Package uses conflict: Import-Package: org.osgi.service.blueprint

Hello,

We have a bundle with blueprint (OSGI-INF/blueprint/xxx.xml) and build with maven-bundle-plugin. 
The META-INF/ MANIFEST.MF contains: 
......
Import-Package: ...,org.osgi.service.blueprint;version="[1.0.0,2.0.0)",...

When install this bundle into Karaf 2.2.4, got error: 
Reason: Package uses conflict: Im port-Package: org.osgi.service.blueprint; version="[1.0.0,2.0.0)"

Why it complains there has conflict? 

Thanks.
Xilai

yes, the maven-bundle-plugin will read the MANIFEST.MF of the third party
bundle, if it exports the package with some kind version number like
1.2.1.  maven-bundle-plugin will generated the import package with the
version rang of [1.2, 2).
You can override it by specify the import package version rang in the
maven-bundle-plugin.

Re: Package uses conflict: Import-Package: org.osgi.service.blueprint

Posted by David Jencks <da...@yahoo.com>.

This import-package is reguired by the blueprint spec so that only one blueprint implementation can process the blueprint plan.  The only way I can imagine to get this uses conflict is if you have two blueprint implementations running in karaf.  Do you?  Do you need both?

thanks
