Maven bundle packaging problem, known as MNG-4338 - apache

Question

I'm having trouble with the maven-bundle-plugin:
I want to deploy my project as a osgi bundle, wherefore I use the packaging as bundle.
But it seems that the pom does not know a packaging as a bundle. Here you can see my pom.xml:
<project ...>...
<packaging>bundle</packaging>
<version>1.0.0</version>
<name>Simple CXF project using spring configuration</name>
<properties>
<cxf-version>2.4.2</cxf-version>
</properties>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<version>2.3.5</version>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.groupId}.${project.artifactId}</Bundle-SymbolicName>
<Bundle-Name>${project.name}</Bundle-Name>
<Bundle-Version>${project.version}</Bundle-Version>
<Export-Package>demo.hw.server</Export-Package>
<Bundle-Activator>demo.hw.server.Activator</Bundle-Activator>
<Require-Bundle>org.apache.cxf.bundle</Require-Bundle>
</instructions>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
<dependencies>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-frontend-jaxws</artifactId>
<version>${cxf-version}</version>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-http</artifactId>
<version>${cxf-version}</version>
</dependency>
<dependency>
<groupId>org.apache.felix</groupId>
<artifactId>org.osgi.core</artifactId>
<version>1.4.0</version>
</dependency>
</dependencies>
</project>
They say, this bug has already been fixed (http://jira.codehaus.org/browse/MNG-4338), but to me it seems it hasn't. Has anyone encountered this problem before and found a solution?
The Error message is like this:
[INFO] Scanning for projects...
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]
[ERROR] The project com.talend.liugang.cxf:java_first_jaxws:1.0.0 (C:\Users\Andreas\workspace\java_first_jaxws\pom.xml) has 1 error

Answer 1

Given your pom example above, you should just move the maven-bundle-plugin outside of the <pluginManagement> node. <pluginManagement> is normally used for inheritance purposes in parent poms. The bundle packaging type is provided by the maven-bundle-plugin (which is why you need <extensions>true</extensions>), so this plugin is required to be outside <pluginManagement> in this case.
<project ...>...
<packaging>bundle</packaging>
<version>1.0.0</version>
<name>Simple CXF project using spring configuration</name>
<properties>
<cxf-version>2.4.2</cxf-version>
</properties>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
</plugins>
</pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<version>2.3.5</version>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.groupId}.${project.artifactId}</Bundle-SymbolicName>
<Bundle-Name>${project.name}</Bundle-Name>
<Bundle-Version>${project.version}</Bundle-Version>
<Export-Package>demo.hw.server</Export-Package>
<Bundle-Activator>demo.hw.server.Activator</Bundle-Activator>
<Require-Bundle>org.apache.cxf.bundle</Require-Bundle>
</instructions>
</configuration>
</plugin>
</plugins>
</build>
<dependencies>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-frontend-jaxws</artifactId>
<version>${cxf-version}</version>
</dependency>
<dependency>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-rt-transports-http</artifactId>
<version>${cxf-version}</version>
</dependency>

<version>1.4.0</version>
</dependency>
</dependencies>
</project>

Answer 2

Yeap, the issue is that <groupId>org.apache.felix</groupId> needs to be outside of the <pluginManagement>.

Answer 3

I see a similar issue. It occurs to me that it happens when the group id ends like the artifact id starts. I try to bundle something like that:
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api.plugin</artifactId>
The slf4j from the artifact id is deleted at it ends up like: org.slf4j.api.plugin in the Manifest as symbolic name.
