[jira] Commented: (MNG-4979) Cannot override configuration parameter from command line

["Stefan Birkner (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MNG-4979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=251641#action_251641 ] 

Stefan Birkner commented on MNG-4979:
-------------------------------------

I looked at the code of org.apache.maven.plugin.DefaultPluginManager.getConfiguredMojo(...) and discovered the reason for this bug. The line

 PlexusConfiguration mergedConfiguration = mergeMojoConfiguration( pomConfiguration, mojoDescriptor );

sets the skipTests parameter to the value of the pom. Afterwards this value is not be overriden, because it is already set.

> See the attachements for a sample project of the surefire integration tests.
> Its pom sets the skipTests option of the surefire-plugin to false.
> <plugin>
>   ...
>   <configuration>
>     <skipTests>false</skipTests>
>   </configuration>
> </plugin>
> This configuration is not overriden by the appropriate command line parameter:
>  mvn -DskipTests=true test
> Executing this line will set the skipTests parameter of the Surefire plugin to false and the tests will not be skipped.
