Hei, [This question is highly related to plexus]
How does one pass an empty value in the configuration of a plugin ? I am facing the problem using the exec plugin where I need to conditionally enable a parameter based on a profile. It looks like maven doesn't differentiate between empty elements in an array. in <arguments><argument></argument></arguments> I've tried <argument></argument> <argument> </argument> <argument><![CDATA[ ]]></argument> (I also tried with tabs) <argument>" "</argument> <argument>' '</argument> The first 3 are treated identically and the argument is filled with null in the plugin config. The last two break the command to execute. I followed the maven code and it looks like a limitation in plexus-container, probably because of overzealous trimming. To me this is a limitation. Why is the parser removing content from my config ? Is this something we want to fix ? I doubt as it would not be backward compatible. Any workaround to achieve my goal ? I know I can create a different configuration in my profile but that duplicate a lots of code for not much gain. In the worst case, I can change the exec mojo to just ignore those empty values. But that will only solve the problem for my plugin.

Set the argument to an empty value" 144 + " if this is the required behaviour." ); Cheers, Jerome --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
