started).
This time even I added "tycho.demo.itp02.pomfirst-bundle-impl" to the <bundleStartLevel> of the test bundle, its activator still not started.
Can you check how tycho test works in this case?

Thanks for your help.
Guofeng

Like I said, you need to specify both Bundle-Activator and Bundle-ActivationPolicy.
