Issue: SCR Annotated Services not working
Hi Team,
I am working on an OSGI project where I am upgrading jetty and OSGI
versions from R-4.9 to R4_19_maintenance and Jetty version is getting
upgraded from 9.4.11 to 9.4.44
I was using org.eclipse.equinox.ds(1.4.400) as a bundle earlier which was
using org.apache.felix internally.
Since org.eclipse.equinox.ds dependency has been removed from
R4_19_maintenance, I have added dependency of org.apache.felix.scr(2.1.24)
but the issue is org.apache.felix.scr.annotation services are not getting
activated.
Can you please help me in knowing if it is the version of
org.apache.felix.scr.annotation that is causing the issue, if yes, which
version it supports or what could be the possible issues that might be
causing this.
Thanks & Regards,
Kanika

Also, just so that we understand each other very clearly, you never needed
org.apache.felix.scr.annotation in order for Felix SCR to work in the first
place.
Any components (@org.osgi.service.component.annotations.Component) that
previously worked on equinox.ds should simply _work_ (except for some very
rare edge cases) when switching to felix.scr.
Also, felix.scr bundles the packages `org.osgi.service.component(.runtime)`
so there isn't actually a need for providing an API jar for those.
(All these sorts of issues are generally caught by using the resolver for
assembling the runtime ;) though the resolver output is often esoteric and
difficult to mentally parse. Ahh to have all the time in the world...)

Hi Kanika,
As you are using not-that-old version of SCR bundle, you can use org.osgi:osgi.annotation:7.0.0 for your components to be used in compile time.
For your information, the latest version of SCR bundle is org.apache.felix:org.apache.felix.scr:2.1.30 which works with OSGi R7 and org.apache.felix:org.apache.felix.scr:2.2.0-RC1 for OSGi R8.
Best Regards,
Amit

Hi Kanika,
Felix SCR bundle processes service components from bundles by reading the SCR XML files stored inside the OSGI-INF directory. The annotations which you are using are all build time annotations, that means, external tooling such as bndtools or bnd maven plugin reads annotated Java classes (SCR components) and generates the XML files in the aforementioned directory inside the bundle which in runtime is processed by SCR bundle.
The SCR annotations bundle you mentioned can, therefore, be removed from your OSGi runtime as it is not meant to be installed at all.
I hope it helps. If you need further assistance, please don't hesitate to contact once again.
Best Regards,
Amit

Hi Kanika,
Felix SCR bundle processes service components from bundles by reading the SCR XML files stored inside the OSGI-INF directory. The annotations which you are using are all build time annotations, that means, external tooling such as bndtools or bnd maven plugin reads annotated Java classes (SCR components) and generates the XML files in the aforementioned directory inside the bundle which in runtime is processed by SCR bundle.
The SCR annotations bundle you mentioned can, therefore, be removed from your OSGi runtime as it is not meant to be installed at all.
I hope it helps. If you need further assistance, please don't hesitate to contact once again.

Amit
