maven-jar-plugin question

[robert . egan]

The following POM works as expected when run by itself (it uses 
org.apache.maven.plugins:maven-jar-plugin:2.1:jar) but when run as part of 
a multi-module build it uses 
org.apache.maven.plugins:maven-jar-plugin:2.2:jar. Does anyone have any 
suggestions as to why this happens and how I can resolve it?

The reason this is an issue is that it needs to construct an empty jar, 
which was disallowed in 2.2.

Thanks
Robert Egan

PS: I'm not allowed to put an empty file in the jar, as has previously 
been suggested. The reasons are political, not programmatic, and quite out 
of my control.
