karaf-maven-plugin: missing bundle in "bootFeatures" feature

[Rodrigo Serra]

Hi,

I try to make a karaf assembly with all bundles in system directory to avoid 
internet connection o using mvm mirror. All looks good until the "transaction" 
feature. In the system folder of the generated assembly, there are a missing 
bundle required by this feature:  
mvn:org.apache.geronimo.specs/geronimo-jta_1.1_spec/1.1.1

Some body know what is happens?

This is the plugin configuration:

            <plugin>
                <groupId>org.apache.karaf.tooling</groupId>
                <artifactId>karaf-maven-plugin</artifactId>
                <version>${karaf.version}</version>
                <extensions>true</extensions>
                <configuration>
                    <resourcesDir>${basedir}/target/resources</resourcesDir>
                    <bootFeatures>
                        <feature>jndi</feature>
                        <feature>jdbc</feature>
                        <feature>transaction</feature>
                        <feature>derby-server</feature>
                        <feature>wrapper</feature>
                        <feature>sgc</feature>
                    </bootFeatures>
                </configuration>
            </plugin>
