Subject [jira] [Commented] (FELIX-4135) Bnd scrplugin contrib
Date Sat, 10 Aug 2013 14:26:47 GMT

    [ https://issues.apache.org/jira/browse/FELIX-4135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13735924#comment-13735924

Pierre De Rop commented on FELIX-4135:

Hi Carsten;

> - I'm wondering if we should return "false" from the analyzeJar method?

I do agree (thanks for pointing out this). This method should return false because the plugin
does not modify the classpace.
I've committed a fix for this in rev 1512721.

> I think the ds annotations are already processed by bnd, so we don't need to process
them within this plugin

Indeed, if the "-dsannotations: *" directive is specified in the bnd configuration, then DS
annotations are parsed by bnd itself.
I also fixed the pom.xml in rev 1512721. in order to remove all references to the "org.apache.felix.scr.ds-annotations"
artifact, so it won't be used at all.

This means that if a bundle contains a mix of DS/SCR annotations, then the "-dsannotation:
*" directive has to be specified in the bnd config. 
For example:

  -plugin: org.apache.felix.scrplugin.bnd.SCRDescriptorBndPlugin
  -dsannotations: *

(if someone asks in the future to be able to choose between the bnd or scrplugin DS annotations
scanner, then in a later version, perhaps we will consider to add a new property in the plugin
in order to enable/disable the ds scanner in the bnd scrplugin ?)

> the "Service-Component" header is overwritten, maybe we should append in order to play
well with other plugins

Yes, I also fixed this in rev 1512721.

> This issue is related to the following post, which is about writing a bndtools plugin
for the Apache Felix Scrplugin annotations:
>  http://www.mail-archive.com/dev@felix.apache.org/msg29200.html
> If this may help, I have attached to this issue a simple BND plugin, which internally
invokes the SCRDescriptorGenerator in order to generate the descriptors for Apache Felix Scr
annotations, as well as DS 1.2 annotations (using the scrplugin generator).
> Basically, just adding the following parameter in a directives.bnd file allows to invoke
the plugin:
>     -plugin org.apache.felix.scrplugin.bnd.SCRDescriptorBndPlugin;destdir=target/classes
> I did some tests using a BND Ant task, and it seems to work, and will try to do a test
with bndtools this week (for now I don't know how to add a plugin in bndtools, but I guess
it's easy).
