Maven bundle packaging problem, known as MNG-4338

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

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>
