Could not run features-maven-plugin's generate-features-xml goal.

[srinj63u]

Hi,

I am trying to generate features.xml using features-maven-plugin. The environment is jdk1.6.0_17, apache-maven-2.2.1. My code snippet is :

                        <plugin>
                                <groupId>org.apache.karaf.tooling</groupId>
                                <artifactId>features-maven-plugin</artifactId>
                                <version>2.2.4</version>
                                <executions>
                                   <execution>
                                      <id>generate</id>
                                      <phase>install</phase>
                                      <goals>
                                        <goal>generate-features-xml</goal>
                                      </goals>
                                      <configuration>
                                        <outputFile>target/features.xml</outputFile>
                                      </configuration>
                                   </execution>
                                 </executions>
                        </plugin>

When I try to run the plugin, I am getting the following exception:

org.apache.maven.lifecycle.LifecycleExecutionException: Internal error in the plugin manager executing goal 'org.apache.karaf.tooling:features-maven-plugin:2.2.4:generate-features-xml': Unable to find the mojo 'generate-features-xml' (or one of its required components) in the plugin 'org.apache.karaf.tooling:features-maven-plugin'
