Subject [jira] [Created] (AXIS2-4985) NullPointerException in axis2-aar-maven-plugin if no fileSet is specified
Date Wed, 23 Mar 2011 17:34:05 GMT
NullPointerException in axis2-aar-maven-plugin if no fileSet is specified
-------------------------------------------------------------------------

                 Key: AXIS2-4985
                 URL: https://issues.apache.org/jira/browse/AXIS2-4985
             Project: Axis2
          Issue Type: Bug
          Components: Tools
    Affects Versions: 1.5.4
            Reporter: Reto Huber
            Priority: Minor


A NullPointerException is raising by generating the AAR files using the maven2 plugin axis2-aar-maven-plugin.
The exception will raise if no FileSet is configured.  If there is a FileSet specified in
the configuration the plugin works as expected.


Example of a maven2 plugin configuration that will raise the exception:

<build>
	<plugins>
      					
    		<plugin>
			<groupId>org.apache.axis2</groupId>
			<artifactId>axis2-aar-maven-plugin</artifactId>
			<version>1.5.4</version>
			<extensions>true</extensions>
			<configuration>
				<outputDirectory>${basedir}/dist</outputDirectory>
        	</configuration>
    	</plugin>
	
	</plugins>
</build>


Exception:

org.apache.maven.lifecycle.LifecycleExecutionException: Internal error in the plugin manager
