Subject Weird bugs with tutorial/maven
Date Fri, 02 Apr 2010 09:35:52 GMT
Hi all, i'm currently playing with Felix tutorial.
By use, I do it with maven projects; Tht's to say that, as an example,
I've made the translation service a maven module in my project, and
created the pom file accordingly.
As a consequence, my pom looks like this :

<project>
	<parent>
		<artifactId>jypsy</artifactId>
		<groupId>com.mycompany</groupId>
		<version>0.0.1-SNAPSHOT</version>
	</parent>
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.mycompany.pss</groupId>
	<artifactId>translation-english</artifactId>
	<packaging>bundle</packaging>
	<name>translation-english</name>
	<version>0.0.1-SNAPSHOT</version>
	<url>http://maven.apache.org</url>
	<dependencies>
		<dependency>
			<groupId>org.apache.felix</groupId>
			<artifactId>org.osgi.core</artifactId>
		</dependency>
	</dependencies>
	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.felix</groupId>
				<artifactId>maven-bundle-plugin</artifactId>
				<extensions>true</extensions>
				<configuration>
					<instructions>
						<Export-Package>com.mycompany.translation.api.*</Export-Package>
						<Private-Package>com.mycompany.translation.english.*</Private-Package>
						<Bundle-Activator>com.mycompany.translation.Activator</Bundle-Activator>
					</instructions>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

As one may guess, i have a superpom which eases me the task of
declaring attributes of my manifest, using the following template :

				<plugin>
					<groupId>org.apache.felix</groupId>
					<artifactId>maven-bundle-plugin</artifactId>
					<version>1.4.0</version>
					<extensions>true</extensions>
					<configuration>
						<instructions>
							<Bundle-SymbolicName>${pom.groupId}.${pom.artifactId}</Bundle-SymbolicName>
							<Bundle-Name>${pom.name}</Bundle-Name>
							<Bundle-Version>${pom.version}</Bundle-Version>
						</instructions>
					</configuration>
				</plugin>


But there is something I don't understand : the generated manifest has
a set of import package that *precisely* contains my package classes :

Manifest-Version: 1.0
Export-Package: com.mycompany.translation.api
Private-Package: com.mycompany.translation.english
Built-By: ndx
Tool: Bnd-0.0.238
Bundle-Name: translation-english
Created-By: Apache Maven Bundle Plugin
Bundle-Vendor: mycompany
Build-Jdk: 1.6.0_16
Bundle-Version: 0.0.1.SNAPSHOT
Bnd-LastModified: 1270200175640
Bundle-ManifestVersion: 2
Bundle-Activator: com.mycompany.translation.Activator
Bundle-Description: A project
Import-Package: com.mycompany.translation,com.mycompany.translatio
 n.api
Bundle-SymbolicName: com.mycompany.translation-english
Bundle-DocURL: http://www.perdu.com

And, as a consequence, when dropping that bundle in Felix, I get an exception :

ERROR: Error starting
file:/C:/java-ext/felix-framework-2.0.4/bundle/translation-english-0.0.1-SNAPSHOT.jar
(org.osgi.fr
amework.BundleException: Unresolved constraint in bundle
com.mycompany.translation-english [7]: package; (package=com.
mycompany.translation))
org.osgi.framework.BundleException: Unresolved constraint in bundle
com.mycompany.translation-english [7]: package; (p
ackage=com.mycompany.translation)->

Here I can see the generated Import-Package clause is wrong.
So, what can I do to avoid/correct that ?

Thanks
